Two GS108T's

[Chaos6]

I've been using an original GS108T for a little over two years now as the primary switch for the gigabit ethernet in our house. It has served me well so far. I recently finished our basement though, and have added a few more ports to the configuration for the house. I now need 11 or 12 ports. I purchased a GS108T-200NAS and planned to use link aggregation between the two switches to bond them together with two ports. However, I'm having problems with loops whenever I connect more than one port together. Is the GS108T only good for 802.3ad with a NAS? Am I missing a step in setting up link aggregation between the two switches? Is there something I need to do to enable spanning tree support?

Any help would be greatly appreciated. Thanks!

Set your LAGs up before you connect the ports together.

I used these settings.

Thanks Tim, that did the trick. I was thrown off originally because the switch wouldn't let me set up the LAG group when I had anything connected to one of the ports that was going to be in the group. After disconnecting the switches from each other completely and setting up the groups while they were separated, everything worked great when I hooked them back up.
