  1. Upgrade the SBC application either using LSWU or Platform Manager.

  2. From the CLI command prompt, perform one of the steps below, depending on your configuration. For example, in SBC Core, set bond monitoring type to network-connect and leader election algorithm type to enhanced:

    > request system admin sbx1 setHaConfig bondMonitoring network-connect leaderElection enhanced

Verifying GRHA Mode

Accomplish the following step to verify GRHA mode:

> show table system haConfig 
                        LEADER     BOND
