Example boot of AP with static IP configuration
Figure 17 shows an example of the boot process for an AP configured with static IP information. In the example, the AP
has been configured to use the following:
• Static IP address: 172.16.0.42, netmask: 255.255.255.0, default router 172.16.0.20
• Boot WSS: 2350, DNS server: 172.16.0.1
Figure 17. AP booting with a static IP address
After the AP is configured with the above information, the next time the AP boots, the following takes place
1 The AP sends an ARP request for its own address, to ensure it is not in use elsewhere in the network.
2 The DNS server resolves the fully qualified domain name of the WSS, 2350.
3 The AP sends a Find WSS message to the WSS 2350.
4 The WSS 2350 responds to the Find WSS message
5 The AP sends a unicast message to WSS 2350 and determines whether it should use a locally stored
operational image or download it from the WSS.
6 Once the operational image is loaded, WSS 2350 sends configuration information to the AP.
Session load balancing
You can assign APs to a load-balancing group. A load-balancing group helps reduce congestion by distributing client
sessions among the APs in the group. For example, if an 802.11b/g radio operating on channel 1 is supporting more
