I have two WS-3750-24PS in a stack with two etherchannels against two Enterasys N3 with 802.1w. I read that the 3750 just support the 802.1w standard if the mst is configured, is that right?? Is there any other way to interconnect these devices avoiding loops??
That's right, the way Cisco supports standard 802.1w (as opposed to their, in regard to per VLAN support superior) rpvst+ is by configuring MST, but without regions.
I.e. you run it all in MST0.
