Something strange with ICMP...

Hello,

I have a strange thing happening with one of my switches. It is a 4507, populated with four 48 10/100/1000 port blades. All of a sudden today approximately 25% of devices attached to these ports have stopped responding to PINGs.

The ports are scattered among all 4 blades. There are no other noticeable problems either... the PCs attached to the ports are working fine and their IP addresses even show up in the switch's arp table.

I have tried shutting then unshutting the ports and have cleared the arp cache on the switch.

Not sure what to try next... Anyone seen this before?

Thanks for any tips.

Charles
