disable elsm ports

disable elsm ports port_list


Disables the ELSM protocol for the specified ports.

Syntax Description

port_list Specifies the port or ports for which ELSM should be disabled.


The default is disabled.

Usage Guidelines

ELSM works between two connected ports, and each ELSM instance is based on a single port. When you disable ELSM on the specified ports, the ports no longer send ELSM hello messages to their peers and no longer maintain ELSM states.

When you enable ELSM on the specified ports, the ports participate in ELSM with their peers and begin exchanging ELSM hello messages. To enable ELSM, use the following command:

enable elsm ports port_list

For more information about ELSM, see the command enable elsm ports.


The following command disables ELSM for slot 2, ports 1-2 on the switch:

disable elsm ports 2:1-2:2


This command was first available in ExtremeXOS 11.4.
