AP is unable to associate. The Regulatory Domain '-E' configured on interface '802.11a' does not match the Controller Regulatory Domain '-C'

[Syed Yasir Imam]

Hi,

There are three different types of APs associated with controller and working fine.

1.       AIR-LAP1252AG-E-K9

2.       AIR-LAP1522AG-E-K9

3.       AIR-CAP1552E-C-K9

WLC is AIR-CT5508-K9. Software version is 7.4.100.0. Field Recovery Image is 7.0.112.21. Firmware version is FPGA 1.7, Env 1.8, USB console 2.2. WCS is 7.0.240.0 for Windows.

WCS is sending alarms for AIR-LAP1522AG-E-K9:

Message: AP is unable to associate. The Regulatory Domain '-E' configured on interface '802.11a' does not match the Controller Regulatory Domain '-C'.

Before Controller was 7.2.4 (not sure).

Country configured on WLC is AE and shows -CE regulatory domain. Mesh APs are also associated.

I believe this Critical alarm should not come.

how much is this alarm important? What should be done to resolve this?

Typically you still need to make sure that the country codes are indeed configured on the WLC. Thing can change when you upgrade code as standards might of changed and regulations also. If your AP's are functional, then you should be okay and I wouldn't worry too much about it, but if after the upgrade, the WLC complains about country code stuff, then you just need to verify that the AP's country code is defined on the WLC. May times the AP will not join and if it does join, the radios might be disabled or in a down status.
