Parameters

ascii string: Specifies a case-insensitive ASCII string of 1 to 63 characters as the client ID.

hex string: Specifies a case-insensitive 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

# Use the MAC address of Ethernet 1/2 as the DHCP client ID for Ethernet 1/1.

<Sysname> system-view

[Sysname] interface ethernet 1/1

[Sysname-Ethernet1/1] dhcp client identifier mac ethernet 1/2
