Primary Port Settings
Two options allow you to designate the access point’s 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 the 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.
