0.2.8-RC1 release - Introduction of Cisco 1700 platform and WICs
Hello all,
The 0.2.8-RC1 release is available. It requires a Dynagen upgrade since the hypervisor control protocol has been modified. The new Dynagen release will be published by Greg soon.
New features:
- Support of the Cisco 1700 platforms, with WIC-1T, WIC-2T and WIC-1ENET cards (as for the 2600, the images need to be uncompressed before use).
- Support of WIC-1T and WIC-2T for the 2600 (2 WIC slots), 2691, 3725 and 3745 (3 WIC slots) platforms.
- Support of NM-NAM and NM-CIDS interfaces BUT this not means that you can use them out of the box. It means that you can connect your virtual routers to a VMWare, QEMU, … virtual PC running the NM-CIDS/NM-NAM code. I don’t provide a method to do this, but you can take inspiration here: http://7200emu.hacki.at/viewtopic.php?t=3095. If someone wants to document how to setup this, he/she is welcome.
- Plugin system (not documented yet) that allows to dynamically load new platforms. It is mainly for coding tests (it avoids to modify the dynamips core with temporary code).
Optimizations / Bug-fixes:
- New generic card framework to reduce the code specific to each platform (it is transparent to users, and was required for WIC support) ;
- Fixed JIT compiler for PowerPC and MIPS platforms on MacOS X (stack alignment) ;
- Fixed JIT compiler for PowerPC on 64-bit Linux platform (incorrect “bctr” instruction) ;
- Added ISL support for NM-1FE-TX card ;
- Fixed the Serial cards (NM-4T, PA-4T, PA-8T, PA-POS-OC3, WICs) to handle correctly CRC stuff. Now, you can interconnect them to the virtual Frame-relay switches.
Important note: The use of WIC cards is a bit complicated without Dynagen, so I strongly recommend to use it to mask the gory details.

Continuing my quest to avoid a 1.0 release at all costs, version 0.10.0 has been posted. The most important things in this release are support for 1700 platform emulation and WIC modules Chris explained above. The tutorial has gotten a general update, along with documentation for using the new WIC modules. It also now includes a section with an up-to-date hardware reference that details all the models emulated by Dynamips, which adapters are supported and in which slots. Questions regarding these issues are (understandably) common on the forums.
Version 0.10.0 changlog:
* Support for the 1700 platform new to Dynamips 0.8.0-RC1. See the tutorial for supported platforms and modules.
* Support for WIC-1T, WIC-2T, and WIC-1ENET. See the tutorial for supported router platforms and usage.
* Support for NM-CIDS and NM-NAM. Note these are just “stubs” (at least as of this version of Dynamips). You can connect to them using “IDS-Sensorx/0 = …” or “Analysis-Modulex/0 = …” but they don’t actually do anything. See the tutorial for platform support.
* FS#154 - added “confreg” command to set the configuration register of router(s) from Dynagen. e.g. “confreg r1 0×2142″ followed by “reload r1″. Note changes to the config register will not be displayed in a “show ver” until the router is reloaded.
* FS#182 - Second port of PA-C7200-IO-2FE was not usable
* FS#177 - crash on malformed interface entry in net file
* Dynagen now automatically picks a PA-2FE-TX rather than a PA-FE-TX when referencing a FastEthernet on ports 1-6 on a 7200. You can override this to mimic the old behavior with “slotx = PA-FE-TX”.
* the vbs file that launches SecureCRT sessions was missing from the Windows installer package
* Changed the state shown with the “list” command for virtual switches from “n/a” to “always on” to avoid confusion.
* Added an up-to-date list of hardware emulated by Dynamips to the tutorial. Thanks to ggee for performing the initial documentation in this post: http://7200emu.hacki.at/viewtopic.php?t=1831

Thanks again for striking… although i am little bit late.
September 8th, 2007 at 3:17 pm
My goodness, just when I really start missing an update on development, BAM!
Thanks again to Chris et al who make this project so fantastic.
Cheers!
September 8th, 2007 at 3:29 pm
Another groundbreaking stuff !!! congrats Chris and greg !!!!!
Addition of 1700 series really akes life a lot easier in testing commonly used scenarios .!!!!!! keep it up guys !!!!
September 8th, 2007 at 11:55 pm
Thank you, for your great work!

