Filter Control
The wireless bridge can employ VLAN tagging support and network traffic frame
filtering to control access to network resources and increase security.
Native VLAN ID – The VLAN ID used to tag traffic passing from the wireless
interface to the wired network. (Range: 1-64)
VLAN – Enables or disables VLAN tagging support on the wireless bridge (changing
the VLAN status forces a system reboot). When VLAN support is enabled, the
wireless bridge tags traffic passing to the wired network with the assigned native
VLAN ID (a number between 1 and 64). Traffic received from the wired network
must also be tagged with the same VLAN ID. Received traffic that has an unknown
VLAN ID or no VLAN tag is dropped. When VLAN support is disabled, the wireless
bridge does not tag traffic passing to the wired network and ignores the VLAN tags
on any received frames.
Note: Before enabling VLANs on the
wireless bridge
, you must configure the connected
LAN switch port to accept tagged VLAN packets with the
wireless bridge
’s native
VLAN ID. Otherwise, connectivity to the wireless bridge will be lost when you
enable the VLAN feature.
Ethernet Type Filter – Controls checks on the Ethernet type of all incoming and
outgoing Ethernet packets against the protocol filtering table.
• Disable: Wireless bridge does not filter Ethernet protocol types.
• Enable: Wireless bridge filters Ethernet protocol types based on the configuration
of protocol types in the filter table. If a protocol has its status set to “ON,” the
protocol is filtered from the wireless bridge.
