CLI Reference REUP Configuration Commands
switchport backup interface interface-id preemption
Use this command to configure the REUP link preemption function.
switchport backup interface interface-id preemption mode { forced | bandwidth | off }
switchport backup interface interface-id preemption delay delay-time
no switchport backup interface interface-id preemption delay
Parameter
description
Parameter Description
interface-id The interface id of the backup link.
delay-time The preemption delay time.
Default
The preemption function is disabled by default.
The default preemption delay time is 35s.
Command
mode Interface configuration mode.
Usage
guidelines
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 occurrs in the off preemption
mode. By default, the preemption mode is off.
The preemption delay refers to the delay time of the link reswitch after
the restoration of the link failure.
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
Ruijie(config-if)# switchport backup interface fa 0/2
preemption mode bandwitdh
Ruijie(config-if)# switchport backup interface fa 0/2
preemption delay 40
