Etherchannel - which mode should I use?

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.
