Hi 

 

I am new to Wireless network and have been tasked with setting v WLC Cisco and AIR-CAP702I-I-K9. I followed some guides to configure the WLC, but however the APs are not joining the controller. with console cable connected to the AP i get the following;

The vWLC is running the wrong or outdated firmware.  For a AP702, the vWLC should be running a minimum of 7.6.X formware. 

 

I would, however, recommend you run the latest 7.6.130.X as this is a stable version and 7.5.X is classified as "deferred".

That's right!!

I am getting the same error ,as you can see my time is correct , I can ping the AP from WLC

any idea ? much appreciated

There is certification verification failed & hence AP not registered. 

Check in your vWLC to see correct time "show time" output verify this.

Hi

As we can see WLC does not have correct time

Sync WLC to a NTP server to get the correct time. Then AP should register

Hi 

 

Can you suggest an NTP server on windows 7

 

thanks

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

You can use public NTP server that can found here

http://www.pool.ntp.org/en/

If you have a router as internet gateway, sync that device to one of this public NTP server & then all your internal device to sync with your router as NTP.

See this post for basics of NTP functionality

Hi 

 

So if I correctly understand , the problem is the result of the missing of the synchronization between AP and vWLC although I have set the time on the vWLC and I verified that the PA has the same time.
Is it mandatory to have an NTP server? 

 

Best regards 

Is it mandatory to have an NTP server?

It is mandatory to have the correct time & sync to NTP is the best way to do it. You can manually set the time, but accuracy will be not that high.  Also when you have RADIUS servers/ AD /MSE/ Prime integrated, every thing should sync to a common NTP to get them work, manual clock setting is not practical in those scenarios.

Try to set WLC time manually & see your APs get registered.

Hi

 

USUALLY if I manually adjusts the time, the cli AP it will not display the error
but every time I manually adjusts the time it shows the same error

Time............................................. Fri Dec 12 15:50:48 2014

I agree with Rasika.  

 

The AP won't join the controller because the WLC's time & date are incorrect. 

Can you suggest an NTP server on windows 7

Windows OS do NOT adhere to NTP/SNTP standard.  Windows OS will work well as an NTP client but never as an NTP server.  

 

The best method to get NTP is to use public NTP pool found on the internet.
