    Verification

    Purpose

    The following verification section (with verification commands and sample output) can be used to confirm that MC-LAG Active/Active between the core and PODs has been configured correctly.

    Results

    1. Verify that ICCP is configured and is showing as Up.
      root@VDC-core-sw1-re0#run show iccp
      Redundancy Group Information for peer 192.168.168.5
        TCP Connection       : Established 
        Liveliness Detection : Up
      
      Backup liveness peer status: Up Redundancy Group ID Status 1 Up <<<< ICCP protocol is UP for RG ID 1>>>
      Client Application: l2ald_iccpd_client <<< L2 Forwarding joined the Redundancy group >>> Redundancy Group IDs Joined: 1
      Client Application: lacpd Redundancy Group IDs Joined: 1 <<<< redundancy group ID
    2. Verify that the ICL is configured with all VLANS and that the ICL is up. Verify that all VLANS configured on the MC-AE interfaces are properly allowed over the ICL link.
