CAS changed new DNS server IP but not using the new DNS servers
Last Updated May 17, 2019
You want to use a new DNS servers on the CAS. You have changed it on the Management Console and saved changes and you see the new IP has been saved but when you look at the traffic or Packet Capture, the DNS is still pointing towards the old IP address instead of the new ones.
A DNS interruption config change needs to happen usually to accept the new IP addresses. This can be done by following the steps below :
Remove DNS servers
Input new DNS servers
Alternatively a reboot on the CAS will take the new change as well.
