I have multiple 4506 switches having a problem with snmp.
After upgrading to IOS cat4000-i5k91s-mz.122-25.EWA13.bin, these switches are having an issue being monitored via snmp.
It almost seems like the snmp agent is frozen. None of my monitoring software..i.e. CiscoWorks, HP OV, or any other MIB browser can access these devices via snmp.
I have IP connectivity between the Net Mgt. Server and these switches(I can ping all of them) and there are no ACLs.
I have tried renaming the community strings to ensure that they are correct and even tried stopping/starting the SNMP agent (via the no snmp-server command..and turing it back on), but still no success.
Also, out of the bunch that arent working, there are 3 4506 switches that "ARE" working with that same EWA13 IOS. I have compared the configs on the ones that are working and the ones that arent and they are all the same.
At this point, I am inclined to think that maybe there is a bug in this IOS, but not sure.
Thanks in Advance.
