Redundancy backup

مدعوم

MPUs are mandatory for switches. You can configure one or two MPUs for each switch. The MPU can be installed in either MPU slot of a switch. An MPU consists of the control plane, management plane, and data forwarding plane. When two MPUs are installed, the two MPUs work in hot standby mode on the control and management planes and work in load balancing mode on the data forwarding plane. MPUs monitor each other. When the active MPU is faulty, the standby MPU is automatically switched to be the active MPU to ensure service continuity.
