PC: RSTP + LAG

I'm reading up on how to enable Rapid Spanning-Tree on our core PowerConnects (3248s I believe).

Is it really as simple as typing:

# configure
(config)# spanning-tree
(config)# spanning-tree mode rstp
(config-if)# exit
(config)# exit

?

Also, currently each switch pair has a LAG/LACP two-port channel to it's partner switch. Will that affect the spanning-tree configuration in any special way?
