Hoping someone may be able to help me track down this slight issue. Starting two weeks ago, one of our 4507R went from an average of 45-50% usage to being pegged at 95-98%.
We really hadn't noticed it until we started looking at the graphs. Performance still seems to be ok. There are no packet loss while connected to the system, users aren't complaining, etc...
While troubleshooting this issue, I've implemented some of the recommendation with reguards to "no ip redirects", "no ip unreachables" on all our SVIs. I found the document which describes the basic troubleshooting process on the 4500 but to still no avail.
I've attached the outputs of the "show platform health", "show proc cpu", "show spanning-tree summary totals".
I've also done a span of the traffic going to the CPU with wireshark and it's mostly UDP traffic going through. I do see some multicast traffic coming from our Call Managers.
Any thoughts on where else I could look for this strange issue.
