0.2.7-RC1 - PowerPC platforms
Hello all,
The 0.2.7-RC1 release is available. It mainly introduces support for the PowerPC architecture. You will be able to mix MIPS and PowerPC platforms in the same hypervisor instance.
New platforms, port adapters and features:
- Cisco 2600 platform. Possible Network Modules: NM-1E, NM-4E, NM-1FE-TX, NM-16ESW. NM-4T is not supported. This platform is very good for “CE” routers (less memory and less CPU power used) in your labs. Don’t forget to set the appropriate amount of RAM for recent IOS images ;
- Cisco 7200 NPE-G2: basically working (excepted integrated GigabitEthernet ports), but not recommended for common use (a lot of bugs remain) ;
- Cisco 7200 new Ethernet Port Adapters: PA-2FE-TX (2 FastEthernet ports), PA-GE (1 GigabitEthernet port), C7200-I/O-2FE/E, C7200-I/O-GE+E. These PA and IOcards are based on the Intel i82543 chip, which is incompletely emulated. Please let me know if you encounter strange problems with them.
- Greg Anuzelli added support for PCAP capture on virtual interfaces. You can capture Serial (Cisco HDLC, PPP, Frame Relay) and Ethernet packets. ATM is not supported. This will require a Dynagen upgrade.
- “Sparse memory”: this feature will allow to start more routers per hypervisor instance. The virtual memory is only allocated when required, and Ghost RAM is loaded only once (if used). This will also require a Dynagen upgrade.
Bug fixes:
- NM-16ESW: discard flag in Port Table was incorrectly handled (please see http://7200emu.hacki.at/viewtopic.php?t=686)
- PA-POS-OC3 now works with all NPE models.
About the switch platforms (3550, 3560, …), please read http://7200emu.hacki.at/viewtopic.php?t=658 , whose the conclusion is that without the help of Cisco Systems, it is probably impossible to do it (specific ASICs, POST tests at boot, etc.)

Hi Chris,
Thanks a lot for all your work.
I have access to a big Cisco LAB. Please let me know if you need some hardware infos (Pictures of some cards, … whatever).
February 15th, 2007 at 3:31 am
Chris:
Your emulator platform is, without any doubt, amazing and the best.
Thank you for your permanent effort and excellent work.

hi Marpione could u pls tell me how to use them . i mean what switches i need to use in dynamips. i don;t use dynagen.
February 15th, 2007 at 6:22 am
hi chris is it possible for ur to get the 4-t card also working for serial interfaces. it will be great . thanks a lot for this great innovation.

February 15th, 2007 at 7:57 am
hi chris can u pls specify the 2600 router models which are supported in this release. are the the normal 2600 series routers or the XM series routers.
i tried loading both of them it starts with loading and then says shutdown.
none of them seems to work.
can u pls help.
regards
sebastan
February 15th, 2007 at 8:03 am
sebastan> To display the models, just use “dynamips -P 2600 -h”. You set the model with “-t” option (like “-t 2610XM”). Uncompress the image before booting it, there are problems to boot compressed images directly.
Thanks to all for the nice words.
February 15th, 2007 at 8:09 am
Great job !
February 15th, 2007 at 9:29 am
hi chris thanks a lot . i hope u could add that switch thing in the release note. it will be really helpful to people.
chris could i just ask u is there is a difference between the 2610xm and 2611xm models. i guess both the XM models are based on the same hardware architecture.
cause i could see u could make 2610xm,2620xm and 2650xm and not the odd series. i was just wondering .
chris i have also asked helped from people in linux-mips.org. to find out abt any hardware level debuggers which could tell us abt how we can guess the hardware architecture with the post test and all.
have u checked out that site. they have added many links to ur site. as a example for mips emulator.
i think u could get help from people in that forum.
i know that the switch thing is impossible without cisco;s help but i am still trying for some help.
i guess even the pictures of the chipset won;t be of any use to u right.
if they could help u chris pls let me know. so i can send them to u .
waiting for ur reply chris.

February 15th, 2007 at 12:41 pm
Sebastan : stop moaning about things you clearly don’t understand. If there won’t be a catalyst emulator, get over it and get on with your life, and stop harassing Chris about it. BTW, your continued use of ‘u’ and ‘ur’ instead of ‘you’ and ‘your’ is not exactly a proof of intelligence/etiquette.
Chris, great work. I’m amazed.
February 15th, 2007 at 2:07 pm
Chris you ROCK! Some people don’t really know or appreciate what you have done and want more modules and more chassis. but these are the people that don’t know the difference between any of them anyway and would be better served by Boson. HA. Keep up the good work
February 15th, 2007 at 3:25 pm
Thanks Chris
February 15th, 2007 at 3:30 pm
Great work,
but not only built-in Gigabits don’t work.
“no shut” on the build-in interfaces of C7200-IO-2FE leads to IOS (12.0(32)S6) hang-up. Comman line just stops.
February 15th, 2007 at 3:40 pm
But this happens only when the socket is bound to built-in FEs.
If there is no socket bound - box survives no shut… Though such interfaces are useless…
February 15th, 2007 at 5:52 pm
hey pk i am not complaining abt anything . i am just asking abt things that would be required for emulating the catalyst. i got resources by which i can help what he is looking for. but i just wanted to know what will be required for that.
i am not cribing abt any module and chassis i am very much happy with dynamips and what chris has given us. i am using it everyday for 5 to 6 hrs.
u don;t tell me that i am asking for more and more like other.s

Hi, Chris,
My high regard to you…your work has helped a lot people…
Had no issue so far with x86/_64, lab running fine, but perhaps need a little direction for PPC related issue.
I encountered some error when compiling using powerbook G4.
It related to rom2c.c and utils.h
Some parse error, undeclared and incompatible implicit declaration.
Does it need certain version of gcc compiler or else ?
any advice or direction would appreciated..
Again, thanks to Chris….
February 15th, 2007 at 8:18 pm
Chris, many thanks for yout great works…..
Is any update available for Dynagen?
February 15th, 2007 at 9:01 pm
I would like to thank you fo your try and your offer. Great job for one more time.
You’re helping me a lot.

