This is a new one on me. We have about 200 2950's deployed as aggregate switches on the network. I have a client on the network now that has 2 VLAN's that they are using for Multicast traffic. One VLAN accounts for about 6Mbps and the other about 40. Now that these streams are up and running on multiple video stations I can no longer do anything management related to the switches themselves without major latency. For example if I try to ping one of the management addresses of one of the 2950's I get either a timeout or about 2~3k ms response times. Users in various VLAN's on these switches are 100% operational and they are not experiencing any latency on the network, the slowness only pertains to management of the switches themselves. Further the CPUs are only at about 15%. When the 2 VLANs carrying the multicast traffic are pruned out of the trunks to the 2950's the switches respond to pings in under 1ms and ssh/telnet sessions no longer linger between character echoes. My core 6509s are unaffected. Any guesses?
