debug loop-detect

Allows the RUCKUS devices to detect loops using the RUCKUS Port Loop Detection (PLD) protocol and disable a port that is on the receiving end of a loop. The loop is detected by sending Bridge Packet Data Unit (BPDU) test packets.
Syntax
debug loop-detect
no debug loop-detect
Usage Guidelines
This command initiates debugging the loop detection.
Examples
Note: Execute the command prior to configuring the modes.

The following example shows how to configure loop detection of a single port in strict mode. 

device# debug loop-detect
Configure loop-detection strict mode on port 1/1/25 :
device(config-if-e1000-1/1/25)# loop-detection

When there is loop detection activity in the device, the debug information regarding loop detection is displayed on the console. The following example shows the output when the port goes into a disabled state because of loop detection (strict mode). 

insert_disable primary 1/1/25, vlan=4096
Loop-detection: port 1/1/25 (vlan=1), put into errdisable state

The following example shows how to configure loop detection in a VLAN in loose mode. 

Configure loop-detection loose mode on port vlan 2 :
device(config-vlan-2)# loop-detection
device(config-vlan-2)# insert_disable primary 1/1/31, vlan=2

The following output is displayed after the configuration. 

Loop-detection: port 1/1/31 (vlan=2), put into errdisable state
insert_disable primary 1/1/32, vlan=2
Loop-detection: port 1/1/32 (vlan=2), put into errdisable state
