Configuring a DHCP client ID for an interface

1. Enter system view.

system-view

N/A

2. Enter interface view.

interface interface-type interface-number

N/A

3. Configure a DHCP client ID for the interface.

dhcp client identifier { ascii ascii-string | hex hex-string | mac interface-type interface-number }

By default, an interface generates the DHCP client ID based on its MAC address. If the interface has no MAC address, it uses the MAC address of the first Ethernet interface to generate its client ID.

4. Verify the client ID configuration.

display dhcp client [ verbose ] [ interface interface-type interface-number ]

DHCP client ID includes ID type and type value. Each ID type has a fixed type value. You can check the fields for the client ID to verify which type of client ID is used:

• If an ASCII string is used as the client ID, the type value is 00.

• If a hexadecimal number is used as the client ID, the type value is the first two characters in the number.

• If the MAC address of an interface is used as the client ID, the type value is 01.
