III. Configuration procedure
Note:
First suppose the switch and host 1 are reachable to each other, the DNS server works
normally, and a mapping entry from host to IP address 3.1.1.1/16 exists on the DNS
server.
# Enable dynamic DNS resolution.
<H3C> system-view
[H3C] dns resolve
# Configure the DNS server IP address 2.1.1.2.
[H3C] dns server 2.1.1.2
# Configure net as a DNS suffix.
[H3C] dns domain net
# Configure com as a DNS suffix.
Figure 1-2, a switch is used as a DNS client with dynamic DNS resolution.
