4400 DTLS error AP will not register.

Question

I have just upgraded one of our 4400 to                  7.0.98.0.  Most of the AP re-registered with out issues. I have two AIR-LAP1142N-E-K9 on a remote site that will not re-register.
I have pointed them to another 2125 WLC (                  7.0.98.0) and they register fine. Point them to yet another 4400 (7.0.98.0) I get the same issue.
I am getting this error when the register on the 4400s.
*Jan 11 14:39:24.000: %CAPWAP-3-ERRORLOG: Selected MWAR 'abzewwlc'(index 1).

*Jan 11 07:06:55.000: %DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to 144.46.211.5:5246
I suspect it may be as they both have In the client config.Then again maybe not.
Configured Switch 1 Addr 158.139.177.203
Configured Switch 2 Addr 144.46.214.25
Question 1 if I do a "clear config except static IP" will I still be able to telnet tp them or will they default to no telnet no ssh ?
Question 2 any idea how to get past this DTLS error ?

Answer 1

Hi Stuart,
Please note that the AP is configured with wrong parameters for the 4402 WLC.
On the AP we have:
Primary Cisco Switch Name........................ lonwlc01
Primary Cisco Switch IP Address.................. 144.46.214.25
Secondary Cisco Switch Name...................... abzewwlc
Secondary Cisco Switch IP Address................ 144.46.211.4
But the 4402 WLC actually has:
System Name...................................... abzwwwlc
IP Address....................................... 144.46.211.6
Also, if you'd like the AP to join the 4402 as a first choice, you should configure it as follows:
Primary Cisco Switch Name........................ abzwwwlc
Primary Cisco Switch IP Address.................. 144.46.211.6
Secondary Cisco Switch Name...................... lonwlc01
Secondary Cisco Switch IP Address................ 144.46.214.25
Regards,
Fede
