Addr flap on 3500xl

I have tons of syslog msg's from a site similar to above. The site has a non cisco wireless installed that creates a moving smorgasbord of mac addresses.

I would prefer not to get these msg's on the management console.. how do i kill just this specific syslog msg without killing all others?

For obvious reasons, I do not want to turn off level 2 syslog traffic and higher. I would prefer to just kill this one type of syslog traffic.

Any suggestions?

Hi

I think there is a loop in u r network.instead of thinking to disable these messgs first try to figure out what is the cause of this loop.

Thanks

Can you trace and find out what is conencted to the gigabit ehternet interfaces.

Issue sh mac-address-table aging-time and see whether you see a vlaue of 15 associated with any VLANS

I have had this problem earlier which was traced to a server configured with NLB but not using it.
