A Catalyst 2955c-12 just make me mad.The client complaint that his network management software kept alarm about 4 2955c-12 in his lan. From any device I ping to those concerned devices' management IP address, there are 500 to 600 ms delay, though no lost packets. Those 2955c-12 are all conected to a WS-X4124-FX-MT line card of a catalyst 4510R ,which is the core switch of the lan,through its 100base-FX optical fiber interface .Even I ping from 4510R, there is reply delay. I have no idea what's going wrong. Anyone help?
Thanks in advance.
Once I face a similar problem where I was not getting snmp response from the same model switch. The problem looks like of 'memory low'. When the switch was rebooted it again start responding to snmp. Rebooting may not be the right decision.
Check if you are showing memory low, sho memory.
