Instant AP and ClearPass DNS



I managed to setup instant AP, ClearPass and Clearpass guest talking  working thanks to a top video posted within the forum.


However I notice quite a delay when loading the caprive portal.It is my belief that this is due to the DNS timeout. I have seen this in few occasions with other vendor products in the past. The particular client I'm involved with  will not have a DNS server setup for the instant APs enviornment  as Instant APs will be working as a standlone offering.

For clients, I will be using  but I do not know  a workaround to  for the internal devices that require DNS service for IAP, CP and CP Guest components.


Update: 1 hour later :-)

When I tried authenticate against radiusit did not work.  I noticed that the radius is rejecting the user  stating" failed to clasify request to service"


Any advice/help is much appreciated.

Make sure that if the service has an Aruba-Essid-Attribute restriction, it matches your guest network.

Thanks for your reply.


Infact what you said was mentioned  on the video and I changed  it to match myworld.

Did a reboot asa last resort and things started working. May be as I was doing so many changes the AP/Clearpass would have gone bersek!!

However I'm still observing delays due to lack of DNS during redirection..

I'm thinking of using the ISP DNS to solve the challenge :-)
