Access and Trunk Port Communication - SNMP

[mparham6]

I have two ports configured on a switch, one being an access port for VLAN 10, the other being a trunk port.  Should two hosts (one connected to the access port, the other connected to the trunk port) be able to talk to each other?  Specifically via an SNMP tool?  I'm unable to establish the communication with this configuration until I give the trunk port a "switchport trunk allowed vlan 10" command.  Why is this necessary?  Shouldn't it work without this config since a trunk port should be allowing all VLAN traffic through?

There is much we do not know that might have some impact on answering this question. What kind of switch is this? What version of code is it running? Exactly how was the trunk port configured? What kind of device is connected to the trunk port? Is it configured to process tagged frames? It would be helpful if you could post the output of show interface trunk from before you made the config change and after you made the config change?
