Perform a master/slave
switchover between the two
OLT ports in the fiber backup
group
port switch-over Optional
Up to two OLT ports can be added to one backup group. An OLT port can be added to only one
backup group at a time. The port added to the backup group earlier will be the master port, while
the other port will be the standby port.
Only one of the two OLT ports in a fiber backup group can be in the forwarding state.
After the second OLT port is added to a backup group, you need to manually synchronize the
configurations of the first OLT port and all the ONUs under it to the second OLT port. This ensures
normal service operation after a master/standby switchover.
