Section 4 - LAN Configuration
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
General
mode the port is a member of a user selectable
set of VLANs. The port sends and receives data that is
tagged or untagged with a VLAN ID. If the data into the
port is untagged, it is assigned the defined PVID.
For example, if Port 3 is a General port with PVID 3, then
the untagged data into Port 3 will be assigned PVID 3. All
tagged data sent out of the port with the same PVID will
be untagged. This is mode is typically used with IP Phones
that have dual Ethernet ports. Data coming from phone
to the switch port on the router will be tagged. Data
passing through the phone from a connected device will
be untagged.
Note:
The DSR-150/150N do not support General mode due
to hardware limitations.
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.
