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 page45.
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 page44.) 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-detection command.
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)
index port/vlan status # errdis sent-pkts recv-pkts
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 ?”
