2nd DNS does not stay

    I noticed that the 2nd DNS server on the internal DHCP server does not stay. I have added it several times and saved the configuration. I click on something else then go back to the internal DHCP server and the 2nd DNS server is gone. I made sure there was a space in between the servers when configuring. Running Aruba OS 5.0.3.3.

    Type "show audit-trail" to see what was configured.

    When I run "show audit-trail" it just shows login info.

    When I do a "show run" and go to where the IP pool is it only see one of the DNS servers.

    did you confirm the pressing both apply buttons I mention in the above post?   if so, did you try the CLI command rather than WebUI?

    As mentioned earlier by clembo, please hit apply on both pages

     

    Network > IP > DHCP > Edit DHCP Pool (guest) -> Add Multiple DNS entries -> Apply 

     

    As soon as you hit Apply, it will take you back to following page where you have to hit Apply again.

    Network > IP > DHCP Server -> Apply

     

    Make sure you see a message saying "Configuration Updated Successfully"

    It would only save when going to CLI worked. Thanks.

    Make sure that you hit Apply on both the page where you defined the second DNS server, but then also again on the next page that shows the the pools and exclusions/etc.  That second apply  is often missed.


    If you continue to have problems; put it in through the CLI:

     

    ip dhcp pool "PoolNamel" dns-server 8.8.8.8 4.2.2.2
