Chapter 3 Radio Configuration and Basic Settings

Radio Configuration

Primary Port Settings

Two options allow you to designate the radio port as the Primary Port and select whether the radio port adopts or assumes the identity of the primary port.

•Primary Port?—The primary port determines the access point’s MAC and IP addresses. Ordinarily, the access point’s primary port is the Ethernet port, which is connected to the wired LAN, so this setting is usually set to no. Select no to set the Ethernet port as the primary port. Select yes to set the radio port as the primary port.

•Adopt Primary Port Identity?—Select yes to adopt the primary port settings (MAC and IP addresses) for the radio port. Select no to use different MAC and IP addresses for the radio port.

Access points acting as root units adopt the primary port settings for the radio port. When you put an access point in standby mode, however, you select no for this setting. Some advanced wireless bridge configurations also require different identity settings for the radio port.

Default IP Address

Use this setting to assign an IP address for the radio port that is different from the access point’s Ethernet IP address. During normal operation the radio port adopts the identity of the Ethernet port. When you put an access point in standby mode, however, you assign a different IP address to the radio port. Some advanced wireless bridge configurations also require a different IP address for the radio port.

Default IP Subnet Mask

Enter an IP subnet mask to identify the subnetwork so that the IP address can be recognized on the LAN. If DHCP or BOOTP is not enabled, this field is the subnet mask. If DHCP or BOOTP is enabled, this field provides the subnet mask only if no server responds to the access point’s request.

The current IP subnet mask displayed under the setting shows the IP subnet mask currently assigned to the access point. This is the same subnet mask as the default subnet mask unless DHCP or BOOTP is enabled. If DHCP or BOOTP is enabled, this is the subnet mask used by the DHCP or BOOTP server.

You can also enter this setting on the Express Setup page.

Service Set ID (SSID)

An SSID is a unique identifier that client devices use to associate with the access point or a VLAN supported by the access point. The SSID helps client devices distinguish between multiple wireless networks and VLANs in the same vicinity and provides access to VLANs by wireless client devices. Several access points on a network or subnetwork can share an SSID. You can configure up to 16 SSIDs per radio on an access point. An SSID can be any alphanumeric, case-sensitive entry from 2 to 32 characters long.

Click more to go to the AP Radio Service Sets page where you can create additional SSIDs. From this page you can also edit an existing SSID or remove one from the system.

You can also enter this setting on the Express Setup page.

LEAP User Name

Use this field if the radio is set up as a repeater and authenticates to the network using LEAP. When the radio authenticates using LEAP, the access point sends this user name to the authentication server.

Follow the steps in the “Setting Up a Repeater Access Point” section on page 12-2to set up the radio as a LEAP client.
