I have 2 WLAN SSID, one's working the other isn't! Recently one of our Controllers rebooted, and then one of of WLAN's stopped working. I've checked the configs and code and they are the same on both controllers. The WLAN that is not working I see the following log message:
Mar 19 09:40:31.464 apf_foreignap.c:1281 APF-4-REGISTER_IPADD_ON_MSCB_FAILED: Could not Register IP Add on MSCB. MSCB still in init state. Address:00:40:96:a7:50:c6
My laptop is connected and has authenticated to the WLAN but gets a default windows IP 169.254.36.162 same result with my IPhone. I know its not my laptops driver as the other WLAN on the same controller works fine. For some reason the client ARP cannot be added to the controller for this WLAN SSID. I found the following from Cisco, but just wondering if anyone has any other suggestions (fyi - controller software 4.2.207.0)
A. This is the error message:
APF−1−REGISTER_IPADD_ON_MSCB_FAILED: Could not RegisterIP Add on MSCB. MSCB still in init state.
The Mobile Station Control Block (MSCB) represents the clients. This error message means that a client tries to pass traffic, but the controller is not yet ready to accept the client traffic. These messages are generated when the controller gets an ARP request from a client but it has not added the IP address of the client to its client list. Once the controller adds the client IPaddress to its client list, everything should be fine. As a workaround, try to reboot the controller to see if it helps. Also, make sure you run the latest drivers for the wireless cards of the client because there have been several connectivity issues with older card drivers specifically with some third party wireless cards.