Chris,
about NM-4T and 26xx. It is unsupported by the real 26xx hardware so I think it will be impossible to emulate it on the not supported platform. The only hardware exclusion from 26xx is 2691 for which it is supported.

February 16th, 2007 at 11:11 am
Thanks for the new release. I have one question: If i want to use the 2600 with dynagen, it requiers a new release of dynagen? Becaue:
dynagen lab1.net
Reading configuration file…
fujitsu, router R2, model = the value “2600″ is unacceptable.
fujitsu, router R1, model = the value “2620″ is unacceptable.
Thanks
February 16th, 2007 at 11:49 am
I’ve the same problem like Mihai.
Any idea about the new version of Dynagen?
Thanks!
February 16th, 2007 at 12:13 pm
of course guys it won’t woooooooork! Didn’t you read Chirs release notes? and by default and by common sense, any NEW features WILL require and updated DanyGen because ultimately the current release cannot understand that Prof Chris has made it possible to run the 2600 and neither it can update itself by itself!
Greg Greg, there is a new release of Dynamips! where are you brother!!
I can’t wait to test the new ghost RAM feature! Can it make me run 20 Routers at one time on my dying PII PC with 64RAM?! ahhahahha that will be swwwweet! 
February 16th, 2007 at 8:15 pm
Hi Chris, thanks a lot for this tool! This makes my life way easier at Cisco TAC

Hi Chris,
Thank you for the new release. Your work is very invaluable for me. Keep the faith for the 3550 and 3560. Hopefully, Cisco Systems (or maybe other people) can give help for the POST test at boot, the specific ASIC etc.
I can run a 2600 IOS with just 16MB RAM. Impecable!
Little question, how to include NM-16ESW module in 2600 platform?
Which 2600 IOS can run NM-16ESW module? I have tested some old IOS whit no result.
Thank you

Wow,
Looks like PK’s been a naught boy!. Just ignore the comment since one bad apple does not always ruin the bunch.

Network.Freek ====> you cant include the NM-16ESW module in 2600 platform i guess, coz its only supported on 36xx routers, please anybody confirm am giving right infos.
still waitting on someone to tell me how they able to run the 2600 router since the new relase did not published yet !!

Hi,
I am very interrested to test the 2600 platform.
—
From Chris’ announcement:
Cisco 2600 platform. Possible Network Modules: NM-1E, NM-4E, NM-1FE-TX, NM-16ESW. NM-4T is not supported. This platform is very good for “CE� routers (less memory and less CPU power used) in your labs. Don’t forget to set the appropriate amount of RAM for recent IOS images ;
—
NM-16ESW is supported in Cisco 2600 platform. But as I have said, I’ve tried this module on some old 2600 IOSes with no success. Need try newer 2600 IOS to get the benefit of this switching module on 2600 platform.
It will be also awesome to have serial interface module working with 2600 IOS. Is there serial interface module supproted in 2600 platform?
Many thanks
February 18th, 2007 at 3:45 pm
Support for NM-16ESW apparently extends to all 2600 series routers based on: http://www.cisco.com/en/US/products/hw/routers/ps259/products_data_sheet09186a00801aca3e.html
This worked for me:
dynamips-wxp.exe -P 2600 -r 64 -X -p 1:NM-16ESW C2600-IS.BIN
I decompressed IOS 12.3.22 IP Plus, which seems to support the module just fine.
February 18th, 2007 at 5:01 pm
Thank you ccie14745. I’ve just tried some new IOSes and nm-16esw is recognised using just 48MB RAM. This is one example that tested and worked:
dynamips-w2000 -r 48 -P 2600 –idle-pc=0×804b0cc0 -X -p 1:NM-16ESW ..\C2600-ip.BIN
the IOS is c2600-ipbase-mz.123-19.bin
Now I want to simulate frame relay with 5 virtual 2600s. The problem is, I still don’t know how to simulate serial interface in each virtual 2600.

Or somebody has a better idea?

February 18th, 2007 at 8:10 pm
I just released Dynagen 0.9.0. Changes:
* Added packet capture, via the “capture” command. Capture files are written to the host on which the dynamips server is running in PCAP format (i.e. can be opened with tcpdump, Wireshark, etc.). I’ll add a more detailed walkthrough of this feature in the tutorial soon.
* Added support for all the new 2600 models Chris just added
* Added support for sparsemem. Enable with “sparsemem = true” at either the top level of the network file or in the device defaults or device section
* Support for the new adapters for 7200s: PA-2FE-TX, PA-GE, C7200-IO-2FE, C7200-IO-GE-E. Specify the new IO cards with “slot0″ options, and the new adapters with “slotx” options, where x is 1-6.
* Support for the new NPE-G2
It turns out Sourceforge is having an extended outage of their ssh access (for the past few days and possibly extending until the 21st!) which means that web pages cannot be updated. So I’ve temporary thrown up a new page for Dynagen at http://dynagen.googlepages.com until I have the time to put together something more permanent. So please look there for the new release.
Finally, at the gracious insistence of some really great folks here at the blog, forums, and via emails I’ve decided to accept donations via Credit Card / PayPal via the web site. I’ll use the funds for the betterment of the Dynagen project (for example, to replace my aging P4 development / dynamips server, acquire Cisco hardware, etc). Dynagen is (and will remain) free, so please do not feel obligated. But if the existence of the project has helped you out (e.g. saved you money in purchasing CCIE study equipment) and you feel like showing your gratitude donate whatever you feel is fair. And hopefully Chris will get a donate button set up on his site soon so folks can send some well deserved gratitude his way too.

