Radio Configuration
Default Multicast Address Filters
MAC address filters allow or disallow the forwarding of multicast packets sent to specific MAC
addresses. You can create a filter that passes traffic to all MAC addresses except those you specify, or
you can create a filter that blocks traffic to all MAC addresses except those you specify. Read the
“Creating a MAC Address Filter” section on page 5-7 for complete instructions on setting up MAC
address filters.
The pull-down menus for multicast address filters contain two options:
• Allowed—The access point forwards all traffic except packets sent to the MAC addresses listed as
disallowed on the Address Filters page.
• Disallowed—The access point discards all traffic except packets sent to the MAC addresses listed
as allowed on the Address Filters page.
Note If you plan to discard traffic to all MAC addresses except those you specify (the Disallowed setting), be
sure to enter your own MAC address as allowed on the Address Filters page to prevent being locked out
of the access point.
Maximum Multicast Packets/Second
Use this setting to control the number of multicast packets that can pass through the radio port each
second. If you enter 0, the access point passes an unlimited number of multicast packets. If you enter a
number other than 0, the device passes only that number of multicast packets per second.
Radio Cell Role
Use this pull-down menu to select the function of the radio within its radio coverage area (cell). This
setting determines how the radio interacts with other wireless devices. The menu contains the following
options:
• Root—A wireless LAN transceiver that connects an Ethernet network with wireless client stations
or with another Ethernet network. Use this setting if the access point is connected to the wired LAN.
• Repeater/Non-Root—A wireless LAN transceiver that transfers data between a client and another
access point. Use this setting for access points not connected to the wired LAN.
• Client/Non-root—A station with a wireless connection to an access point. Use this setting for
diagnostics or site surveys, such as when you need to test the radio by having it communicate with
another access point or bridge without accepting associations from client devices.
SSID For Use By Infrastructure Stations
Use this entry field to identify the SSID to be used by repeaters and workgroup bridges to associate to
the access point. This SSID should be mapped to the native VLAN ID in order to facilitate
communications between infrastructure devices and a non-root access point or bridge.
Disallow Infrastructure Stations on Any Other SSID
Use this setting to prevent repeaters and workgroup bridges from associating to SSIDs other than the
infrastructure SSID. The default setting is No, so to invoke this condition, you must change the setting
to Yes.
