loopback-detection mode

Use the command to decide the loopback detection mode. To return to the

default settings, use the no form of this command.

loopback-detection mode {port-based | vlan-based}

no loopback-detection mode

Default The default mode is port-based.

Command Mode Configuration mode.

Usage Guideline If the detection mode is set to port-based means the switch determines loopback

based on port. If loop back happened, will treat the whole port as loop backed

port and block this port. LBD will send the CTP packets periodically per port.

On the other side, vlan-based mode makes switch will per port per VLAN send

the CTP packets periodically. This mode can detect loopback based on VLAN. If

switch detects loopback on a VLAN, LBD will only block the traffic which belongs

to this VLAN. Other VLANs' traffic should not be affected on this port.

Example This example shows how to choose the loopback detection operation mode.

You can verify your settings by entering the show loopback-detection

command.

Syntax Description

port-based In port-based mode, the port will enter the error disabled state when it detects

the loop.

vlan-based In VLAN-based mode, the port can’t process packers of the VLAN that detects

the loop.