Nice work Chris, and Greg. Both your utils/apps/programs are more than helpful. I use them both in daily working life to test router configurations.
I have asked this before and didn’t see any response. Is it possible to simulate/emulate the PIX platform (PIX 505, 515, 515E, 525, 535)? If these could be emulated it would be awesome.
Keep up the good work everyone who is developing for this wonderful simulator and associated apps.
February 18th, 2007 at 11:33 pm
Can you post a section of your lab that recreates the problem? I’ll take a look at it.
February 19th, 2007 at 2:43 am
Greg, i guess people did not get your option with the 2600! Maybe they put [2600] instead of [2650XM] for example! That “XM” is the whole story guys!
February 19th, 2007 at 3:12 am
BUT! I got strange results (my console becomes something like faulty TV screen :)) when i use the follwoing config:

Hi all,
I’ve been running dynamips for a while and got use to the cli implementation. Is it worth while converting my understanding to dynagen? Or can I still do most things with the cli? I’m just wondering if I’m missing something :).
As alway, love ya work Chris,

Chris makes it very plain that half of the XMs are working yet. I would only play with these features if you intend on helping Chris work out the bugs involved. Until serial connectivity is implemented, the 2600 routers aren’t useful in most topologies anyway.

I’d just like to point out to those studying for CCIE labs. Serial is important, but only a very small part of the real exam. Routing, switching, QoS, Multicast, etc which all run on the less resource hungry 26xx
Also the only main difference between the 26xx and the XM is processor performance, memory and DSP, which I don’t really think is that relevant for most scenario’s (correct me if I’m wrong). If you need serial use a couple of 7200’s for the frame cloud and 2600’s connected for everything else.
Just thought I’d mention.

Thanks a lot Greg for your help.
I tried to configure a C2600 (C2620 XM) with a NM-4E interface but only one interface (E0/0) was available all the rest
interfaces were not.
I was trying this using two different ios images (c2600-adventerprisek9-mz.123-14.T7.bin, c2600-jk9s-mz.123-22.bin) but the result was the same.
Any idea?
Thanks a lot

Jumbo,
If I could I would help but i cannot .. since i’m on the TAC, my account is limited to TAC resources, and has no access to engineering notes/documents..
So just like everybody else, I’m hoping that some day some other gays pops up with the requested information
anyway, Chris if there’s anything I can do to help you let me know
February 19th, 2007 at 11:42 am
sorry for the misspelling, i guess it’s still too early in the morning
February 19th, 2007 at 3:26 pm
digital,
LOL I see what you mean about the “TV screen”. Errors scroll by so fast it looks like static. There is a problem with some of the newer images (ones that can typically only be used on XM routers). Chris has fixed this and the next version should contain the fix.
February 19th, 2007 at 3:47 pm
Regarding the NM-16ESW, it seems to be touch and go depending on the IOS image set. For example, it works fine for me using 12.3.22 IP Plus on a 2621, but it is not recognized on a 2610 using IP/FW/IDS PLUS IPSEC 3DES BASIC. In this case you see the module in a show diag, but it is not recognized. I would guess this is an IOS issue, not a dynamips issue, because I see it in the show diag.
February 19th, 2007 at 3:58 pm
zerich0,
The NM-4E showed up in the config for me in a test I just did using a 2620XM. I was using 12.4(12) advanced ip services. By the way, don’t forget to increase the RAM allocated to the router if need be. By default dynamips only allocates 64 MB and some images will need more than that.
February 19th, 2007 at 5:11 pm
Hi Guys
i maybe wrong on this
but after the sparse mem option - has anyone noticed any increase in the CPU consumption
or maybe its just me
Chris- You Rock!!!! merci beaucoup
thanks

February 19th, 2007 at 9:34 pm
Chris
I believe you have done a great and a lot of work on the cisco router, we own you a lot on your personal efforts.
do you have any plan to develop something similar on a Juniper router ? like M5 ?
February 19th, 2007 at 11:15 pm
Yes i did notice “a little” increase but that’s O.K!
Sparse mem option reduced my “mem” consumption from “4GB PF” to only 1.2GB! This is an amazing improvement!
The ability to fix bugs and improve the overal performance AND adding new router models in just 2 months that’s more amazing than the “DynaLove” itself!
Chris, what do you eat man? Maybe i should eat the same food! heheheheh
February 20th, 2007 at 4:56 am
Chris Chris,
I tried “sparseCPU= true” and “bringback_PentiumII_toLife = true”
and said dynamips “stop asking too much too soon”
Thanks for the new release- the memory consumption has just reduced dramtically-
Amazing work, Chris
Truly wonderful
cheers!
February 20th, 2007 at 6:08 am
Does the sparsemem feature work with the real memory(mmap=false) ?
February 20th, 2007 at 8:38 am
can you help me;
i have installed 0.2.5 it works, but how i can upgrade, i have dropped the files in the directory but i still get msg.
Error: Unknown command ’set_con_tcp_port’
plz help
February 20th, 2007 at 12:55 pm
sada, i don’t see any reason to delete the old version before installing the newer one! even if you did, installing the new version should put every file back to its normal place!! For upgrading, just double-click on the .exe setup file and follow the instructions to install!
February 20th, 2007 at 2:20 pm
Greg,
I think that I found the error. When I put the NM-4E interface in slot 1 everything was ok and the 4 ethernet interfaces were available plus 1 FE in 0/0 (by default I think).
When I put it in slot 0, only one interface (E0/0) was available.
Thanks for your help!

