AP's keep looking for old DNS servers

Joswilder — Fri, 22 Jan 2021 23:29:51 GMT

We changed the dc’s so we pointed the AP’s to 1.1.1.1 and 1.0.0.1.

This works well. However, the AP’s keep looking for the old DNS servers.

In the firewall the deny rule is hit every 2 minutes from each AP.

I checked the entire ExtremeCloudIQ but the old servers are not listed anymore.

I also checked the config through the cli. The old DNS servers are not listed.

Hi there,

are your APs receiving their AP address by DHCP? Have you changed the DNS servers in your DHCP address pool, too?

Kind regards

Hi,

Yes, they receive there ip settings through DHCP.
The DNS servers are changed in the DHCP pool to 1.1.1.1 and 1.0.0.1
