C2960S Lanbase Routing Crashes

Hi,

I have 3 c2960s stack with sdm lanbase routing enabled. I was trying to move routing from a router to this switch stack. I have configured a couple of SVI and 5 static routers, which I believe is far below the docmented limit. It had been working fine for one week before I started to use it as a router.

The switch crashed when traffic was directed to it, ie. when it started routing traffic. In 2 hours time, it had 5 crashes. The error mesage says something about  "address error".

When I stopped using it as a router, it is working fine.

As these switches do not have SMARTNET services, I cannot get support from TAC. I hope someone here can give me some help.

2 crashinfo files are attached for your reference.

IOS version: c2960s-universalk9-mz.122-55.SE

Thanks in advance.

Re: C2960S Lanbase Routing Crashes

They have raised a bug (CSCtj37604) and its with the development team to fix.

Will probably have to wait for a new software release.

Hi,

I did some research and it looks like you are not the only one with this issue. I will give you more details later when I have more information.

Hi,

Does the release 122-55.SE2 resolve the issue?

Thanks.

Silver

Re: C2960S Lanbase Routing Crashes

Unfortunately not. However, will be fixed in 12.2(58)SE which is expected to be available around mid-March.

Andras,

I don't think Cisco dev is on track for this release.  It's now the end of March, and the latest is still 12.2(55)SE2 on CCO.

I have a customer affected by this, so need some insight ASAP on how Cisco are tracking with this fix.

Standing by eagerly......

There's a bunch of new firmwares/IOS scheduled for release before the end of April 2011.  I don't know if 58 is one of them.

Re: C2960S Lanbase Routing Crashes

I also have a similar issue with 4 x 2960-S in a stack configuration.

it was working fine for a few days in the lab, then started to crash when it was deployed and actually routing some traffic.

i have raised a TAC case for it and they have raised a bug for it.

i will provide more information once its available.

Thanks,

Re: C2960S Lanbase Routing Crashes

Hi There

I've just installed a Stack with four 2960S switches which we setup 3 vlans, once the routing mode was turned on we had a crash every 5 to 10 mins.

Turning off routing stopped the crashes. Our solution was sold to the customer on the fact that we would be taking some of his network traffic away from his existing router. Has anyone found a solution yet ? I will be contacting TAC after the weekend

Yup.  February is normally the start of IOS releases.

Re: C2960S Lanbase Routing Crashes

Yeah, that's the curse of low end switches. If something is cheap then you have to live with all these kind of issues. Not like higher end products wouldn't have nice bugs.

I'm hesitating to offer this model for our client, but if it is not resolved asap I need to find another product/vendor.

Actually it is a shame how a software release can be released with such a major bug.

It is the end of March now.

Re: C2960S Lanbase Routing Crashes

There's a new lot of IOS/Firmware releases tentatively scheduled for end of April 2011.  I am suspecting the 12.2(58) is one of them.

Silver

Re: C2960S Lanbase Routing Crashes

Hi,

The defect CSCtj37604 is already fixed in 12.2(58)SE which is expected to be released at the beginning of April. Please note that the release dates are just estimated and not guaranteed because it depends on several things.

Re: C2960S Lanbase Routing Crashes

I've been using this since Wednesday last week.  But as to whether I'm using the routing feature, I am not.

Community Member

Re: C2960S Lanbase Routing Crashes

Does anyone have any more information about this bug?

I'll get two 2960s and needed simple routing.

I saw the release of IOS 12.2 (58) SE1 but only says this:

CSCtj37604 (Catalyst 2960-S switch)

The switch stack reloads When you enter the ip routing global configuration command.

The workaround is to use the no ip routing global configuration command to disable IP routing.


This is not a solution!

Re: C2960S Lanbase Routing Crashes

Hi Diogo,

CSCtj37604 is fixed in 12.2(58)SE1 and 12.2(55)SE3.

C2960S Lanbase Routing Crashes

Agree it's not a workaround, on the other hand these are really designed as layer 2 switches, why not keeping routing on a device that is designed for that and known to do it well.

Community Member

Re: C2960S Lanbase Routing Crashes

I know that they are primarily layer 2 switches, but I need simple routing, and the difference to a layer 3 is great.

Andras Toth have you already tested this feature with the new versions of IOS?

Thanks for the reply

Silver

Re: C2960S Lanbase Routing Crashes

Hi Diogo,

Yes, I have tested it myself to make sure and I can confirm that in 12.2(58)SE1 and 12.2(55)SE3 it has been fixed and no crashing is observed when enabling ip routing. Also, the bug has been fixed and the developers have tested the fix before the new image has been released.

Best regards,

Re: C2960S Lanbase Routing Crashes

Good news my friend

thanks one more time for your reply

Re: C2960S Lanbase Routing Crashes

Hi Diogo,

Thanks for your feedback, I hope everything will work fine with your switches.

Please rate the posts which you have found helpful.

Re: C2960S Lanbase Routing Crashes

Hi Andras Toth,

I have the 2960s, but despite my template is "lanbase-routing", I still have 0 routed interfaces, and therefore I can't do inter-vlan routing

best regards

Silver

Re: C2960S Lanbase Routing Crashes

Hi Diogo,

Did you reload the switch after changing the SDM template?

When you say you can't do inter-vlan routing, what issues are you observing? Do you receive an error message when trying to convert a switchport to routed port?

Could you please share the output of sh version and sh sdm prefer from the switch?

Best regards,

Andras

Re: C2960S Lanbase Routing Crashes

Hi,

Everything is ok with the C2960S, include the inter-vlan routing.

Zero crash’s  since august

Thanks

Paolo your solution is good, but this site is very very small.
