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.
And did you even try the command I give you? In the previous thread ---> Some of those are known to run IOS 10 - 12 The older 2900s don't support it from about 7 -8 years ago. Updates the IOS? If I paid a couple grand for a core switch i'd be calling Cisco!

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