configure elrp-client inter-vlan-loop-detection

configure elrp-client inter-vlan-loop-detection [on | off]

Description

Turns on/off Extreme Loop Recovery Protocol (ELRP) inter-VLAN loop detection.

Syntax Description

inter-vlan-loop-detection ELRP detects loops between untagged ports on different VLANs on the same switch.
on Turns on Inter-VLAN loop detection. (Default)
off Turns off Inter-VLAN loop detection.

Default

Inter-VLAN loop detection is on by default.

Usage Guidelines

It is common in networks for you to accidentally inter-connect two different VLANs by looping together two untagged ports (one in each respective VLAN). This type of configuration results in an outage, and it is difficult for the average user to detect.

If desired, you can then include or exclude the inter-VLAN loops to be disabled using the configure elrp-client disable-ports [exclude | include] [ ports | eaps-ring-ports | remote-endpoints vxlan | inter-vlan-loop] command.

Example

The following example turns on Inter-VLAN loop detection:

# configure elrp-client inter-vlan-loop-detection on
