controller to the DNS server. By default, DNS requests are sent every 15
minutes.

Usage Guidelines
If you define a RADIUS server using the FQDN of the server rather than its IP address, the controller will
periodically generate a DNS request and cache the IP address returned in the DNS response. Issue this
command to configure the frequency of these requests.

This command configures a DNS query interval of 30 minutes.
(host) # aaa dns-query-interval 30
