Dell PowerConnect B-FCXs Configuration Manual page 97

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.
PowerConnect# 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

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