dam1on - IMHO, having spent a lot of time trying to figure out how to get the command-line options to work with DynaMIPS, I think it is better to use DynaGen. There are some things which are just easier, like the application of the idle_pc value dynamically (maybe this is a hypervisor feature, which I haven’t fooled around with in command-line mode). Also, the using INI-type files helps to draw out your configuration in a relatively easy-to-picture-and-parse format. No having to worry about ports, etc., also makes life easier, and so I also grappled with whether I wanted to beat my head against a wall to work out the command-line issues (syntax, ordering, ini-file maintenance, etc). Also, since the learning curve for DynaGen is so slight, you lose nothing by the small investment in giving it a try.
February 20th, 2007 at 4:08 pm
Mark> I’m already using idle-pc, and other “features”, i.e.
-X
-G
-idle-pc
-b
-f
So is there any benefit moving to dynagen? i.e. am I missing something other than just simplification? There’s mention of “sparsemem” and CPU, and somebody mentions a mem saving from 4gb down to 1.5. I run around 4 routers on a macboo pro, with 1gb of ram just fine (apart from the heat

HI guys
i have tried getting the best idle-pc value for IOS 3700 Software (C3725-SPSERVICESK9-M), Version 12.4(4)T7
Each time none of the values returned via Dynagen had a “*” marked next to it indicating the potentially best value
each single instance of a 3725 with this IOS gives me 32% CPU
has anyone had better luck ??

February 20th, 2007 at 6:42 pm
dam1on - DynaGen doesn’t enhance DynaMIPS as far as I know, it’s just a front-end. I tend more towards a command-line mentality myself, but I like the ease of using DynaGen (including the aforementioned dynamic application of the idle_pc value without having to restart the instance, which was new to me at least) including the ability to then just share the ‘.net’ files with others rather than the cumbersome CLI syntax/batch-files/scripts and associated virtual FR switch, etc. files.
February 21st, 2007 at 10:52 am
Prof Chris,
I just noticed something! Why the 3640 routers (with the 16ESW module) generate a HUGE vritual RAM file compared to the 7200? In the previous version when i set the ram = 128 i used to get “c3600_R1_nvram” file that is 128KB size but now it’s 128MB! :S The 7200 is still 128KB which is normal and “compressable”
Thanks again!

Hi all,
I’m trying to do some QoS labs and setup 2 routers with a fa link between them. Also one router has a tap0 interface to the local linux machine. The linux machine has a 8mb file on it and it running tftp server. It seems to take a long time to tftp the file through 1 router to the other (long time = hour(s)).
Is this expected? What sort of throughput should I expect? Is there a way to improve? QoS is difficult if things aren’t to some kind of scale, no big deal if this is what is expected though, I can always use the real stuff.
Any comments welcome,
Thanks again,
D
February 21st, 2007 at 2:58 pm
dam1on - You know, short of telnetting through a NIC interface, I haven’t tried sending files (yet) through the virtual network, so I can’t say if that’s normal behavior or not. How well does it transfer when you aren’t messing with QoS? That would be my baseline (i.e., if transfer speeds were 50% of what I would expect with real equipment, then I would expect at least half the performance with QoS as well).
It doesn’t really sound as I would expect though, so I would check the following if the TFTP server had logged any comms problems (such as re-transmits, or if the router shows long periods of …!!….!…. during the transfer). Either way, I would probably monitor the traffic as it goes through (for example, on the linux box use tcpdump or snoop) to try to get an idea of how it looks. One other thing I used to notice was that I had to set the speed / duplex on the Fa interface I mapped to my NIC port explicitly (but you should see any duplex error messages in your console logs). I don’t think any debugs would help you based on what I know of your problem.
Anyway, that’s my 2 cents.
February 21st, 2007 at 3:11 pm
Hi Mark,
I’ve not put any QoS features on yet. I use the tftp server for other real things. I most get good results in terms of file (i.e. !!!!!!!!!!!!!!!!!!!!!!), however each one takes around 5 - 10 minutes. interfaces are all good, i.e. mtu, speed, duplex. I suspect it is something to do with interupts and clocks, etc as I’d expect maybe 20 - 40% of real performance (only a guess). Other things that might be affecting it are linux, if you think about it the linux host is processing the same packets 4 - 5 times (i.e. host -> router -> host via fa -> router, and back again).
Things like frame relay and lmi are slow too but not unusable. This maybe related.
Just so nobody gets the wrong end of the stick, I’m not complaining, just investigating ;).
Cheers

February 21st, 2007 at 7:55 pm
Dam1on: You’ve noticed what Chris describes in the Wiki:
“Of course, this emulator cannot replace a real router: you should be able to get a performance of about 1 kpps (depending on your host machine), to be compared to the 100 kpps delivered by a NPE-100 (the oldest NPE model). So, it is simply a complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA/CCNP/CCIE exams.”
Essentially, since there’s a software emulation occurring, don’t expect the get any real performance from the simulation. Real-world router/switch hardware is the only way to investigate QoS with proof-of-service testing. Dynamips just won’t support that.
Keep investigating though. Dynamips is an amazing development for network junkies the world over!
February 21st, 2007 at 10:00 pm
dam1on - I tested myself, WinXP NIC bound to a NAT-ed interface on a virtual 7200, virtually connected to another virtual 7200 via FastEthernet interface, and achieved a rate of about 1500 Bytes / sec … at that rate, I transferred about 3.25MB in ~30 minutes … not blisteringly fast, but considering how many other things I am doing on my laptop it’s about what I could hope for, I guess.
February 21st, 2007 at 10:02 pm
I should add that I am having other issues as well, and I have not overly optimized my configuration (beyond a decent idle_pc value for this image) - the source is another laptop on the same subnet as my laptop:
R02#copy tftp disk0:
Address or name of remote host [10.215.82.67]?

