Procedure
Step 1 Enable loop detection globally.
<Quidway> system-view
[Quidway] loop-detection enable
Step 2 Enable loop detection in a VLAN.
[Quidway] loop-detection enable vlan 200
Step 3 Enable loop detection control on an interface.
[Quidway] interface GigabitEthernet 1/0/0
[Quidway-GigabitEthernet1/0/0] stp disable
[Quidway-GigabitEthernet1/0/0] port hybrid pvid vlan 200
[Quidway-GigabitEthernet1/0/0] port hybrid untagged vlan 200
[Quidway-GigabitEthernet1/0/0] loop-detection mode port-shutdown
Step 4 Set the loop detection interval on the interface.
[Quidway] loop-detection interval-time 50
Step 5 Set the recovery time of a blocked interface.
[Quidway] interface GigabitEthernet 1/0/0
[Quidway-GigabitEthernet1/0/0] loop-detection recovery-time 20
Step 6 Verify the configuration.
GE 1/0/0 is automatically disabled when a loop is detected.
