Domain Name System
The switch supports IPv4 DNS client functionality. When enabled as a DNS client,
the switch provides a hostname lookup service to other applications on the switch
such as ping, RADIUS, syslog, Auto Configuration, and TFTP. The switch can be
configured with DNS servers that resolve hostnames to IP addresses. The switch
can also be configured with static host-name-to-IP-address mappings that bypass
the DNS server.
