Usage Guidelines

Usage Scenario

Automatic protection switching (APS) enables nodes on both ends of a tunnel to switch and restore traffic if a fault occurs, implementing uninterrupted traffic transmission.

If a fault occurs on a working tunnel in a tunnel protection group, APS switches services from the working tunnel to a protection tunnel. After the working tunnel recovers, APS switches services back to the working tunnel if the retrieve mode is enabled for the protection group.

The display mpls te protection tunnel command can be used to display information about a specified tunnel protection group. The following parameters can be specified to display various types of information:

If the ID or tunnel interface of the working tunnel is specified, information about the working tunnel and its protection tunnel is displayed.
If the ID or tunnel interface of a protection tunnel is specified, information about the protection tunnel and all its protected working tunnels is displayed.

Precautions

Only the NetEngine 8000 F1A supports this command.

Example

The actual command output varies according to the device. The command output here is only an example.
