Trunking between 2 6509's and multiple 4506's

[bdelano]

I have 2 cat6509 distro switches with multiple 4506 access switches. I have redundant links from the 4506's to the 6509's. Cant seem to get both 6509's to trunk all vlans across all ports.

What are the trunk settings you have set on either ends ?
