Add two OLT ports of the same EPON board to a fiber backup group one after the other.
Perform a manual switchover between the two OLT ports. When the master port is shut down, the
slave port becomes the new master port.

Configuration procedure
# Create fiber backup group 1.
<Sysname> system-view
[Sysname] ftth
[Sysname-ftth] fiber-backup group 1
Create group 1 successfully.
# Add port OLT 3/0/1 and then OLT 3/0/2 to fiber backup group 1. Thus, OLT 3/0/1 works as the master
port and OLT 3/0/2 the slave port.
