226 Configuring AP access points
320657-A
or
host:hostname1,hostname2,...
You can use an IP address list or a hostname list, but not both. If the list contains both types of values, the AP does not
attempt to use the list.
The ip and host keywords can be in lowercase, uppercase (IP or HOST), or mixed case (example: Ip, Host, and so on.)
You can use spaces after the colon or commas, but spaces are not supported within IP addresses or hostnames. Leading
zeroes are supported in IP addresses. For example, 100.130.001.1 is valid.
Valid characters in hostnames are uppercase and lowercase letters, numbers, periods ( . ), and hyphens ( - ). Other char-
acters are not supported.
If you use the host option, you must configure the network’s DNS server with address records that map the hostnames in
the list to the WSS IP addresses.
After receiving a DHCP Ack containing a valid string for option 43, a Distributed AP sends a unicast message to the
each WSS switch in the list, to request a software image and configuration. If the AP does not receive a reply to the
request after one minute, the AP starts the boot process over with a new DHCP Discover message, this time from AP
port 2.
No configuration is required on the WSS itself.
AP Parameters
Table 7 on page 226 summarizes parameters that apply to individual AP access ports, including dual-homing parame-
ters. (For information about parameters for individual radios, see “Configuring a Radio Profile” on page 267 and
“Configuring Radio-Specific Parameters” on page 273.)

Parameter Default Value Description
name Based on the port or

connection number.
For example:
•AP01
•DAP01
AP name.
bias high Setting an AP’s bias on a WSS to high
causes the switch to be preferred over
switches with low bias, for booting and
managing the AP.
Note: Bias applies only to WSSs that are
indirectly attached to the AP through an
intermediate Layer 2 or Layer 3 network. An
AP always attempts to boot on AP port 1
first, and if a WSS is directly attached on
AP port 1, the AP boots from it regardless of
the bias settings.
