Hi all,

I have deployed virtual 9800 WLC (version 16.12.01t) and joined 3800 series AP with it. But AP is unable tethering the SSID created and shown Operation status as down. Please refer the  screenshot.

Please help me out with this issue,

Hi John,

Hi Vamsi - 

During the install,  did you select the country code for the AP the default would have been US?

Hi John,

Thanks for the response.

Issue solved after replacing the switch 3560 to 3850, since PoE to AP from Interface Fast ethernet was not sufficient to enable Radio Frequency. But still AP is not tethering the SSIDs. Please help me out.

Hi Vamsi - 

I hope I understand your question.  so after swapping the switch your AP is now saying it is operationally up and you are not seeing a preconfigured SSID is this correct?

If so they way the 9800 works with wireless network has changed.  Based on the modular design we use profiles and tags.  you create a policy profile and a WLAN Profile  which the WLAN profile creates your SSID settings and the Policy profile creates your L2 network.  We then link them together in a Policy Tag. 

If creating a unique policy tag can you check that this is selected on the general tab of you access point and is not assigned to the default-policy-tag.

Here is a link that may help you.
