Complete one of these tasks to configure the ADTRAN Operating System (AOS) Switch for port mirroring, either through the switch CLI or the switch web UI.

​
Configuration Through the CLI

To configure the device through the CLI
  1. Open a monitor session.
  2. Specify the port to be mirrored (the source port). 
    (config)#monitor session 1 source interface ethernet 0/<source_port>
  3. Specify the port that is going to mirror the traffic (the destination port). 
    (config)#monitor session 1 destination interface ethernet 0/<destination_port>
    Note: There can be only one monitor session. Therefore, the only available monitor session is “1.”
  4. Verify the configuration of the mirrored ports. 
    Switch#show monitor session all

​
Configuration Through the Web UI

To configure the device in the web UI
  1. Go to Utilities > Port Mirroring.
  2. Choose Destination Port and select the proper port from this menu.
  3. (Optional.) Select the No-Tag option so as not to tag virtual local area network (VLAN) traffic.
  4. Select the Source Port to mirror from the menu.
  5. Click Add.
    Note: If you want to add additional source ports to monitor, select another port from the Source Port menu and click Add.
  6. In the command-line interface (CLI), you can verify the configuration of the mirrored ports. 
    Switch#show monitor session all
