client-identifier <identifier>
Use the client-identifier command to specify a unique identifier (in dotted hexadecimal notation) for a
Dynamic Host Configuration Protocol (DHCP) client. Use the no form of this command to remove a
configured client-identifier.
Syntax Description
<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).
OR
Specify the hexadecimal MAC address including a hexadecimal number
added to the front of the MAC address to identify the media type.
For example, specifying the
client-identifier
for 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).
For example, a custom client identifier of
0f:ff:ff:ff:ff:51:04:99:a1
may be
entered using the <identifier> option.
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 247 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
hexadecimal bytes. (For units with a single Ethernet interface, the MAC
ADDRESS assigned to ethernet 0/1 is used in this field).
INTERFACE SPECIFIC INFO is only used for frame relay interfaces and can be
determined using the following:
FR_PORT# : Q.922 ADDRESS
Where the FR_PORT# specifies the label assigned to the virtual frame relay
interface using four hexadecimal bytes. For example, a virtual frame relay
interface labeled 1 would have a FR_PORT# of 00:00:00:01.
