PID-V: VLAN Priority-Voice
 VLAN Link Type (AU and SU) – Defines the link type, which
actually defines the functionality of the VLAN-aware capability of
the unit.
Available options are: Hybrid Link, Trunk Link and Access Link
(Access Link is available only in SUs).
 The default selection is Hybrid Link.
 Access Link (SU only) – Transfers frames while
tagging/untagging them because all devices connected to it
are VLAN-unaware. Thus, the unit cannot transfer tagged
frames.
The following table summarizes the functionality of the
data port for an access link.

Legend: VID-D: VLAN ID-Data
PID-D: VLAN Priority-Data
 Trunk Link – Transfers only tagged frames, because all
devices connected to it are VLAN-aware:
Only tagged data frames received on Ethernet or wireless
link ports are forwarded.
Transmit Tag Insert VID-M, PID-M If VID-M = 65535 and Voice Priority
Tag option are enabled, Tag insert
VID=0, PID-V.
If VID-M not equal to 65535, insert
VID-M and PID-V
Action Data Port (SU)
Accept from Ethernet Untagged frames
Accept from Wireless Tagged frames, matching VID-D
Tag Insert VID-D, PID-D (to wireless)
Tag Remove Yes (to Ethernet)
WARNING:
It is not recommended to configure a unit as a Trunk Link with
VLAN ID - Management (or VLAN ID - Voice & Management) of 65535, as it
will not forward any ‘NO VLAN’ management frames to its other port. It will be
impossible to manage devices connected behind the unit that are also
configured with ‘NO VLAN’.
