On the managed switches use features that immediately shut down a port when a BPDU is received (BPDU Guard) or when too many MAC addresses are learned (say more than 16 for your typical edge port). Make sure you are capturing syslogs and/or SNMP traps so you know when a port shuts down. _______________________________________________ bblisa mailing list [email protected] http://www.bblisa.org/mailman/listinfo/bblisa
