Note the following when configuring traffic mirroring:

■

The destination port to be configured cannot be a member port of an existing 
mirroring group, a fabric port (only the Switch 5500/5500G have this 
limitation), a member port of an aggregation group, an LACP enabled port, or 
an STP enabled port.

■

When you configure the destination port of traffic mirroring on a Switch 5500, 
if mirroring group 1 does not exist on the switch, the switch will automatically 
create local mirroring group 1 and add the destination port to the group; if 
mirroring group 1 already exists but is not a local mirroring group, your 
configuration of the destination port will fail.

■

On a Switch 4500, if you execute the monitor-port command on different 
ports to configure the destination port for the switch, the last configuration 
takes effect.
