Domain Name System (DNS) Client

The Domain Name Service (DNS) translates domain and host names to and from IP addresses. A DNS client resolves hostnames to IP addresses by querying assigned DNS servers for the appropriate IP address.

Configuration commands

(switch#) Configure the switch to resolve queries via a DNS server:

ip dns server-address IP-ADDR [vrf VRF]

(switch#) Configure a domain name:

ip dns domain-name NAME

Show commands to validate functionality

(switch#)

show ip dns

Expected results

  • Administrators can configure the DNS client.
  • The output of all commands is correct.
  • Administrators can ping the device.
