Command Usage
The ip address dhcp command allows any interface to dynamically learn its IP address by using
the DHCP protocol.
Some DHCP servers require that the DHCPDISCOVER message have a specific host name. The
ip address dhcp hostname host-name command is most typically used when the host name is
provided by the system administrator.
If the device is configured to obtain its IP address from a DHCP server, it sends a
DHCPDISCOVER message to provide information about itself to the DHCP server on the
network.
If the ip address dhcp command is used with or without the optional keyword, the DHCP option
12 field (host name option) is included in the DHCPDISCOVER message. By default, the
specified DHCP host name is the globally configured host name of the device. However, the ip
address dhcp hostname host-name command can be used to place a different host name in the
DHCP option 12 field.
The no ip address dhcp command de-configures any IP address that was acquired, thus sending
a DHCPRELEASE message.
Example
The following command acquires an IP address for Ethernet port 1/e16 from DHCP.
Console(config)# interface ethernet 1/e16
Console(config-if)# ip address dhcp
11-2
