Link Aggregation (LAG) question

Link Aggregation (LAG) question

I never setup LAG before on switch ports, so just to make sure, when I setup LAG, it have to be done on two switches right?  For example from switch A and B.

 

If I only setup LAG on switch A what happens?  My understanding is that LAG is used for redudency, load sharing, and higher bandwidth.

Correct.

If you connect two different systems, if you connect a switch using both (non-configured) ports, to this LAG - I'll promise a nightmare and mess on your LAN.
