Catalyst 4006 Router Module rommon prompt
Posted on 2005-04-16
Folks on our network use a VLAN on our Catalyst 4006 as their gateway. I restarted the switch after users began having issues with internet connectivity. It would come back up for an hour or so and then users could no longer get out through that VLAN again. I'm able to get users out to the internet by pointing them directly to our edge router, but our remote sites can no longer see our internal network.
When I plug into the switch console I don't see any issues with the modules. However, when I plug into the console of the router module I get the following error:
*** System received an abort due to Break Key ***
signal= 0x3, code= 0x0, context= 0x60929ca8
PC = 0x600b60ec, Cause = 0x20, Status Reg = 0x34018302
As soon as I plug in and get this prompt even the folks that were pointing to the edge router lose their internet connection- as they must go through this switch at some point. None of the usual commands like sh, dir, or format work at the rommon1 prompt. Not being a cisco guy I gave cisco a call for help. Of the three techs I chatted with each suggested a different problem, whether it be corrupt software, OLD software, or a bad memory module.
Before I start ripping out memory modules or uploading a new IOS, I wanted to see if anyone has seen this particular problem before. Can I do any additional non intrusive testing that doesn't involve my having to rebuild the router?
