• Management frames generated by the unit will not be
tagged.
•If the Voice Priority Tag Option is enabled, a VLAN
Priority Tag is inserted in all voice frames (RTP packets)
generated by the unit before transmission to the Wireless
or Ethernet port. The tag includes a VID value of zero
and the VLAN Priority – Voice parameter.
The following table summarizes the functionality of the
internal management and voice ports in accordance with the
value of the VLAN ID – Voice & Management parameter.
The table is valid for all link types. See VLAN Link type –
Access Link and Trunk Link for some restrictions when
configuring this parameter.

 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.