hi all can someone pls help me as to how to bridge 3 routers. i need 3 routers ethernet segment to look like a multi-access segment.
i am not using dynagen i am using dynamips. can someone pls tell me the command and the switches . i am not able to figure it out from the release notes.
i am using 2691 router in the emulator which loads with 2 ethernet interfaces in the slot 0.
waiting for ur someone;s reply.
regards
sebastan
February 22nd, 2007 at 6:59 pm
Sebastan - I also was getting frustrated trying to figure out the proper port pairs for multiple things, but DynaGen has spared me the problem. I would put reference a virtual ethernet switch where, for example his port 26010 would talk to router R1’s port 26011, his port 26020 would talk to router R2’s port 26021 and his port 26030 would talk to router R3’s port 26031. Provided, in the virtual switch config file you specify all his interfaces which you will be connecting to your virtual router interfaces to be all within the same VLAN, you should be good to go. IMHO, start using DynaGen - it really spares your brain-power for more important matters and you could lab that scenario up in minutes (in fact, it comes with a sample ethernet switch lab, I believe).
February 22nd, 2007 at 8:26 pm

Hi Chris,
just an info, is possible to run PPC platform faster on a mac/osx with G4 processor?
I mean, JIT goes faster cause with Intel cpu u can translate in realtime, maybe that just for a similar architecture like ppc and g4 things could go better?
(yes I’m a diehard risc fan..;) )
Thanks,

Sebastan> I had a bit of a struggle simulating a shared ethernet as well, so you might like to see the configs I came up with.
The trick is to create a config file and let one of the dynamips instances also act as a virtual switch or bridge.

hi,
I think i found a bug:
I have connect one of loop back network adapters to a switch and i am able to ping that loopback adapter. but when i disable it from windows and then re-enable it again then i am not able to ping that interface again without restarting the dynagen.
Can any one confirm this behavior? or i have some issue with my machine?
Thanks in advance.
Best Regards,

There, Rod spared me the trouble of labbing it up - that is what I was trying to say.
February 23rd, 2007 at 8:24 pm
hi rod thanks a lot man for ur detailed reply. could u pls tell me how to create the bridge.cfg file and where to place it.
and should the mapping mentioned in the cfg file be same as the mapping done for the routers in dynamips.
can u pls tell me the steps in detail.it would of great help to me .
thanks once again .
waiting for ur reply.

it kind a stupid question but how come i know which IOS relate to which 2600 type of router unlike 3600 series router IOS thay chases are already mantioned in IOS name like c3640 and c3660 but what i see is all of the 2600 series of ios are like c2600. soo i am lil bit confused or may be i am wrong. please correct me.
Kind Regards
February 24th, 2007 at 1:22 pm
hi beat u are right buddy. for 2600 series platform evenif u download a XM series ios or normal ios. the ios name starts from c2600 only.

February 24th, 2007 at 1:43 pm
Sebastan> The bridge.cfg or switch.cfg files can be created with notepad if you are using Windows or using vi if you are on linux.
In the example I posted, the IOS and the bridge.cfg or switch.cfg files were all located in the same directory I ran the router commands from. You should be able to specify the path to the files if you want to.
The mapping in the switch.cfg or bridge.cfg files should correspond to what you have configured in the routers.
P.S. I can’t take too much credit for working this all out, it is described in the release notes.

Hi Chris and all fellows,
I am wondering if any body tried Cisco Router and Switch Security Manager (SDM) to connect to a dynamips instance. SDM is included in new CCNP exams for configuring IPsec VPNs and other security features.
I did try it and I was able to connect to one instance (router) after enabling ip http server, creating a local user for privilege level 15 and bridging the router ethernet port with my PC’s LAN interface.
It loads all features but there is a problem. SDM cannot write config changes to the router. I see a message when SDM completes loading, saying “SDM needs to write a temporary file to your router’s Flash”. I think this is the source of problem, SDM cannot write changes to file based running config of dynamips.
Strange enough, some of the changes are written to running config, for example, I created a loopback interface and configured an IP address in SDM, the loopback interface was created in running config but ip address could not be written.
SDM is a wonderful tool for less experienced Cisco users to manage routers using a GUI interface. I think Chris can accomodate SDM connectivity in dynamips.
Thanks for this wonderful tool and looking for SDM support.
If anybody is looking for latest version of SDM, you can download one from this url:

CCIEbydynamips,
Sounds like you are saving your file in RTF format, not txt. Open the file with notepad and I bet it will look garbled there too.
February 28th, 2007 at 7:50 pm
big_gena,
I believe there is a bug with importing a config if an nvram file does not previously exist. Not sure if this is your issue or not. But if it is, do a “write mem” for each router, then restart the lab and say yes to import.

