ISE ver 1.1.3.124 - DNS Resolution Errors.

ASPasha · ‎04-15-2013

I am having a very strange issue with ISE version 1.1.3.124 running as a VM on UCS.

When I login to ISE GUI using my browser I see a large number of Alarms:

Alarm

Occurred At:

Mon Apr 15 19:45:01 UTC 2013

Cause:

DNS resolution failure on host device_name01.abc.xyz.com

Details:

DNS resolution failed for the hostname device_name01.abc.xyz.com
against the currently configured name servers. Ensure that you have configured a reachable name server using the 'ip name-server <servername>' CLI.

I have the 'ip name-server x.y.z.1' command configured in ISE using the CLI.

From the CLI I resolve any other device names by PINGing from ISE CLI to any of my other devices in the network. So DNS seems to be working fine.

But why am I getting the Alarms in ISE?

Thanks for any help or suggestion in advance.

Regards.

Adil.

Can you confirm that you have an A record for the ISE node configured on your DNS Server?

If there is only a CNAME record, then you may see the specified error message.

Hi Adil,

Did you find a solution to your problem? I am seeing the same error for one of my four ISE-servers.
