I enabled CDP on a **trunk** port of a cat6509, I also enabled the
other end (cisco 3750) with cdp enable on all the interfaces,

sh cdp n on both are still empty? why? I waited good 10 min. still
nothing.

3750 output
-----------
3750#sh cdp traffic

Can you do a "show switchport trunk int x/y", "show int x/y" and
"show cdp interface x/y" in both switches and send it?

also the configuration of both switch port's will be helpfull.
