<p>An Ethernet interface protection method and a network side device are provided. The method includes: a network side device acquiring a backup route of a protected interface; establishing an active and standby relationship entry of the protected interface and the backup route; establishing FRR group information according to the active and standby relationship entry; judging whether direct route forwarding entry information exists on the protected interface according to the FRR group information; if the direct route forwarding entry information exists, then finding all direct route forwarding entry information on the protected interface according to index information of the protected interface in the FRR group information, and establishing an association relationship between direct routes and an FRR index of the FRR group information; and if the direct route forwarding entry information does not exist, then writing forwarding entry information corresponding to an FRR backup route and the direct route forwarding entry information into a hardware forwarding table. The method can reduce the time overhead of packet detection, thereby reducing the packet loss time and improving the expansibility and compatibility.</p> |
