232 Configuring AP access points
320657-A
● IP address for the AP
● Domain name of the network
● IP address of the network’s DNS server
● IP address of the subnet’s default gateway
Optionally, the Offer message can also contain a list of WSS IP addresses or hostnames, in the
option 43 field of the DHCP message.
Continuing the DHCP process, the AP broadcasts a DHCP Request to the DHCP servers, and
receives an Ack from a DHCP server. The AP then configures its network connection with the
information contained in the Ack message from that server.
3 The AP sends a Find WSS message to UDP port 5000 on the subnet broadcast address.
● WSS switches in the same IP subnet as the AP receive the message and respond with a
Find WSS Reply message.
❍ If the AP is configured as a Distributed AP on a switch and the
connection bias is high, the WSS switch immediately sends a Find
WSS Reply message.
❍ If the AP is configured as a Distributed AP on a switch but the
connection bias is low, that WSS switch waits one second, then sends
a Find WSS Reply message. The delay allows switches with high bias
for the AP to respond first.
❍ If an WSS switch that receives the Find WSS message does not have
the Distributed AP in its configuration but another WSS switch in the
same Mobility Domain does, the switch waits two seconds, then
sends a Find WSS Reply message with the IP address of the best
switch to use. The determination of best switch is based on the bias
settings for the AP on each switch and on the capacity of each switch
to add new active AP connections.
The process skips to step 10.
● If no WSS switches reply, the AP resends the Find WSS broadcast up to 11 more times. If
no WSSs reply after all 12 attempts, the AP attempts to find an WSS based on DHCP
option 43 values received in the DHCP Ack. The process continues with step 4.
4 This step applies only if the DHCP Ack contained WSS IP addresses or hostnames in the option
43 field. If the Ack did not contain WSS IP addresses or hostnames in the option 43 field, skip
to step 5.
If the DHCP Ack message contained a list of WSS IP addresses or hostnames in the DHCP
option 43 field, the AP contacts the WSS switches:
● If the DHCP Ack message contained a list of WSS IP addresses, in DHCP option 43, the
AP sends a unicast Find WSS message to each address. The process continues with step 8.
