DHCP Commands
These commands are used to configure Dynamic Host Configuration Protocol (DHCP) client and
relay functions. Any VLAN interface can be configured to automatically obtain an IP address
through DHCP. This switch can be configured to relay DHCP client configuration requests to a DHCP
server on another network.

address information.
