Quick Link Aggregation on 3750 Question

I am looking to configure LACP on 3750 and wondering if there are any special considerations I should be aware of like minimum IOS level or something like that?

Will rate posts.

Thanks!

Any recent IOS should be fine. Have a look at the config guide to see the configuration restrictions/guidelines -

Hello Michael,

I haven't checked but I think that you have a 12.2(25)Sxy or better you should be fine.

some older IOS versions needed some more commands to define the lacp system-id and channel-protocol command in interface config, but lacp has been introduced some years ago.

>> 12.1(14)EA1

The active and passive keywords were added.

= lacp

see

so you should be fine unless you IOS is older then 12.1(14)EA1

Hope to help

Giuseppe
