11.3.27 Managing Port-Backup
11.3.27.1 Configuring Port-Backup Configuration
Two ports are associated for one group. Two ports are acted as active and backup ports. One of two
ports will be active at a one time. As configured active port is linkup, the backup port will be disabled.
Otherwise, if configured active port is link down, the configured backup port will be enabled. The
configured active has higher priority to become 'active', as two ports of a group are all link up before
group is enabled.
