Command Mode
Interface Configuration (VLAN)
Command Usage
• Use this command without any keyword to restore the default setting.
• This command is used to identify the vendor class and configuration of the switch to the DHCP
server, which then uses this information to decide on how to service the client or the type of
information to return.
• The general framework for this DHCP option is set out in RFC 2132 (Option 60). This
information is used to convey configuration settings or other identification information about a
client, but the specific string to use should be supplied by your service provider or network
administrator.
• The server should reply with Option 43 information, which encapsulates Option 66 attributes
including the TFTP server name and boot file name.
Example
Console(config)#interface vlan 2
Console(config-if)#ip dhcp client class-id hex 0000e8666572
Console(config-if)#
Related Commands

This command submits a BOOTP or DHCP client request.
Default Setting
None
Command Mode
Privileged Exec
Command Usage
• This command issues a BOOTP or DHCP client request for any IP interface that has been set to
BOOTP or DHCP mode through the
ip address command.
• DHCP requires the server to reassign the client’s last address if available.
• If the BOOTP or DHCP server has been moved to a different domain, the network portion of the
address provided to the client will be based on this new domain.
Example
In the following example, the device is reassigned the same address.
Console(config)#interface vlan 1
Console(config-if)#ip address dhcp
Console(config-if)#exit
