
In Access mode the port is a member of a single VLAN (and only one). All
data going into and out of the port is untagged. Traffic through a port in
access mode looks like any other Ethernet frame.

In Trunk mode the port is a member of a user selectable set of VLANs. All
data going into and out of the port is tagged. Untagged coming into the port
is not forwarded, except for the default VLAN with PVID =1, which is
untagged. Trunk ports multiplex traffic for multiple VLANs over the same
physical link.

Select PVID for the port when the General mode is selected.

Configured VLAN memberships will be displayed on the VLAN
Membership Configuration for the por t. By selecting one more VLAN
membership options for a General or Trunk port, traffic can be routed
between the selected VLAN membership IDs
