Bridge Parameters
The Bridge Parameters menu provides a series of parameter sets that
enables configuring parameters such as control and filtering options for
broadcast transmissions, VLAN support, and Type of Service
prioritization.
VLAN Support
The VLAN Support menu enables defining the parameters related to the
IEEE 802.1Q compliant VLAN aware (Virtual LAN aware) feature of the
BreezeNET B units. Each VLAN includes stations that can communicate
with each other, but cannot communicate with stations belonging to
different VLANs. The VLAN feature 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
BreezeNET B units supports frame routing by port information, whereby
each port is connected to only one VLAN.
The VLAN Support menu enables configuring the following parameters:
VLAN ID-Data (RB only)
The VLAN ID-Data is applicable for Access Links only. It enables
defining the VLAN ID for data frames, which identifies the VLAN to
which the unit belongs.
Valid values range from 1 to 4094.
Default value: 1.
The VLAN ID-Data affects frames received from the wireless link port, as
follows:
 Only tagged frames with a VLAN ID (VID) 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 before they are transmitted on the Ethernet port.
The VLAN ID-Data affects frames received from the Ethernet port, as
follows:
 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.
