Hostname Mapping

hostnames and IP addresses. You can statically associate a hostname with an IP
address. You can also view hostnames that have been learned dynamically
through applications that use the DNS lookup service.
NOTE If you configure a static hostname and IP address, and that same hostname IP
address mapping is later learned from DNS, the entry becomes dynamic and it is
no longer saved as a static entry in the the Running Configuration.

addresses on the switch. To configure a static hostname mapping:
STEP 1 Click IP Configuration > Domain Name System > Host Mapping in the navigation

STEP 2 Click Add.
STEP 3 Enter a hostname from 1–255 alphanumeric characters. The hostname must begin
with a letter.
STEP 4 Enter an IPv4 or IPv6 address to be associated with the hostname.
