Configuring basic port parameters
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 following command.
TurboIron#clear loop-detection
Displaying loop-detection information
Use the show loop-detection status command to display loop detection status, as shown.
TurboIron#show loop-detection status
loop detection packets interval: 10 (unit 0.1 sec)
Number of err-disabled ports: 3
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/vlan status #errdis sent-pkts recv-pkts
1 13 untag, LEARNING 0 0 0
2 15 untag, BLOCKING 0 0 0
3 17 untag, DISABLED 0 0 0
4 18 ERR-DISABLE by itself 1 6 1
5 19 ERR-DISABLE by vlan 12 0 0 0
6 vlan12 2 ERR-DISABLE ports 2 24 2
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 ?”
The following command displays the current disabled ports, including the cause and the time.
TurboIron#show loop-detection disable
Number of err-disabled ports: 3
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 18 itself 00:13:30
2 19 vlan 12 00:13:30
3 20 vlan 12 00:13:30
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
