Trunk on Failure

I have a fiber loop that uses 3550's with no routing and about 20 vlans. There is a critical link at one location so I installed wireless. I am now going to trunk the VLANS across it if the fiber gets cut. I was going to keep it shutdown until needed but I figured I can leave it on because, wont STP stop the loops even if there are three paths? Also is there any kind of setting in STP that will allow me to specify that it will travel over the high speed fiber and if that goes down then go over the slower wireless?

HI Friend,

Yes STP will take care of the loop so will block the redundant connection.

Talking about load sharing between 2 trunk links is posible via per vlan port priority.

You can increase the priority of your vlans on your fiber trunk links and reduce the priority of the vlan on another trunk link which is via wireless so al the vlans will move out via fiber links and once it goes down all the vlans will start passing via wireless links.

Where is this priority setting?
