Quick span tree question

Apr 27, 2010 2 Replies

I have an assumption that having 2 switches with single fiber trunk, there is no way for broadcast loops to form. If I add another trunk cable, then spanning tree kicks in. Correct?

Unless STP is turned off it still runs even if there is only one link. Of course all ports remain Forwarding.

I think most people leave STP running even if the network theoretically does not need it in order to protect the network from inadvertant creation of loops due to incorrect patching.

If I didn't need the bandwidth I would avoid port-channel on trunk links since it is possible to very easily break the network when adding/removing vlans to/from trunks.

If you need the bandwidth then of course go ahead:)
