 PID-M: VLAN Priority-Management
4.2.6.4.1.3 VLAN Link Type
The VLAN Link Type parameter enables defining the functionality of the VLAN
aware capability of the unit.
The available options are Hybrid Link, Trunk Link, Access Link and Service
Provider Link (Access Link option is available only in SUs).
The default selection is Hybrid Link.
4.2.6.4.1.3.1 Access Link (SU only)
Access Link transfers frames while tagging/untagging them since all devices
connected to the unit are VLAN unaware. Thus, the unit cannot transfer tagged
frames.
Table 4-8 summarizes the functionality of the data port for an Access link.

4.2.6.4.1.3.2 Trunk Link
Trunk Link transfers only tagged frames, as all devices connected to the unit are
VLAN aware. Only tagged data frames received on the Ethernet or wireless link
ports are forwarded.

Tag Insert VID-D, PID-D (to wireless)
Tag Remove Yes (to Ethernet)
CAUTION
It is not recommended that you configure a unit as a Trunk Link with the VLAN ID-Management
parameter set at 65535, as it does not forward any 'NO VLAN' management frames to its other port,
making it impossible to manage devices connected behind the unit that are also configured with 'NO
VLAN'.
