Usage Guidelines

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.

Example

# Display information about a working tunnel with the tunnel ID of 100 and its protection tunnel.

<HUAWEI> display mpls te protection tunnel 100
