Support Tips: Access Port vs Trunk Port
-
Access Port
-
Allows one untagged VLAN to pass through it
-
Access ports are typically used for “edge” devices such as computers because of their lack of ability to handle tagged traffic
-
Any tagged traffic sent to or from the interface will be dropped
-
Can be used to isolate a network segment such as a DMZ
Trunk Port
-
Referring to a VLAN trunk rather than link aggregation
-
A trunk port allows one untagged and all tagged VLANs to pass through it as long as they are added to the port configuration
-
Trunk ports are typically used for connections between switches to allow for multiple VLANs to communicate but can be used for any device that can manage multiple VLANs and include a VLAN tag on the frames
-
The untagged traffic will be sent on the native VLAN

Can be but doesn't have to be.
Many traditional PBX vendors really push their clients to put the phones on their own VLANs, and often the client will hang the local computer off the phone. The phone in this case fully understands VLANs and puts it's traffic on a tagged VLAN while putting the PC on the untagged network.
