Configure the LACP Port Identifier

In the following procedure, ports 0/1, 0/2, and 0/3 are part of the LA.

  1. On switch A, review the port state behavior for the default port identifier.
    SEFOS# show etherchannel 1 detail

    The following output has been truncated for readability.

    ...
                     LACP Port   Admin  Oper   Port    Port
    Port     State   Priority    Key    Key    Number  State
    ---------------------------------------------------------------------
    Ex0/1    Bundle  128         1      1      0x1     0xbe
    Ex0/2    Bundle  128         1      1      0x2     0xbe
    Ex0/3    Standby 128         1      1      0x3     0xa2
    ...

    Note - Before you configure the LACP port identifier, note that the extreme-ethernet port, 0/3, in switch A and switch B are standby ports.


  2. For port 0/3 in switch A, configure the port identifier as 1.
    SEFOS(config)# interface extreme-ethernet 0/3
    SEFOS(config-if)# lacp port-identifier 1
  3. Review the configuration information.

    Note - After you configure the LACP port identifier, note that the extreme-ethernet port, 0/3, in switch A is brought up in the bundle state.
