Usage Guide
The preemption mode includes
forced, bandwidth and off
. In the
bandwidth
preemption mode, the
interface with high bandwidth has priority over other interfaces to transmit the data. In the
forced
preemption mode, the primary has priority over backup interfaces to transmit the data. No preemption
event occurs in the
off
preemption mode. By default, the preemption mode is off.
The preemption delay refers to the delay time of the link switchover after the restoration of the link
failure.
Configuration
Examples
The following example shows how to set the dual link backup, with fa 0/1 and fa 0/2 as the primary
interface and backup interface, set the bandwidth preemption mode and 40s preemption delay:
Ruijie(config)# interface fa 0/1
