However, BPDU Guard can be corrupted by unexpected cause. In this case, the edge 
port is blocked immediately and remains at this state until user recovers it. To prevent this 
problem, the hiD 6615 S223/S323 switch provides BPDU guard auto-recovery function. 
When an edge port is down for BPDU packet which came from other switch, the port is 
recovered automatically after configured time. 

To configure BPDU Guard auto-recovery, use the following command. 

Configures BPDU Guard auto-recovery on switch. 

 <10-1000000> 

Configures BPDU Guard auto-recovery-time. 

Bridge 

Disables BPDU Guard auto-recovery function. 

 

To recover a blocked port by manually, use the following command. 

stp bpdu-guard err-recovery 

 

Bridge

Although there is no double path in user’s equipment, loop can be caused by network en-
vironment and cable condition connected to equipment. To prevent this, the hiD 6615 
S223/S323 has self loop detection to perceive that outgoing packet is got back. Through 
the self loop detection, you can prevent packet, which comes back because it blocks the 
port.
