Tunnel bundle interface view
Predefined user roles

Parameters
clear: Cancels the executed switching command.
force: Forces traffic to travel on the protection tunnel.
lock: Always uses the working tunnel to forward traffic.
manual: Switches data from the working tunnel to the protection tunnel. If the protection tunnel fails,
traffic switching is not performed.
Usage guidelines
The following shows the protection switching triggers in the descending order of priority:
• Clear
• Lockout of protection
• Forced switch
• Signal fail on the protection tunnel—The signaling protocol detected a failure on the protection
tunnel.
• Signal fail on the working tunnel—The signaling protocol detected a failure on the working tunnel.
• Clear signal fail—The signaling protocol detected that the working or protection tunnel has
recovered.
• Manual switch
If multiple triggers exist, the one with the highest priority determines the tunnel for traffic forwarding.
Before configuring this command, you must enable MPLS protection switching by using the mpls
protection command.
If you execute this command multiple times to specify multiple externally configured switching actions, the
action with higher priority overwrites the one with lower priority. To modify an externally configured
switching action to one with lower priority, you must first execute the clear command to remove the former
configuration.
Examples
# On Tunnel-Bundle 2, force traffic to travel on the protection tunnel.
<Sysname> system-view
[Sysname] interface tunnel-bundle 2 protection oneplusone
