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 doing one of the following operations:
• Naming an ASCII string or hex string as the client ID.
• 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
# Use the MAC address of GigabitEthernet 2/1/2 as the DHCP client ID for GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] dhcp client identifier mac gigabitethernet 2/1/2
