The dns proxy forward-any-response command configures the DNS proxy to forward all the response packets returned by the DNS server to DNS clients. The response packets include those with the response count being 0, those with error codes, and those that are resolved successfully.
The undo dns proxy forward-any-response command configures the DNS proxy to forward only the successfully resolved response packets returned by the DNS server to DNS clients.
By default, the DNS proxy forwards only the successfully resolved response packets returned by the DNS server to DNS clients.

This command is supported in V600R007C20SPC500 and later versions.
When a DNS client sends a DNS request packet to detect whether a DNS server is available on the network, the DNS client considers that a DNS server is available if it receives a response packet from the DNS server, regardless of whether the response packet is successfully resolved. To enable the DNS proxy to forward all the response packets returned by the DNS server to the DNS client, run the dns proxy forward-any-response command.