What is the motivation for creating 1700 emulation?
September 9th, 2007 at 7:00 am
Thanks a million Chris & Greg!!!
May i ask if the “new” 32bit Cygwin that can run on a 64bit systems is used in this release?
Thanks again

the 1751 and 1760 routers are not accepted with dynagen configs - ‘1751′ or ‘1760′ is not acceptable, what’s going on with this?
September 9th, 2007 at 10:38 am
Jonathan, I’m now running the 1751 routers, I experience no such thing with dynagen you describe. Are you really using the new dynagen version? Can you post your config?
September 9th, 2007 at 12:24 pm
I just posted Dynagen 0.10.1 for all platforms that fixes the NM-16ESW issue. Sorry about that one guys!
September 9th, 2007 at 10:07 pm
Hi Chris,
Congratulations with this new release and many, many thanks for such a great job. I can’t stop admiring your, man. It’s fantastic.
Well, although this release introduces WICs support for the 2600 and the new 1700 which is just great, some odd things have already started to happen, at least here. I beg you, do not consider this in any way as a complaint or something like that, but I coudn’t resist to post some of my observations. I’m probably the first who noticed some strange behavior with the new release. Let me explain.
First of all, I think there’s a memory leak somewhere. I successfully started two 1700 instances loaded with WIC-2T and connnected back-to-back. I was intending to setup a basic PPP link with authentication and accidentally misstyped the username on one side. Of course the link didn’t come up, but I noticed that the ammount of PF usage was constantly growing. After a while, dynamips crashed with some cryptic cygwin errors regarding a stack overflow. After a reload I realized my mistake and corrected it. This time the amount of PF usage was groing too, but not so fast. At least it was usable. I decided to put some basic OSPF on them. I’ve setup a loopback interface on each router, configured the ospf process and have annonced all networks present on routers, all of them in area 0. The OSPF neighbors went up as expcected but no networks were present in routing tables. Then a crash followed again. I recompiled dynamips from scratch using the latest cygwin dll. This didn’t help, too
I’ve tried another IOS, but no luck either. I coudn’t start OSPF over serial link in no way. I tested EIGRP and it works as usual. I don’t remember how many crashes I experienced exactly… but there were some.
So, I was jut wandering is it bad luck of mine or there are people that experienced the same? Because at this point, despite we can load WICs, they are not of much use.
Chris, if you need any additional information of any kind to figure out this bug, I will be more than happy to help you.
Thank you very much one more time.
September 9th, 2007 at 10:34 pm
Well, it’s basic:
[localhost]
[[ROUTER R1]]
model = 1760
ram = 128
image = c:\dynamips\1700\c1700-adventerprisek9-mz.124-16.bin
Changing ‘1760′ above to ‘1750′, ‘1721′, ‘1720′ or ‘1710′ just boots the router, however ‘1751′ or ‘1760′ drop:
Reading configuration file…
localhost, ROUTER R1, model = the value “1760″ is unacceptable.
Press ENTER to continue
I just checked with CLI dynamips - it works. So…there’s something wrong with dynagen. configpsec contains all the options, so I’m lost here…
September 10th, 2007 at 7:50 am
Thank you, Chris!
September 10th, 2007 at 8:57 am
Ultimate !!! Amazing !!!!
Thanks a lot Chris !!
September 10th, 2007 at 9:44 am
Hi, Chris and Greg,
Is there a mailing list for dynamips development?
Thanks
September 10th, 2007 at 10:21 am
Hey Chris,
I’ve just got this message when trying to execute Network Device List.
rommon_load_file: unable to create file c7200_i0_rommon_vars (No such file or directory)
It also appears every time I run .NET file.
Is this a problem or just a normal behavior?
Thanks in advance

You should change to /24 or /30 instead of /32! That is, they MUST be in the same subnet!

