address, it uses the MAC address of the first Ethernet interface to generate its client ID.

Parameters
ascii string: Specifies a case-sensitive ASCII string of 1 to 63 characters as the client ID.
hex string: Specifies a hex string of 4 to 64 characters as the client ID.
mac interface-type interface-number: Uses the MAC address of the specified interface as a DHCP client
ID. The interface-type interface-number argument specifies an interface by its type and number.
Usage guidelines
A DHCP client ID is added to the DHCP option 61. A DHCP server can specify IP addresses for clients
based on the DHCP client ID. You can specify a DHCP client ID by naming an ASCII string or hex string
as the client ID, or by using the MAC address of an interface to generate a client ID. Whichever method
you use, make sure the IDs for different DHCP clients are unique.
Examples
# Specify the hex string of FFFFFFF as the client ID for VLAN-interface 10.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] dhcp client identifier hex FFFFFFFF
