protection holdoff
Use protection holdoff to specify the holdoff time when a working tunnel failure is detected.
Use undo protection holdoff to restore the default.
Syntax
protection holdoff holdoff-time
undo protection holdoff
Default
The holdoff time is 0 seconds. When the working tunnel fails, traffic is immediately switched from the
working tunnel to the protection tunnel.
Views
Tunnel bundle interface view
Predefined user roles
network-admin
Parameters
holdoff-time: Specifies the holdoff time in the range of 0 to 10 seconds.
Usage guidelines
When the working tunnel fails, the tunnel bundle interface waits for the holdoff time to switch traffic from
the working tunnel to the protection tunnel.
To avoid repeated switchover due to the network instability, traffic is not switched from the working tunnel
to the protection tunnel if the working tunnel recovers within the holdoff time.
You can execute this command only after MPLS protection switching is enabled by using the mpls
protection command.
Examples
# Set the holdoff time to 3 seconds for Tunnel-Bundle 2.
<Sysname> system-view
[Sysname] interface tunnel-bundle 2 protection onetoone
[Sysname-tunnel-bundle2] protection holdoff 3
