Brocade Communications Systems 6650 manual Displaying loop detection resource information

2 Basic port parameter configuration

The following command displays the current disabled ports, including the cause and the time.

Brocade# show loop-detection disable Number of err-disabled ports: 2

You can re-enable err-disable ports one by one by "disable" then "enable" under interface config, re-enable all by "clear loop-detect", or configure "errdisable recovery cause loop-detection" for automatic recovery

index	port	caused-by		disabled-time
1	1/1/1	vlan	1	00:00:10
2	1/1/9	vlan	1	00:00:10

This example shows the disabled ports, the cause, and the time the port was disabled. If loop-detection is configured on a physical port, the disable cause will show “itself”. For VLANs configured for loop-detection, the cause will be a VLAN.

The following command shows the hardware and software resources being used by the loop-detection feature.

Vlans configured loop-detection use 1 HW MAC

Vlans not configured but use HW MAC: 1 10
