i found this which may be of use

So, as it turns out, it's a 2900XL, which does not support 802.3ad or
LACP at all, just a proprietary port channeling for switch interconnect
as far as I can tell.
I suppose that leaves me with just using pure software (for now, I have
an 8 port Intel Pro 100 at home that I'll look at...), but I'm unable to
get the increased throughput using mode=0. I did notice, however, while
I was on the switch console it kept complaining about the interfaces
flapping and re-learning addresses. My network guy here at work said
that it was bad and either the switch or the bond(s) is misconfigured
somewhere. Any hints as to where and or what kinds of things I should
be looking at?

Hi!
LACP is a part of 802.3ad.
Cisco 2900XL supports 802.1Q, ISL, EtherChannel, LACP, etc. Depending
on the age of the switch and the version and category of IOS used, the
LACP support may be there. Cisco has many IOS versions for the hardware
you have.

As for protocols support, it's hard to beat Cisco.
