Re: local SPAN and promiscuous mode

It sounds like you're seeing unicast flooding. Try aligning the ARP and
mac-address table aging timers on your switch.

Hi,

I have enabled local span on a 6509 switch and discovered that unintended
unicast traffic are received on the destination port.

My understanding is that this will only happen in Hub not a switch. Am i
wrong on this? The capture was using wireshark with promiscuous mode on.

Session 3
---------
Type : Local Session
Source Ports :
   Both : Gi3/5-6
Destination Ports : Gi3/42

Egress SPAN Replication State:
Operational mode : Centralized
Configured mode : Centralized (default)
