Steve, Saku, thanks for you continued interest in my problem :)

The problem is: I am making the assumption that network performance on the LAN could be sub-optimal due to frequent unicast floods (i.e. switches are flooding all ports with unicast frames because it does not have the destination MAC address in its table); and I would like to verify whether this is the case or not. So before even blocking or rate-limiting, I'd like to 1) assess whether those floods are happening or not 2) quantify them to understand whether they are at a reasonable level or not 3) locate their source so that I can take the required action (maybe adjusting ARP timers on redundant routers, rate-limiting, blocking, etc.). Is there a way to do this? We are talking about 2970 running "c2970-lanbase-mz.122-25.SEB4". Thanks for your input Vincent PS: what is PFC?... _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
