Etherchannel - which mode should I use?

Discussion in 'Cisco' started by Adam Przestroga, Nov 28, 2009.

  1. Hi all,

    I am wondering which etherchannel mode should I use and why? From what I
    can see Etherchannel can be used across Cisco 3750 stacks as long as the
    stack runs on IOS 12.2(25)SE or newer and one uses LACP, but if I am
    reading this correctly below two should work:

    channel-group [#] mode on (disables PAgP, enables LACP)
    and
    channel-group [#] mode active (use LACP in an active mode, it will start
    to send LACP packets)

    If so, which one should I use and what are the pros and cos of both?
    Could someone clarify this for me?

    Thanks a lot.

    Six of one, half-dozen of the other. Both work just fine, the only real
    difference is that LACP is an IEEE standard and PAgP is Cisco proprietary.
