ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
Commands for Status Monitoring and Statistics
If you try to enable ELSM on a port that is already configured as a mirrored port, the switch displays
messages similar to the following:
Stand-alone switch
●
Cannot enable ELSM on port 1. Port is configured as mirror monitor port
Modular switch
●
Cannot enable ELSM on port 1:1. Port is configured as mirror monitor port
Configuration failed on backup MSM, command execution aborted!
Configuring the Hello Timer Interval. ELSM ports use hello messages to communicate information about
the health of the network to its peer port. You can also configure the interval by which the ELSM-
enabled ports sends hello messages. For more information about configuring the hello interval, see the
command
configure elsm ports hellotime
Disabling ELSM. 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. To disable ELSM, use the following
command:
disable elsm ports <portlist>
Example
The following command enables ELSM for slot 2, ports 1-2 on the switch:
enable elsm ports 2:1-2:2
