I have a simple network setup, ISP-> cisco router-> 3com switch-> End users/devices. I'm thinking I can safely turn off spanning tree as I don't see myself getting into a loop-back situation with this configuration. I have spanning-tree disabled at the switch, but the router seems to have it enabled according to packet analysis on the router lan port (maybe by default? as i dont see a source-bridge statement in my start/run configs). And I don't see an option in the SDM utility.
Ultimately I'd like to see the router stop generating all of these STP packets.
Can i just issue the following command to disable, or is there more to this situation?
no source-bridge spanning
and if so, would ...
... re-enable it if desired in the future?
Thanks for sharing your expertise.
