ExtremeWare XOS 11.5 Command Reference Guide
628
disable elsm ports auto-restart
disable elsm ports <portlist> auto-restart
Description
Disable ELSM automatic restart for the specified ports.
Syntax Description
Default
The default is enabled.
Usage Guidelines
If you disable ELSM automatic restart, the ELSM-enabled port can transition between the following
states multiple times: Up, Down, and Down-Wait. When the number of state transitions is greater than
or equal to the sticky threshold, the port enters and remains in the Down-Stuck state.
The ELSM sticky threshold specifies the number of times a port can transition between the Up and
Down states. The sticky threshold is not user-configurable and has a default value of 1. That means a
port can transition only one time from the Up state to the Down state. If the port attempts a subsequent
transition from the Up state to the Down state, the port enters the Down-Stuck state.
If the port enters the Down-Stuck state, you can clear the stuck state and have the port enter the Down
state by using one of the following commands:
clear elsm ports <portlist> auto-restart
enable elsm ports <portlist> auto-restart
If you use the
enable elsm ports <portlist> auto-restart
command, automatic restart is always
enabled; you do not have to use the
clear elsm ports <portlist> auto-restart
command to clear
the stuck state.
Enabling Automatic Restart.
To enable ELSM automatic restart, you must explicitly configure this
behavior on each ELSM-enabled port. If you enable ELSM automatic restart and an ELSM-enabled port
goes down, ELSM bypasses the Down-Stuck state and automatically transitions the down port to the
Down state, regardless of the number of times the port goes up and down.
To enable automatic restart, use the following command:
enable elsm ports <portlist> auto-restart
If you configure automatic restart on one port, Extreme Networks recommends that you use the same
configuration on its peer port.
portlist
Specifies the port or ports for which ELSM auto-restart is being disabled.
