Default Unicast Address Filter
Unicast MAC address filters allow or disallow the forwarding of unicast 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 “Setting Up MAC-Based Authentication” section on page 4-28 for
complete instructions on using MAC-based authentication on an authentication
server. Read the “Creating a MAC Address Filter” section on page 3-14 for
complete instructions on setting up MAC address filters.
The pull-down menus for unicast 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 or on your
authentication server.
Select Disallowed for each authentication type that also uses MAC-based
authentication.
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 or on your authentication server to avoid being locked out of
the access point.
Specified Access Points
You use these fields to set up a chain of repeater access points (access points
without an Ethernet connection; see Figure 3-3). Repeater access points function
best when they associate with specific access points connected to the wired LAN.
You use these fields to specify the access points that provide the most efficient
data transmission link for the repeater.
If this access point is a repeater, type the MAC address of one or more root-unit
access points with which you want this access point to associate. With MAC
addresses in these fields, the repeater access point always tries to associate with
the specified access points instead of with other less-efficient access points.