I wanted to check the coede to see if I can help with it
but i could not relly understand most of the code
Is it possible to produce more documentation and explanation on it so more people can contribute
I know I am not a very good programer but i think i can help if I grasp it a little more
Thanks
March 1st, 2007 at 2:08 pm
Greg A,
I did this, nothing work. Inside nvram file (*_rom) I can see my config, but router boots empty, and startup-config cannot be readed after router booted.
March 1st, 2007 at 4:29 pm
Greg A,
Wow!!! It depends on version IOS I use!!!
It doesn’t work with c3745-advsecurityk9-mz.123-13a.bin , but works with c3745-advsecurityk9-mz.123-11.T3.bin

Hi Chris,
i will request to have a look at
http://www.cisco.com/en/US/products/ps5854/products_qanda_item0900aecd802a9470.shtml
and if possible can you emulate any of these.
(EtherSwitch Service Modules (NME-16ES-1G, NME-16ES-1G-P, NME-X-23ES-1G, NME-X-23ES-1G-P, NME-XD-48ES-2S-P, and NME-XD-24ES-1S-P)
As these are more closer to 35xx functionality….
This is just hope… which is my best friedn.

Hello,
In the release notes it is written that PA-POS-OC3 is working, but I cannot make UDP connectivity between two instances using POS.
Can you please provide some information?
Thank You
March 4th, 2007 at 5:30 am
MyOwn,
about the EtherSwitch Service Modules and 3550 emulation
I want to share you my experience in this
I was able to do the CCIE LAb workbook using the current EtherSwitch module without any troubles!
So for CCIE emulation you are good
Iam only waiting for the Serial WAN emulation on the 2600 roiuters so I can work on the LAB with good cpu performance
Using the 3600 the routers gives slow ping response after applying routing redistribution and BGP and ospf session starts to timeout
March 4th, 2007 at 7:28 am
Aly,
I disagree with you that the current switch module is good enough for the IE! The disability to do more complex spanning tree topology (MST vs. PVST) calls the need for more advance switching modules! This is beside the the more advance multicasting and QoS which the 35xx has different command than the router!
As for emulating more routers, i do feel that it’s fairly redendant as we have more routers module to play with! I would suggest that more attention is given to security appliances than what we already have!
I wish i can know programming so i can help in this area! maybe after my current IE exam then i will devote more time and search.

Hi Digital,
I have attempted to use NM-16ESW with th dynamips with not much success. Well depend what the definition of success is. The NM-16ESW supports vlans and VTP in vlan trunking mode. Not in config mode.
Also bpduguard is has different options and there are no rootguard options. So not knowing what other differences there were between this module and a 3550, I gave up.
How did you overcome the differences. Was it my IOS I wonder.
Thanx

i have a nice suggestion with little investment.
take a good high end pc buy the intel quad multiple adapters. buy 2 3560 or 3550 and connect them to routers in dynamips. if i were going for ccie routing and switching or service provider then i would have surely done that. since chris has mentioned clearly that 3550 or 3560 cannot be emulated in any condition without cisco’s help.
regards
sebastan
March 5th, 2007 at 11:14 pm
Cake,
regardless of the IOS version/feature set, the NM-16ESWwill give you the same basic commands!
Mr. Sebastan is right! no option but to get the “real” switches with the quad card if possibe! (yah, i hate that “real” thing by now!)
As for me, i’m not that rich so i go with rack rentals to practice the switching portion!
Chris, are there any intension for the PIX in future? Some of the PIXes used to run on Intel processors previously
which i guess make it easier to emulate than the routers. No?
March 6th, 2007 at 5:39 am
hi digital online rack will be expensive. i would suggest buy second switches and sell them back once u are done will will get good returns for it.
if the NM-16SW

hi digital online rack will be expensive. i would suggest buy second switches and sell them back once u are done will will get good returns for it.
if the NM-16SW-G was emulated it still as lot many features a compared to NM-16SW.

March 6th, 2007 at 4:44 pm
lets face reality… if you purchase 2 3560 and 2 3550 each will cost you no less than 2k USD so total will be 8k or more. Where as you can purchase 2USD/hour a full rack. SO a purchase of 1k will be essentially equal to 500 hours which i personally are sufficient to go up to CCIE level, along with having Dynamips.
These are only mine personal views and nothing else.. Every one should have to know his limitations. But if some one can afford then he should have a rack.. … if I can i have two by now.

You only need to run the bridge from 1 router instance, not all 3.
Also you have “-b -i0 bridge.cfg” in your first instance.
It should be more like “-i0 -b bridge.cfg”

March 9th, 2007 at 1:54 pm
sebastan> Here’s what I would have to say on the subject:
1) Where you put the ‘bridge.cfg’ file doesn’t matter, so long as you specify the whole path after the ‘b’ switch. For example, if you put the ‘bridge.cfg’ file under your ‘C:\Progra~1\DynaMIPS’ directory (I used the 8.3 name for the “Program Files” directory because I don’t know if DynaMIPS supports paths with spaces), your command-line would include the following:
-b C:\Progra~1\DynaMIPS\bridge.cfg
2) The contents you had looked okay, although I had left comments (the lines preceded by ‘#’) in mine … below is a sample of a ‘Bridge_Ethernet.cfg’ file I had used for a lab for someone else … I’m pretty sure it worked when I used it, now I just let DynaGen automagically handle this for me:
IF:E990:udp:10990:127.0.0.1:10991
IF:E991:udp:11990:127.0.0.1:11991
IF:E992:udp:12990:127.0.0.1:12991
IF:E993:udp:13990:127.0.0.1:13991
IF:E994:udp:14990:127.0.0.1:14991
IF:E995:udp:15990:127.0.0.1:15991
IF:E996:udp:16990:127.0.0.1:16991
IF:E997:udp:17990:127.0.0.1:17991
ACCESS:E990:99
ACCESS:E991:99
ACCESS:E992:99
ACCESS:E993:99
ACCESS:E994:99
ACCESS:E995:99
ACCESS:E996:99
ACCESS:E997:99
It looks like, if you only copied his bridge.cfg, you did not specify what ‘vlan’ each port will be in (or what type ‘dot1q’ (trunk) or ‘access’).
3) Start using DynaGen as it takes that guess-work out of the equation for you. If you already have plenty to remember regarding pure networking, why waste precious brain-cycles on the caveats of command-line switches for DynaMIPS if you don’t have to? For example, the sample lab called ‘ethernet_switch’ has a ethsw1.net file with the following contents … which should look fairly uncomplicated (obviously it is a sample file, so to make it work with DynaGen on your machine, you’d have to ensure the path to the images is the same, and put in the correct NIC registry hash (for the last line) if you wanted to bind an interface to your real NIC):
# Simple Ethernet Switch lab