I used the 7200 Series BTW, i don’t have the 2600XM IOS with me now but i believe it should work too!
September 11th, 2007 at 12:24 pm
To Digital:
It doesn’t. See my post above. When using WICs the ospf doesnt work, although adjacencies a froming. And on Windows there’s a memory leak. After a while, probably depending on the ammount of installed RAM the dynamips craches. On Linux it works OK, I mean the dynamips not OSPF. On linux OSPF doesn’t work either when using 1700/2600 loaded with WICs.

Hi Chris and Greg,
first of all, thank you very much for another great release. However, there seems to be some kind of bug in virtual flash access. Every time I try to store something on flash:, I get Checksum error (tested on 2640 and 2620) - not a big deal for a router, but I use two 3640 instances with NM-16ESW as a switch replacement and I’m not able to store any VLAN and VTP information. As you all know, they are stored in flash in vlan.dat file. So I lose all VLAN information every time I reload my lab.
Can you check it out please?
Thank you
Rado
September 13th, 2007 at 7:35 pm
Hi Rado,
I have the same issue. There seems to be a problem with flash filesystem. I too cannot same my vlan information across reboots and erase flash: is not persistent across reboots.

Hello Chris,
Could you please provide a short guide on how to run the WIC modules using dynamips directly!
What is the syntax used to run them ?
Thanks
September 15th, 2007 at 6:19 pm
Congrats Chris for the new development of 1700 and 2600 support of WIC cards. Although didn’t test yet busy in my exams I am excited to use this new models and add them to my growing virtual network.
All the models you have been develop are currently using in my virtual LAB with Frame Relay, MPLS, vpn, connected to pemu.
Great job and thank you very much wait for my donation… hoping for development of 6500
September 17th, 2007 at 9:52 pm

Hello Crys,
First of all congratulations for the brilliant job. Regardin the last posts about OSPF problems, i tested basic OSPF area 0 configurations with several 2600 models (2610, 2650XM), versions 0.2.8 e 0.2.7 and with both 12.4.8 IP Base and Advanced Enterprises Services. In all cases the routers do formed adjacencies, but no router information was exchanged, even loopback addresses.
The same configurations was tested with 3725 models and worked fine.
Where are de Donations button on your page ?
September 20th, 2007 at 10:20 am
Hi,
has anyone seen any packet loss on the bulit-in FE interfaces on the C7200?
It seems I have them on MacOSX and I wanted to verify if someone else is seeing them.
Could this be a configuration problem?
TIA
September 21st, 2007 at 4:33 pm
Hello,
I faced with this issue: incoming CDP packets through WIC-1 and WIC-2T comes corrupted. So no CDP neighbors behind these ports in CDP table.
IP connectivity is Ok.
The laba is trivial - two 3725 with WICs back to back
In config just NO SHUT on interfaces…
Does anybody observeы the same?
September 21st, 2007 at 4:51 pm
Regarding OSPF seeing neighbours but not exchanging data:
Is the mtu size the same on both sides?

Chris/Greg,
What are the chances of getting PA-A3 support in dynimips in order to support PPPoE over ATM? I have seen similar requests in the past, but I am not certain that there has been a definitive answer.
Some research suggests that the LSI ATMizer II - L64363 is the main processor in question.
router# show controller atm 3/0
Interface ATM3/0 is up
Hardware is ENHANCED ATM PA - DS3 (45Mbps)
Lane client mac address is 0030.7b1e.9054
Framer is PMC PM7345 S/UNI-PDH, SAR is LSI ATMIZER II

