I keep getting errors on different APs not joining controllers:

Jan  5 15:54:40.097: %CAPWAP-3-ERRORLOG: Go join a capwap controller
*Jan  5 15:54:40.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 10.x.x.x peer_port: 5246

*Jan  5 15:54:41.787: %DTLS-5-ALERT: Received WARNING : Close notify alert from 10.x.x.x
*Jan  5 15:54:41.788: %DTLS-5-PEER_DISCONNECT: Peer 10.x.x.x  has closed connection.
*Jan  5 15:54:41.788: %DTLS-5-SEND_ALERT: Send WARNING : Close notify Alert to 10.x.x.x :5246.

Any ideas?  I'm not sure why the peer is disconnecting the connection.  The controller that is linked to It happens on 1242 and 1231 APs mostly.  I've had it happen on a 1142 and 1252 once, but after a reboot it joined fine.

I'm running on 6 WISMs.  The ap-manager that these APs keep trying to join only has 5 APs on it.

Can you get a sniffer trace of the port-channel to one of the WiSM, and if possible, the console of the AP?  Also, check the MAC address of the AP(s) that are not joining to see if they start with something other than 00:, you may also want to check the MAC of the gw for those AP for the same thing.

The defect I'm thinking of is CSCte01087

I checked all the MAC's of the AP, GW, PO1-PO2, AP-Manager, Management, and Service-port and they all start with 00:  The APs are on a test VLAN

that starts 10.30.x.x and our WLC management VLAN is 10.200.x.x.  We are also running HSRP on the WLC and test VLANs.