I think I see what’s wrong … I roughly re-created what you were doing, but using a 3640 with an NM-16ESW module (slot 1 only, so not how I changed the -s 0:0 to -s 1:0 for example) since that’s the only IOS I had handy … I see the problem you had with the bridge.cfg and I’ve realized I never used the virtual bridge, only the virtual switch - which is what I would recommend here as well (partially because I must’ve decided I couldn’t figure out the virtual bridge either, and also because you have the luxury of choosing different VLANs, trunk ports, etc). To make that work, change your bridge.cfg (or rename it to ethernet.cfg and change) as follows, and reference it with the -E switch instead of the -b switch:
IF:R1:udp:10000:127.0.0.1:10001
IF:R2:udp:10002:127.0.0.1:10003
IF:R3:udp:10004:127.0.0.1:10005
ACCESS:R1:1
ACCESS:R2:1
ACCESS:R3:1
The above section creates the mappings, and then places the instances into the same VLAN (1) as access ports.
The following are my actually lines for launching the three router instances:
R1.bat:
..\..\dynamips-wxp.exe -r 96 -X -P 3600 –idle-pc 0×603e0068 -p 1:NM-16ESW -s 1:0:udp:10001:127.0.0.1:10000 -i0 -E ethernet.cfg ..\..\images\c3640-jk9o3s-mz.124-10a.bin
R2.bat:
..\..\dynamips-wxp.exe -r 96 -X -P 3600 –idle-pc 0×603e0068 -p 1:NM-16ESW -s 1:0:udp:10003:127.0.0.1:10002 -i1 ..\..\images\c3640-jk9o3s-mz.124-10a.bin
R3.bat:
..\..\dynamips-wxp.exe -r 96 -X -P 3600 –idle-pc 0×603e0068 -p 1:NM-16ESW -s 1:0:udp:10005:127.0.0.1:10004 -i2 ..\..\images\c3640-jk9o3s-mz.124-10a.bin
Try that out and let me know if it works for you … Below is the proof that THIS configuration works:
R1#show run int fa1/0

I had the oportunity to go to a CCIE training. To my suprise I found a CISCO employee there. He mentioned that CISCO have an internal Emulator that they use to emulate routers only. But they do not emulate switches. He said it is because of the complex architechure of ASICS. I suppose CISCO could do it if they wanted to, but it must be expensive and time consuming for them not to emulate Switch for internal use.
March 13th, 2007 at 9:10 pm
hi cake,
that’s very interesting, because I’m a cisco employee as well but I never heard such a tool before
Are you sure he wasn’t referring to dynamips ? 
Whenever I had to use routers/switches to quickly check something I was told to use the lab equipment or to use the ‘calo’ system (which is a huge lab where almost all the cisco products are available for testing purposes), but nobody mentioned an emulator which could be also used
March 13th, 2007 at 9:34 pm
yLke> I’ve also heard of a cisco emulator already available (for Cisco use, anyway), and I believe it is Sun(SPARC)-based. IOUlive is what it was called, but I’ve never worked with it (no SPARC equipment available … that I want).
March 13th, 2007 at 10:32 pm
as i heard also, the cisco emulator is not as good as dynamips!!
If they only they can give the required
also, if they could not emulate the switches it is because the people
who tried were not Chris!
info to Chris!!! It will be solved!
March 13th, 2007 at 11:18 pm
yLke, I agree with cake on that. Cisco had or still have a Linux based router emulator that was first implemented with the idea that Customers will give it a try first b4 buying their products/hardwares.
March 14th, 2007 at 12:23 am
As I understand it IOU is only available to Cisco IOS developers and not the general Cisco tech staff. Also I heard its more generic, i.e. more platforms than dynamips.
March 14th, 2007 at 9:57 am
the iou is available for tac people for simulating scenarios. it;s a low cpu intensive program. and it does not boot a specific router series with like dynamips . it only boots the required ios to test features. it supports all the ios. for the switchs they have incorporated external switches that is connected via multiple nics on the ios machine.

Hi All ,
Can anoyone tell me How to connect two Gigabit interfaces together .
Can we use the following syntax in dynagen :
g0/1 = R2 g0/1
But after setting the ip and making it up .. it does not ping…
March 15th, 2007 at 3:02 am
Hi,
I am struggling with getting Dynamips running on 2 Laptops (via cross over cable) so that I can run the InternetworkExpert lab and don’t have a clue where to start to configure this setup. Your help experts are highly appreciated.

Vikas,
I found some bugs regarding gig interfaces in Dynagen yesterday. Currently gig interfaces are most likely unusable. But the fixes will be in the next release.
March 15th, 2007 at 5:47 pm
hi greg any idea what will be the new features available in dynamips.
just curious to know. what is chris working on these days.

