Redundant Links to 3500 Series Switch

We have 2 3524-PWR clustered together with GigaStack. On each 3524, there is a gig link back to the same 6509 switch (otherwords - two links back to the same switch). I want the cluster command swithch gig link to forward and the other switch's gig gig link to block, if the first link fails, the second will take over, and then when the first link comes back online it to be the forwarding port once again. What settings for Spanning-Tree and UplinkFast would be best to accomplish this?

Re: Redundant Links to 3500 Series Switch

make the port cost on your primary link lower than

the secondary. I'd do it on the 6509. One of the two gigastack links should go into blocking automatically.

make the 6509 root for spanning tree.
