How to Shutdown the DNS Proxy Server

Describes how to shutdown the DNS Proxy server.

Context

The DNS Proxy server shuts down with the DHCP server. If an IAP is configured to shutdown the DHCP server, it shuts down the DHCP server which in turn shuts down the DNS Proxy server. DNS Proxy server frees all its resources and deletes all the host name entries present in the DNS local database before shutdown. DNS Proxy server stops receiving DNS requests on the interface when it is shutting down.

Note: DNS Proxy server supports handling of multiple requests coming from a single interface and does not support receiving DNS requests on multiple interfaces.