March 16th, 2007 at 2:22 pm
Joseph> It’s pretty easy …. all you need is an ethernet interface on one of your virtual devices to be mapped to your actual NIC, for example, on each system - from there, it’s a simple matter of enabling Layer-3 on the virtual intefaces and pinging across. I’ve never actually configured two virtual networks to talk as such, but if I can get a virtual network to talk to a real one, then I know it’s possible.
For example:
C:\Program Files\DynaMIPS>dynamips.exe -e

would cause me to create the following to get my LAN NIC to talk to the rest of the world as follows:
dynamips-wxp.exe -X -i 996 -t npe-200 -r 128 -p 0:C7200-IO-FE -s “0:0:gen_eth:\Device\NPF_{18FEDCD8-0217-4C8C-A817-C6DF7F1DFB6E}” –idle-pc=0×613f0720 ..\images\c7200-jk9o3s-mz.122-15.T17.bin
and, for example if my TRUE operating system interface has an address of 10.215.82.42 and a gateway of 10.215.82.1, then putting an IP on the Fa0/0 interface as follows should let me talk to that LAN at least:
config t
!
interface FastEthernet 0/0
ip address 10.215.82.240 255.255.255.0 ! Make sure this address is available
no shutdown
!
ip route 0.0.0.0 0.0.0.0 10.215.82.1 250 name RL_LAN ! bound to physical NIC
!
end
!
ping 10.215.82.1
which, first ping will time out as ARPing, etc., occurs but subsequent ones should be fine:
Router#ping 10.215.8
*Mar 16 08:20:08.031: %SYS-5-CONFIG_I: Configured from console by console2.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.215.82.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 4/22/48 ms

and then just work out any issues with duplex settings, etc.

Mark, extremely thankful. Dynamips gave exceptions when running the command line. However, I managed to do it via .ini after digesting your post. Joseph.

Chris, i found a bug in STP again! My topology is as follows:
SW3
/ \
/ \
/ \
SW1/ SW2
\ /
\ /
\ /
SW4
There are 3 VLANs in every switch (VLAN 111, 222, 333) and every switch should be the root for one VLAN via the “spanning-tree vlan [VLAN-ID] root primary”, i.e SW1 is the root for VLAN 111 and SW2 is the root for VLAN 222 and so on.
The switches are connected via 2 fastE each that is bundled with EtherChannels and made into trunks.
Can you look into this issue pls?!
Thank you so much
March 17th, 2007 at 1:14 pm
ah it seems the blog forum screwed the topolgy! i will post in hacki forum!
March 21st, 2007 at 3:47 pm
This is a terrific tools. Thanks Chris.
A question:
I’m trying to create a switch environment with NM-16ESW on my laptop in the office. After using for 2 days, my switch port was disabled by company’s network guys (for excessive traffic I’m not quite sure the reason.) Any suggestion on that? what should I be careful or should I disable some specific services to avoid impacting the network environment?
Is CDP a culprit?
I was thinking if I don’t use eth option to bridge NIC, there should not be any traffic from dynamips to the network, the traffic should be contained on my local laptop. Am I right?
A lot thanks to Chris again.
March 22nd, 2007 at 3:45 am
YOU RULE!!!!
Please, keep up the excellent work. Your efforts are much appreciated by many.

Hi,
How to set Mac Address in dynagen? Thanks
March 27th, 2007 at 2:36 pm
Elac> As a network manager, they should not be able to tell you are running a virtual network if you have CDP disabled and are not participating in dynamic routing. More likely, there is something else (spyware / viral) running on your machine which is tripping their alarms. Since you have winpcap installed, you might want to run WinDump.exe a few minutes before you start up DynaMIPS, monitoring the connection to the network, and after you start DynaMIPS, monitoring the connection to the network, to see if you notice any difference in the traffic patterns … you will probably be able to filter out all kinds of crap. I am assuming you haven’t done anything strange like bridge two laptop NICs together, and bind one DynaMIPS instance to one of them, because essentially then you would be talking to the network.
March 27th, 2007 at 5:50 pm
Elac,
If they had bpduguard configured the virtual switch would errordisable the port. However that would occur pretty much instantly, not after two days. In any event, you shouldn’t bridge to a production network. In theory you could cause a lot of problems, e.g. injecting bad routes via eigrp/ospf/etc. And you are correct, not configuring bridging to your NIC will prevent any “packet leakage”.
March 27th, 2007 at 5:53 pm
Ah, I forgot the spanning-tree issue - good point. If you did connect a switchport with spanning-tree enabled to the network, not only might you have triggered their bpduguard (which they would wisely run), but if it weren’t for that, you could’ve caused spanning-tree to re-converge, which by default causes up to 45 seconds of interruption to that VLAN at least.

hello guys,
i got this error everytime i run dynamips, here’s the screenshot

April 1st, 2007 at 12:15 pm
noyp, is that really an error?
as for the “my net files just keeps on reading the config file”, just leave it until it finishes reading! It takes a while for first time users! not kidding!

thanks
Mihai
April 3rd, 2007 at 12:50 pm
_ali_> As of ‘June 2nd, 2006 at 8:45 am ‘, Chris suggested he may be able to make it available at some point. There was also a lot of discussion in July of 2006 on the subject, but since then Chris has made headway into emulating more important features, like different hardware platforms and the ether-switch module, in addition to memory usage improvements, etc. I would be willing to bet it’s still on the todo list, but probably lower than you might like. For me, as ISDN is no longer on the CCIE R&S exam, it’s not on my wish-list, although it would be helpful to fool with in general - not to mention would be nice to do away with expensive and still-crappy ISDN simulators in the home lab.
April 3rd, 2007 at 3:46 pm
Hello,
I’m not in a hurry. There are a lot of things I’ve learned using Dynamips and I am still learning a great deal.
I was curios I guess, that’s all.
10x for the effort, guys!
