When i do a sh int trunk there is a trunk port that is not showing up and I don't know why, it's a Catalyst 4500, other trunk ports show up, but for some reason I don't know of one trunk port does not show up?

Here is the trunk port config for the port that does not show up:
interface GigabitEthernet5/3
 switchport trunk native vlan 300
 switchport trunk allowed vlan 2-97,99-4094
 switchport mode trunk
 switchport nonegotiate
 udld port aggressive
 channel-group 1 mode active
 spanning-tree portfast disable

hi this port is bundled to a port channel it seems, you have to check if the other port is configured exactly the same and the port channel interface asswell. with the allowed vlan configured exactly the same on bouth ports of the port channel.

please let me see the output of your devices and some logs produced by your switch.
