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 DISCOVER
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 deconfigures any IP address that was
acquired, thus sending a DHCPRELEASE message.
Example
The following example acquires an IP address for Ethernet port 1/e16 from DHCP.
Console(config)# interface ethernet 1/e16
Console(config-if)# ip address dhcp
