I have two HP switches (#7 2900, #8 2910al) connected to each other via gigabit. Both switches also connect to a Cisco 2811 at 100 megabit. All three devices have STP enabled with their default options. I would like the link from the 2811 to #8 be blocked and the link from 7 to 8 active.
I don't want to play with the root bridge values unless absolutely necessary. From the HP manual it sounds like I should be able to set the path-code and / or priority on the #8's port that connects to the router. I'm not sure exactly what values I need; please assist.
