Configuring APs 231Nortel WLAN—Security Switch 2300 Series Configuration Guideprofile with a high bias setting. If more than one WSS has an Auto-AP profile with a high bias setting, the switch that hasthe greatest capacity to add new unconfigured APs is selected.A WSS’s capacity to add new unconfigured Distributed AP’s is the lesser of the following:• Maximum number of APs that can be configured on the switch, minus the number that are configured• Maximum number of APs that can be active on the switch, minus the number that are activeFor example, suppose the Mobility Domain has two WSSs, with the capacities and loads listed in Table 6.For 2360/2361 A:• The Number of APs that can be configured on the switch, minus the number that are configured, is 30 - 25 = 5.• The Number of APs that can be active on the switch, minus the number that are active, is 12 - 8 = 4.• The lesser of the two values is 4. The switch can have up to 4 more APs.For 2360/2361 B:• The Number of APs that can be configured on the switch, minus the number that are configured, is 30 - 20 = 10.• The Number of APs that can be active on the switch, minus the number that are active, is 12 - 12 = 0.• The lesser of the two values is 0. The switch can have no more APs.2360/2361 A has the capacity to add 4 more APs, whereas 2360/2361 B cannot add any more APs. Therefore, the WSScontacted by the AP sends 2360/2361 A’s IP address to the AP. The AP then requests a software image file and configu-ration from 2360/2361 A. 2360/2361 A sends the software image and sends configuration parameters based on theAuto-AP profile.Configured APs have precedence over unconfigured APsWhen a WSS determines the WSS IP address to send to a booting AP, the switch gives preference to APs that arealready configured, over unconfigured APs that require an Auto-AP profile. The WSS can direct a configured AP to aswitch that has active APs configured using the Auto-AP profile, even if the switch does not have capacity for moreactive APs. In this case, the WSS randomly selects an AP using the Auto-AP profile to disconnect, and accepts a connec-tion from the configured AP in its place.The disconnected AP can then begin the boot process again to find another WSS that has an Auto-AP profile. When theAP is disconnected, the AP’s clients experience a service disruption, and will attempt to associate with another AP ifavailable to reconnect to the SSID they were using. If another AP is not available to a client, the client can still reconnectafter the disconnected AP is connected to a new WSS and finishes the boot and configuration process.Table 6: Example 2360/2361 AP capacities and loads2360/2361 A 2360/2361 BMaximum Configured 30 30Maximum Active 12 12Number Currently Configured 25 20Number Currently Active 8 12
