Troubleshooting an Aggregated Ethernet Interface



Description: The show interfaces terse command shows that the LAG is down.


Check the following:

  • Verify that there is no configuration mismatch.

  • Verify that all member ports are up.

  • Verify that a LAG is part of family ethernet-switching (Layer 2 LAG) or family inet (Layer 3 LAG).


    Layer 2 LAGs are not supported on OCX Series switches.

  • Verify that the LAG member is connected to the correct LAG at the other end.

  • Verify that the LAG members belong to the same switch.
