Error Message in cisco controller

Hello All,

When setting DCA interval to 8 hours, it shows the below error. 

"DCA channel interval cannot be set"

Any guess. Thanks in advance

If you are running v8.2MR1, there is a new feature called Flexible Radio Assignment.  You might be running into this as it is set to 1 hour.  You need to set the FRA to an equal of higher value:

config advanced fra interval 24

config advanced 802.11a channel dca interval 24

save config

y

Hope this helps

Did you disable your radios (2.4 & 5 GHz) on your WLC  first ? If not try that

Still applicable to 8.2.141.0

How stupid that is? My FRA is disable, but I still have to go into CLI to set it to 24H, without it GUI doesn't allow to change DCA. Cisco is soooo Cisco.

We have an enhancement request (CSCva05977) submitted to resolve this issue in 8.3 and 8.4 releases. As of today it looks like neither has received a commitment to the versions. Please encourage your Cisco contacts to push for these resolutions.

Thanks Chris
