I am in the process of cascading several 3560 switches together back to our 6500 core, and want the traffic to flow "up", rather than allowing spanning tree to choose the bottom switch to go "down" back to our core. I have modified both path cost and...
i agree with royalblues here. you actually cannot enable portfast on a trunk port, you can enable backbone fast though. which cuts through some of the learning stages of spanning tree.
also be sure to do a 'no shut' on the vlan1 interface. you also might be on another subnet, in which the switch does not know how to get there. to rectify this, in global config mode, set "ip default-gateway " also just looking on one of my 2950 swit...
I assume when you mean routing, you say layer 3. This is all layer 2, using the spanning tree protocol.Also, convergence is not my primary objective. I want to get all the traffic flowing the same direction back to the core, instead of allowing the s...
