Controller software enables you to configure the access points to send all
The state of the access point is not maintained on the controller until it receives a CAPWAP join request from the access point. Therefore, it can be difficult to determine why the CAPWAP discovery request from a certain access point was rejected. In order to troubleshoot such joining problems without enabling CAPWAP debug commands on the controller, the controller collects information for all access points that send a discovery message to it and maintains information for any access points that have successfully joined it.
The controller collects all
You can view
•Up to 300 access points for 4400 series controllers, the Cisco WiSM, and the Catalyst 3750G Integrated Wireless LAN Controller Switch
•Up to three times the maximum number of access points supported by the platform for the 2600 series controllers and the Controller Network Module within the Cisco 28/37/38xx Series Integrated Services Routers
When the controller is maintaining
An access point sends all syslog messages to IP address 255.255.255.255 by default when any of the following conditions are met:
•An access point running software release 5.2 or later has been newly deployed.
•An existing access point running software release 5.2 or later has been reset after clearing the configuration.
If any of these conditions are met and the access point has not yet joined a controller, you can also configure a DHCP server to return a syslog server IP address to the access point using option 7 on the server. The access point then starts sending all syslog messages to this IP address.
When the access point joins a controller for the first time, the controller sends the global syslog server IP address (the default is 255.255.255.255) to the access point. After that, the access point sends all syslog messages to this IP address until it is overridden by one of the following scenarios:
•The access point is still connected to the same controller, and the global syslog server IP address configuration on the controller has been changed using the config ap syslog host global syslog_server_IP_address command. In this case, the controller sends the new global syslog server IP address to the access point.
