Huawei MA5800 does not support active/standby mode, but only load sharing mode.
MA5800 has a distributed architecture. When two control boards like 100G bandwidth MPLA and 200G bandwidth MPLB are configured, the active and standby control boards carry services at the same time to effectively utilize the bandwidth of two control boards.
Each control board consists of the control module and the switching module.
- The control modules of two control boards always work in active/standby mode. If the control module of a control board is in the active state, this board is an active control board; if the control module of a control board is in the standby state, this board is a standby control board. When abnormalities such as faults or reset occur in the control module of the active control board, services on the active control board are automatically switched over to the control module of the standby control board, to ensure that the functions of control boards and relevant services are not interrupted.
- The switching modules of two control boards always work in load sharing mode, and the maximum switching bandwidth of the system is the maximum switching capacity of two control boards. When one control board is removed, or the switching module of one control board is faulty, traffic of the faulty control board is automatically switched over to the other control board. The maximum switching bandwidth of the system is the maximum switching capacity of one control board.
The MA5800 does not support active/standby mode, so it does not support:
- The protection between the active and standby control boards.
- The protection between the ports on the active and standby control boards.
- The protection between the aggregation groups on the active and standby control boards.
