(problem resolved)
Hello
When I setup the AP 's intelligent smart upgrade. It request me to set DNS server.
When I create DNS server. Whatever I type (eg:8.8.8.8), gateway IP or itself IP. always get error Error: Please Configure the source address used to connect to the DNS server. It should be what address?
Thanks

I checked the DNS configuration method and found that the source address needs to be configured only when the DNS proxy is configured. If the DNS static resolution is configured, the source address does not need to be configured. Can you try to configure it on the command line? Run the dns server source-ip x.x.x.x command to configure the source address.

alright, The source address must be an existing address on the device. The source address cannot be 8.8.8.8. If the error message indicates that the IP address already exists, can the DNS server be configured directly?

dns server source-ip 10.0.0.12(ap address) -> "Error: The source IPv4 address already exists." dns server source-ip 8.8.8.8 -> no error. But there is empty in "disp dns server"

That's not true, you can try to configure the commands I'm telling you. dns server 8.8.8.8 If prompted to configure the source address, add a command. dns server source-ip x.x.x.x Run the following command to check whether the DNS configuration exists on the device: display cu | in dns |
