Dynamic Host Name Mapping
Use the Dynamic Host Name Mapping page to view dynamic host entries
the switch has learned. The switch learns hosts dynamically by using the
configured DNS server to resolve a hostname. For example, if you ping
www.dell.com from the CLI, the switch uses the DNS server to lookup the IP
address of dell.com and adds the entry to the Dynamic Host Name Mapping
table.
To display the Dynamic Host Name Mapping page, click System → IP
Addressing → Dynamic Host Name Mapping in the navigation panel.