Thank you very much. Is there any possibility to emu the cisco VPN3005? or, is there anybody that you know working on it?
October 6th, 2007 at 2:09 pm
hi,
I have installed 64bit gentoo linux to vmware in my laptop and running dynamips successfully. I loved it.
The problem is:
I am using SecureCRT to access the sessions, but after about 5 minutes character typing changed from real time to one key press late. Restarting dynamips server makes it real time again, but it lasts 5 minutes. Telnetting from the command prompt gives the same.
Anyone experienced such a problem?
Thanks in advance
October 6th, 2007 at 4:57 pm
Valentin Says :
That’s true and verified I have checked the same and found that router has not excahange in ospf. This problem only face when you use 2600 IOS
October 8th, 2007 at 10:00 pm
Hi, chris and all
Chris, thank you for the amazing idea and output.
All, I like to share my daily tools for doing the simulation through dynamips (hypervisor).
It’s an alternate portable GUI frontend based on tcl/tk.
It could be use for import & viewing dynagen topology too.
I am uploaded it on rapidshare.

*Mar 1 00:00:36.963: %OSPF-4-BADLSATYPE: Invalid lsa: Bad LSA chksum Type 5, LSID 10.0.0.0 from 150.1.2.2, 183.1.123.2, Serial0/0.123
Only redistributed routes causes that. Both inter and intra OSPF routes work fine. I think there is a bug in WIC emulation because that doesn’t happen with 3600 plataform.
I run dynamips version 0.2.8-RC1-x86 compiled from source on a Debian 4 box.

Hi everyone, I just downloaded the new dynamips ver 10.
I now testing the 1700 series, loading of image is fine but after that it gives me this error “Connected to Dynamips VM “r1″ (ID 0, type c1700) - Console port

here is my code:
# Simple lab
autostart = true
[localhost]
[[1720]]
image = C:\Program Files\Dynamips\images\c1700-advipservicesk9-mz.124.bin
[[ROUTER r1]]
model = 1720
WIC0/0= WIC-2T
WIC0/1= WIC-1ENET

You have to unzip the image like below (change name):
chris@portchris2:~/dynamips-0.2.5$ unzip -p c7200-advipservicesk9-mz.124-9.T.bin > image.bin
warning [c7200-advipservicesk9-mz.124-9.T.bin]: 27904 extra bytes at beginning or within zipfile
(attempting to process anyway)
Remember to do it with c2600 images.

Hello
is is possible to build dynamips on HPUX?
Thanks

Hi all,
I have a problem with my Dynamip, I can’t simulate any modles other than 7200. with 7200 it’s working great. but any other model the router doesn’t load and even the Dynagen doesn’t show any errors.
I tried to simulate 1720 and 1750 and 2600 models and telneted to it at it’s booting, this is what I got from my telnet program:
ROMMON emulation microcode.
Launching IOS image at 0×80008000…
Self decompressing the image : ############################################################################## [OK]
،c
does any body have a solution for this problem????
Best regards,
Mohammed Moustafa.

Hello,
I am a new_comer ,plesae advice me some question.
I used 2620 bin file, the installation seems to be fine but
from Dynagen management console I could telnet R1
but I got following message only [Connected to Dynamips
VM `R1 (ID 0, type c2600)- Console port.
I do not see any Router > prompt
2620 ISO ver is 12.1

Hello,
It seems to be fine after switching a bin file from c2600 to c3600.
Thanks,

I’ve had some issues trying to find good idlepc values for my linux debian computer laptop. i have 4gb ram and a core 2 duo 2 ghz processor. I am not sure if it is the image i am running, basically I picked /c3640-js-mz.124-25b.bin. The idlepc values I’ve chosen help a little bit but not enough to make me feel comfortable. Nevertheless, I have found that under linux there is a piece of sofware called cpulimit that allows me to control how much cpu I let dynamips borrow. Just in case someone else is interested, here is what I have done.
apt-get install cpulimit
dynamips -H 7201
dynamips -H 7200
ps -A u | grep dynamips
deuche 18542 15.5 21.8 1724472 453212 pts/2 SNl 11:49 5:08 dynamips -H 7200 20
deuche 18561 3.5 19.9 1250404 414868 pts/2 RNl 11:49 1:10 dynamips -H 7201 20
cpulimit -p 18542 -l 30
cpulimit -p 18561 -l 20
It is a little bit slower when you start the routers but I certainly feel more comfortable about the high cpu utilization.
