Trunking switches cannot see one another?

Evening ladies and gents,
I've got a 2950 and a 3500 series switch that I'm labbing up a bit of VTP on. I've hard coded the ports that the crossover cable currently is connected to as trunks and both interfaces show up/up. My problem is that after configuring one switch as a client and the other as a server-my client switch would not update. I did a show cdp neighbor, only to find that neither switch has the other show in it's neighbor table. I dont have any redundant links on the switches, and a show spanning-tree shows both ports in forwarding mode.
Any ideas?

The 3500 supports ISL and 802.1Q -- with ISL the default. What did you set as the trunk encapsulation?:mike: Cisco Certifications -- Collect the Entire Set! -
