ELSM Configuration Example
The following example configures ELSM on two ports connected directly to each other and assumes the following:

Note
In the following sample configurations, any lines marked (Default) represent default settings and do not need to be explicitly configured.Switch A Configuration
- ELSM-enabled port—Port 1
- Hello timer—2 seconds
- Hello threshold—2 hello messages
enable elsm ports 1 configure elsm ports 1 hellotime 2 configure elsm ports 1 hold-threshold 2 (Default)
Switch B Configuration
- ELSM-enabled port—Slot 2, port 1
- Hello timer—2 seconds
- Hello threshold—2 hello messages
enable elsm ports 2:1 configure elsm ports 2:1 hellotime 2 configure elsm ports 2:1 hold-threshold 2 (Default)
After you enable ELSM on the ports, the peers exchange hello messages with each other as displayed in Extreme Networks Switches with ELSM-Enabled Ports Exchanging Hello Messages.

To configure ELSM with LAG, enable ELSM on each port member of the LAG, as shown in the following example:
enable sharing 7 grouping 7-9, 41 algorith address-based L2 enable elsm port 7 enable elsm port 8 enable elsm port 9 enable elsm port 41 # sh elsm Port ELSM State Hello Time ==== ========== ========== 7 Up 1 (secs) 8 Down 1 (secs) 9 Down 1 (secs) 41 Up 1 (secs)
