Buffer Misses on Cisco 2970 and 2950 switches

Hi,

I am seeing a lot of big buffer misses, some small buffer misses and medium buffer misses on our 2970 and 2950 switches. I'm seeing this on most of our switches (about 10 of them). I've searched the forum and docs and only found info relating to routers. Anybody know what these errors mean and how to troubleshoot them for switches? Thanks in advance.

One common reason for this in 2950 switches is due to flooded traffic. Plug in a sniffer in promiscous mode and check for any broadcast/multicast/unknown unicast flooded traffic.
