Too hard? It's on by default.

And if you want 802.1w rapid spanning tree then it's one command "spanning-tree mode rapid-pvst".

But here's your etherchannel commands.


int range g0/1 -4
 shut
 switchport
 switchport trunk encap dot1q
 switchport mode trunk
 channel-protocol lacp
 channel-group # mode active
 no shut

Dont forget to specify your Spanning Tree Root Bridge either.

Obviously the vlans need to reflect your network. From your Diagram, I suggest your 3750 Stack is set as the root.

RSTP is probably a better solution due to the quicker reconvergence.

If all the devices support it, I would use RSTP.
