3. Select the Channel and the associated port from the Sou r ce Port column
pull-down menu.
4. In the Mirror Port column pull-down menu, select the port to which you
want to mirror traffic.
Both the source port and mirror port must either:
—Be on the same VLAN and have the same VLAN binding
or
—Have VLAN binding set to bind to all
*Note: The source port and the mirror port must be different
physical ports.
5. In the Direction/Filter column, select the direction of traffic that you
want to mirror and the filter that you w ant to set up, if any.
You can set up a MAC address filter to monitor only traffic with a
specific source MAC address or destination MAC address.

• 13–24 — any 1 port or the entire
range.
• 25–36 — any 1 port or the entire
range.
• 37–48 — any 1 port or the entire
range.

channel 1 and port 13 on channel 2
simultaneously. However, you cannot
mirror port 1 on channel 1 and port 2 on
channel 2 simultaneously.
