Operation and Administration
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 and Access Link (Access
Link option is available only in SUs).
The default selection is Hybrid Link.
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 5-7 summarizes the functionality of the data port for an Access link.

Trunk Link
Trunk Link transfers only tagged frames, since all devices connected to the
unit are VLAN-aware: Only tagged data frames received on the Ethernet or
wireless link ports are forwarded.
WARNING
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'.
