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.
