interesting CAR related crashes in 12.0(14)S
Hello, Does anyone know of any "interesting" bugs that are triggered on GSRs with CAR active running 12.0(14)S, preferably S3? The simptoms are
40% packet loss with the aggregate gige traffic being under 100Mbit/sec. The total number of VLANs that GSR sees is about 100...

Alex, Typically when people say crash they mean the router rebooted. But in your description you are talking about packet loss. Send me a 'sh tech' *OFFLINE* and a more detailed description of the problem. We'll post a response to the alias once it's a bit more clear what the issue is.

Alex,

I am talking about packet loss, crash, packet loss, crash, packet loss, crash and so on.
Send me a 'sh tech' *OFFLINE* and a more detailed description of the problem. We'll post a response to the alias once it's a bit more clear what the issue is.
I understand the point of image/damage control, thought at this time what I am interested is not a reply from Cisco along the lines of "please send the 'sh tech'". Rather I am interested in hearing from people who are using GSRs in non-lab environments about similiar issues since I happen to have a hunch that should I not get that background information myself, I would have a problem convincing people that the issue had even been there... So, returning to my original question... Does anyone know of "interesting" crashes related to CAR on GSRs running IOS release close to what I have described... (Since during the past tests the same router in the same setup with the same IOS ran just fine when it was applying same type of rate-limiting to 3x as much traffic on a different sub-interface) Thanks, Alex
Thanks, rodney

Alex, You may want to post to cisco-nsp@puck.nether.net instead as that reaches a slightly different audience (a lot of the same people) but has a lot more people that concentrate on the GSR. (Whereas some people here may not use GSRs). I would also recommend some more recent software than 12.0(14)S as that has a few security issues amongst other things that one wants to watch out for. - Jared On Mon, Dec 03, 2001 at 07:32:39PM -0500, alex@yuriev.com wrote:

I understand the concern though in this specific case, the entire reason we are running a specific image is that those issued had been addressed. Thanks, Alex
