Configuring a global loop detection interval
The loop detection interval specifies how often a test packet is sent on a port. When loop detection
is enabled, the loop detection time unit is 0.1 second, with a default of 10 (one second). The range
is from 1 (one tenth of a second) to 100 (10 seconds). You can use the show loop-detection status
command to view the loop detection interval.
To configure the global loop detection interval, enter a command similar to the following.
PowerConnect(config)# loop-detection-interval 50
This command sets the loop-detection interval to 5 seconds (50 x 0.1).
To revert to the default global loop detection interval of 10, enter one of the following.
PowerConnect(config)# loop-detection-interval 10
OR
PowerConnect(config)# no loop-detection-interval 50
Syntax: [no] loop-detection-interval number
where number is a value from 1 to 100. The system multiplies your entry by 0.1 to calculate the
interval at which test packets will be sent.
Configuring the device to automatically re-enable ports
To configure the device to automatically re-enable ports that were disabled because of a loop
detection, enter the following command.
PowerConnect(config)# errdisable recovery cause loop-detection
The above command will cause the 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 35.
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 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 35.) By default, the device will
wait 300 seconds. To change the recovery time interval, enter a command such as the following.
PowerConnect(config)# errdisable recovery interval 120
This command configures the device to wait 120 seconds (2 minutes) before re-enabling the ports.
To revert to the default recovery time interval of 300 seconds (5 minutes), enter one of the
following commands.
PowerConnect(config)# errdisable recovery interval 300
OR
PowerConnect(config)# no errdisable recovery interval 120
