Configuring basic port parameters
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.
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
index port caused-by disabled-time
1 1/18 itself 00:13:30
2 1/19 vlan 12 00:13:30
3 1/20 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
Vlans not configured but use HW MAC: 1 10
alloc in-use avail get-fail limit get-mem size init
configuration pool 16 6 10 0 3712 6 15 16
linklist pool 16 10 6 0 3712 10 16 16
Displaying loop detection resource information
Use the show loop-detection resource command to display the hardware and software resource
information on loop detection.
PowerConnect# show loop-detection resource
Vlans configured loop-detection use 1 HW MAC
Vlans not configured but use HW MAC: 1 10
alloc in-use avail get-fail limit get-mem size init
configuration pool 16 6 10 0 3712 6 15 16
linklist pool 16 10 6 0 3712 10 16 16
