Last Friday all my network went blank and I had to switch off/on both the Catalyst 4506 to get access. Then I receive e-mail from NMS stating that all my propvirtual was unresponsive at that time. Can anybody tell me what happen?
I'm not sure which log you referring to but I have a Device Fault Manager logs on both catalyst.
.253 is the PROPVIRTUAL IP
Hope this is the right one.
I was referring to the "show log" command on the switches to check if any information is recorded in the log buffer of switches which indicates of any problem.
you can also check on the switches as which interface is assigned with .253 IP.
i can see lot of traceback errors in the log which can be due to an IOS bug. Not sure if it occured at the time you have faced the problem or not as date and time stampings were not there for log event.
can u put output of "show stacks" and "show version" from your devices.
Sorry for the late entry. I have to take care of some business elsewhere. This is the stack and version information.
