ip address dhcp
Use the ip address dhcp command to use Dynamic Host Configuration Protocol (DHCP) to obtain an
address on the Ethernet interface. Use the no form of this command to remove a configured IP address
(using DHCP) and disable DHCP operation on the interface.
ip address dhcp {client-id [<interface> | <identifier>] hostname “<string>” }
Syntax Description
client-id Optional. Specifies the client identifier used when obtaining an IP address from a
DHCP server.
<interface> Specifying an interface defines the client identifier as the hexadecimal MAC
address of the specified interface (including a hexadecimal number added to the
front of the MAC address to identify the media type).
For example, specifying the client-id ethernet 0/1 (where the Ethernet interface
has a MAC address of d217.0491.1150) defines the client identifier as
01:d2:17:04:91:11:50 (where 01 defines the media type as Ethernet). Refer to
hardware-address <hardware-address> <type> on page 362 for a detailed listing
of media types.
<identifier> Specify a custom client-identifier using a text string (that is converted to a
hexadecimal equivalent) or 7 to 28 hexadecimal numbers (with colon delimiters).
For example, a custom client identifier of 0f:ff:ff:ff:ff:51:04:99:a1 may be entered
using the <identifier> option.
host-name Specifies a text string (to override the global router name) to use as the name in
the DHCP option 12 field.
“<string>” String (encased in quotation marks) of up to 35 characters to use as the name of
the host for DHCP operation.
no-default-route Keyword used to specify that the
Secure Router OS not install the default-route
obtained via DHCP.
no-domain-name Keyword used to specify that the
Secure Router OS not install the domain-name
obtained via DHCP.
no-nameservers Keyword used to specify that the
Secure Router OS not install the DNS servers
obtained via DHCP.
Default Values
client-id Optional. By default, the client identifier is populated using the following formula:
TYPE: INTERFACE SPECIFIC INFO : MAC ADDRESS
Where TYPE specifies the media type in the form of one hexadecimal byte (refer
to
hardware-address <hardware-address> <type> on page 362 for a detailed
listing of media types) and the MAC ADDRESS is the Media Access Control
(MAC) address assigned to the first Ethernet interface in the unit in the form of six
