I am running the latest version of 12.2(55)SE6 on the catalyst and I am looking for this command "lacp rate fast" but it is not there:
Enter configuration commands, one per line. End with CNTL/Z.
port-priority LACP priority on this interface
According to this link, it is supposed to work: https://supportforums.cisco.com/thread/2169447
Am I missing something?
