Figure B-20. How To Select a Local Exit Port
5. Use the Space bar to select the port to use for sending mirrored traffic to
a locally connected traffic analyzer or IDS. (The selected interface must
be a single port. It cannot be a trunk.) In this example, port D5 is selected
as the local exit port.
6. Highlight the Monitor field and use the Space bar to select the interfaces
to mirror:
Ports: Use for mirroring ports, or static trunks.
7. Use the down arrow key to move the cursor to the Action column for the
individual port interfaces and position the cursor at a port, or trunk you
want to mirror.
