OLT（eth0/9 0 1）—–(g0/0/25-26)SW

Problem Description

The OLT Ports 0/9/0 and 0/9/1 are uplink, now the customer wants inter-board protection that two SCUN control boards working in active/standby mode.

Problem Analysis

When configuring inter-board protection, the system automatically detects the control board on which the optical port is used. Then, the system uses the control board whose optical port is connected with the optical fiber for upstream transmission. In a remote upgrade in such a scenario, the control boards need to be reset and therefore inter-board protection can be configured to facilitate the upgrade. The configurations are as follows:

huawei(config)#protect-group
{ pgid<U><0,63>|protect-target<K> }:protect-target
{ as-mainboard-lag<K>|as-mainboard-port<K>|as-mainboard<K>|epon-uni-port<K>|eth-
nni-lag-member<K>|eth-nni-port<K>|gpon-uni-port<K> }:as-mainboard
{ workmode<K> }:workmode
{ portstate<K> }:portstate
  Command:
          protect-group protect-target as-mainboard workmode portstate
huawei(protect-group-0)#protect-group member board 0/9

  Command:

huawei(protect-group-0)#protect-group member board 0/10 role protect
huawei(protect-group-0)#protect-group enable

Suggestion

suggest configuring protect-group on different OLT as dual-homing type-B rather than Two Control Boards in one OLT.
