19. DHCP Client Commands

19-1 ip dhcp client class-id
This command is used to specify the vendor class identifier used as the value of Option 60 for the DHCP
discover message. Use the no form of this command to revert the setting to the default.
ip dhcp client class-id {STRING | hex HEX-STRING}
no ip dhcp client class-id
Parameters
STRING
HEX-STRING

Usage Guideline
Use this command to specify a vendor class identifier (Option 60) to be sent with the DHCP discover
message. This specification only applies to the subsequent sending of the DHCP discover messages.
The setting only takes effect when the DHCP client is enabled on the interface to acquire the IP address
from the DHCP server. The vendor class identifier specifies the type of device that is requesting an IP
address. Option 60 will not be sent with discover messages unless the class identifier is configured for the
interface.
Example
This example shows how to enable the DHCP client, enable the sending of the Vendor Class Identifier,
and specifies its value as VOIP-Device for VLAN 100.
Switch# configure terminal
Switch(config)# interface vlan 100
Switch(config-if)# ip address dhcp
Switch(config-if)# ip dhcp client class-id VOIP-Device
Switch(config-if)#
19-2 ip dhcp client client-id

setting
