ESRP Commands
enable elsm auto-restart ports
enable elsm auto-restart ports <portlist>
Description
Enable Extreme Link Status Monitoring (ELSM) auto-restart for the specified ports.
Syntax Description
Default
Disabled.
Usage Guidelines
If you have ELSM automatic restart enabled and the port goes down, ELSM automatically brings up the
port if it receives the Hello packets from its neighbor.
If you do not have automatic restart enabled, the port goes through the Up, Down, Down-Wait process
once. When you first enable ELSM or if you reboot the switch, it goes through the process twice. After it
is done with the cycle (or cycles), the port enters the Down-Stuck state.
To enable automatic restart, use the following command:
enable elsm auto-restart ports <portlist>
To disable automatic restart, use the following command:
enable elsm auto-restart ports <portlist>
To get out of the Down-Stuck state and enter the Down state, you can use one of the following
commands:
clear elsm auto-restart ports <portlist>
enable elsm auto-restart ports <portlist>
Example
The following command enables ELSM automatic restart for ports 1-5 on the switch:
enable elsm auto-restart ports 1-5
