BreezeACCESS Version 4.3 System Manual
Bridge Parameters (AU, SU and GU)
The Bridge Parameters sub-menu includes the following parameters
sets:
 Virtual LAN (VLAN) parameters
 ToS parameters
 Ethernet Broadcast Filtering parameters
 Other Bridging parameters
 Ports Control Parameters
VLAN Parameters
 VLAN Support – Defines the parameters that are related to the
VLAN-aware (Virtual LAN-aware) feature of BreezeACCESS units.
Each VLAN includes stations that can communicate with each
other, but cannot communicate with stations belonging to different
VLANs. The VLAN also provides the ability to set traffic priorities for
transmission of certain frames. The information related to the VLAN
is included in the VLAN Tag Header, which is inserted in each frame
between the MAC header and the data. VLAN implementation in
BreezeACCESS units supports frames routing by port information
(i.e. each port is connected to only one VLAN).
The VLAN Support option allows viewing and setting of the
following parameters:
 VLAN ID-Data (SU unit only) – Applicable for Access links only.
Sets the VLAN ID for data frames, identifying the VLAN to which
the unit belongs.
 Valid values: 1 to 4094.
 Default value: 1.
 Frames received from the Wireless link port:
 Only tagged frames with VLAN ID (VID) value equal to
the VLAN ID Data defined in the unit are forwarded to
the Ethernet port.
 The tag headers are removed from the data frames
received from the wireless link prior to transmitting them
on the Ethernet port.
Frames received from the Ethernet port:
 A VLAN data tag is inserted in all untagged frames
received from the Ethernet port before transmission on
the wireless link. The tag includes the values of the VLAN
ID – Data and the VLAN Priority – Data parameters.
 Tagged frames received on Ethernet port which are
designed to be forwarded to the Wireless link port are
discarded (including frames with priority tag for
prioritization purpose only).
