After completing step 5b, the switch begins mirroring traffic to the remote
destination for the configured session.
Local Mirroring (Mirroring Source and Destination on the Same
Switch).
1. Determine the session identity and local destination port:
• session number (1-4) and (optional) alphanumeric name
• exit port (This can be any port on the switch except a mirroring source
port.)
2. Use mirror < 1 - 4 > [ name < name-str >] port < port-# > to configure the session.
3. Determine the source interface(s) to monitor (VLAN, port, mesh) and the
traffic selection method:
– in, out, or both
– inbound ACL
4. Use the monitor command to assign the source interface(s) to the session.
After completing step 4, the switch begins mirroring traffic to the configured
exit port.
The next two sections provide quick references to the command syntax
options for executing the above general steps.
