Ip Address Dhcp - Dell PowerConnect 6024F Command Line Interface Reference Manual

ip address dhcp

The ip address dhcp interface configuration command acquires an IP address on an interface from
the Dynamic Host Configuration Protocol (DHCP) server. To deconfigure any acquired address,
use the no form of this command.
The no ip address dhcp command deconfigures any IP address that was acquired, thus sending a
DHCPRELEASE message.
Syntax
ip address dhcp [hostname host-name]
no ip address dhcp
• host-name—Specifies the DHCP host name. This name need not be the same as the host
name entered in global configuration mode. (Range: 1-159 characters)
Default Configuration
This command has no default configuration.
Command Mode
Interface configuration (Ethernet, VLAN, port-channel, out-of-band Ethernet)
User Guidelines
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 most typical usage of the ip address dhcp hostname host-name command is when host-
name is the host name provided by the system administrator.
If a router 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 device globally configured host name.
The ip address dhcp command is not supported on a range of interfaces.
The inband ports of the device are router ports. Therefore, when an interface is defined on
the inband ports (or VLAN of which they are members), no default-gateway is configured.
After dynamic assignment of the IP interface, manually assign a default route.
