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 4-7 summarizes the func
tionality of the data port for an Access link.

Trunk Link
Trunk Link transfers only tagged fram
VLAN aware. Only tagged data frames received on the Ethernet or wireless l
ports are forward
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'.
If the VLAN Forwarding option is enabled, a data frame received with a VLAN ID
that is not a member of the unit's VLAN Forwarding List is discarded.
NOTE
If the VLAN Forwarding option is enabled, be sure to include the VLAN ID-Management value of
all units that should be managed via the wireless port of the unit, in the Forwarding List.
If the VLAN Relaying option is enabled in an AU, a data frame relayed with a
VLAN ID that is not a member of the unit's VLAN Relaying List is discarded.
