ACTIVE AND STANDBY CHANGEOVER METHOD, APPARATUS, DEVICE, AND SYSTEM FOR NETWORK DEVICE

摘要

A main and standby switchover method, apparatus, device, and system for a network device relate to the technical field of wireless networks. The method includes: receiving an interrupt signal indicating that a switchover needs to be performed for main and standby GE ports; performing a switching operation of the main and standby GE ports, setting the main GE port in a blocked state, and in the blocked state, the main GE port only forwarding a bridge protocol data unit (BPDU) message, and stopping learning a MAC address; and enabling the standby GE port, setting the standby GE port in a forwarding state, and in the forwarding state, the standby GE port forwarding messages of all types, and learning the MAC address. By using the foregoing method, rapid completion of main and standby GE ports can be implemented, and a requirement of hand-in-hand double-link protection of an electric power EPON standard is met.
