Configure the LACP System Identifier

In the following procedure, ports 0/1, 0/2, and 0/3 are part of the LA. Unless otherwise noted, you must run all of the commands in the following procedure on both switches.

1. Enable port channeling.

   SEFOS# configure terminal
   SEFOS(config)# set port-channel enable

2. Create the port channel (1 in this example).

   SEFOS(config)# interface port-channel 1
   SEFOS(config-if)# no shutdown
   SEFOS(config)# end

3. Configure the LACP system identifier.

   SEFOS(config)# lacp system-identifier 00:55:44:33:22:11
   SEFOS(config)# end

4. Review the etherchannel information to ensure that the port channel system identifier has been set.

   The output has been truncated for readability.

   SEFOS# show etherchannel detail
