Brocade Communications Systems 6650 manual Specifying the recovery time interval

Basic port parameter configuration 2

Brocade(config)# errdisable recovery cause loop-detection

The above command will cause the Brocade ICX 6650 device to automatically re-enable ports that were disabled because of a loop detection. By default, the device will wait 300 seconds before re-enabling the ports. You can optionally change this interval to a value from 10 to 65535 seconds. Refer to “Specifying the recovery time interval” on page 45.

Syntax: [no] errdisable recovery cause loop-detection

Use the [no] form of the command to disable this feature.

Specifying the recovery time interval

The recovery time interval specifies the number of seconds the Brocade ICX 6650 device will wait before automatically re-enabling ports that were disabled because of a loop detection. (Refer to “Configuring the device to automatically re-enable ports” on page 44.) By default, the device will wait 300 seconds. To change the recovery time interval, enter a command such as the following.

Brocade(config)# errdisable recovery interval 120

The above command configures the device to wait 120 seconds (2 minutes) before re-enabling the ports.

To revert back to the default recovery time interval of 300 seconds (5 minutes), enter one of the following commands.

Brocade(config)# errdisable recovery interval 300

OR

Brocade(config)# no errdisable recovery interval 120

Syntax: [no] errdisable recovery interval <seconds>

where <seconds> is a number from 10 to 65535.

Clearing loop-detection

To clear loop detection statistics and re-enable all ports that are in Err-Disable state because of a loop detection, enter the clear loop-detectioncommand.

Brocade# clear loop-detection

Displaying loop-detection information

Use the show loop-detection status command to display loop detection status, as shown.

Brocade# show loop-detection status
loop detection packets interval: 10 (unit 0.1 sec)					sent-pkts recv-pkts
index	port/vlan	status		# errdis
1	vlan1	0	errdis port	0	452	0
2	vlan2	0	errdis port	0	34	0
3	vlan3	0	errdis port	0	32	0
4	vlan4	0	errdis port	0	30	0
5	vlan5	0	errdis port	0	29	0

If a port is errdisabled in Strict mode, it shows “ERR-DISABLE by itself”. If it is errdisabled due to its associated vlan, it shows “ERR-DISABLE by vlan ?”
