"lacp rate fast" in Catalyst 3750?

Unanswered Question

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:

lab-c3750#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

lab-c3750(config)#interface g1/0/5

lab-c3750(config-if)#lacp ?

  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?

I realize this thread is 3 years old, however I had this same issue, and hope this information will help somebody else.

The 3750 only supports slow LACP. The rate for this is every 30 seconds.

The 6500 series will support a "Fast" or 1 second LACP rate.
