I'd like to know if i can be able to enable lag on the controller but termite it on 2 different switches? i.e. i have 2 ports on the controller, i connect 1 port on switch1 int g1/5 and connect port on switch3 port 1/10?

How can i do this? as i need to configure etherchannel right?

No, the ports have to be connected to the same switch. Reason being you have to setup a port-channel on the switch for those ports. The only exception to spanning multiple switches is if you have 3750's in a stacked configuration.

Thanks for yr feedback.

i'd like to know then, which method can i use for redundancy? can i connect the 2 ports into different switches without lag (would that provide me with redundancy?)

If you don't use LAG you could connect the ports between different switches.

Wouldn't this depend on the controller?

if it is a 4402, wouldn't you want both ports on the same switch due to the npu on the controller that is shared between ports?
