Features
Bridge
Configuration
•
Bridge Mode
—Used to enable or disable Ethernet Bridging on the
radio. Default setting is
OFF
.
•
Basic Bridge Filter Sel
—Sets the type of bridge filter to be used.
Available selections are:
Broadcast/Unicast (All), Unicast and ARP,
and
Unicast Only
.
•
Adv Bridge Filter Status
—When on, this filter bridges the Ethernet
traffic received from a specific Ethernet-enabled device matching
one of the Adv Src Addr Filter Values (see below).
•
Adv Src Addr Filter Val
—Sets the Advanced SRC Address Filter
Values. Four address values are available. If the Adv Bridge Filter
Status is on, and an incoming Ethernet frame src addr matches
any of these values, the radio bridges the frame. Otherwise, it is
dropped by the radio. The entry format must be
xx:xx:xx:xx:xx:xx
.
VLAN Configuration
A VLAN is essentially a limited broadcast domain, meaning that all
members of a VLAN receive broadcast frames sent by members of the
same VLAN but not frames sent by members of a different VLAN.
The SD supports port-based VLAN at the Ethernet interface and over
the air, according to the IEEE 802.1Q standard. When VLAN Mode is
enabled, the wireless port of both AP and remote radios act as a trunk
port.
The Ethernet port of an AP radio is normally configured as a trunk port.
This type of port expects incoming frames to have a VLAN ID and sends
outgoing frames with a VLAN structure as well. The Ethernet port of a
Remote radio can be configured as an access port or as a trunk port.
When the Ethernet port of a Remote radio is configured as an Access
Port, the radio tags incoming traffic with a VLAN ID, and strips the tag
before sending out traffic. This traffic is known as the DATA VLAN.
Additionally, a
second
VLAN is assigned for other traffic that is termi-
nated at the radio, such as Web, Telnet, DLINK over TCP, TFTP repro-
gramming, etc. This traffic is known as the management VLAN. Traffic
directed to the terminal server or IP payload service should be sent via
the DATA VLAN.
