Configuring A Self-Defined Dhcp Option - H3C S5600 Series Operation Manual

DHCP server parameters such as the IP address and name of a TFTP server, and
bootfile name.
2) After getting related parameters, the DHCP client will send a TFTP request to
obtain the configuration file from the specified TFTP server for system initialization.
If the client cannot get related parameters, it will perform system initialization
without loading any configuration file.
To implement auto-configuration, you need to specify the IP address and name of a
TFTP server and the bootfile name on the DHCP server, but you do not need to perform
any configuration on the DHCP client.
When Option 55 in a client's request contains parameters of Option 66, Option 67, or
Option 150, the DHCP server will return the IP address and name of the specified TFTP
server, bootfile name and an IP address to the client, which uses such information to
complete auto-configuration.
Follow these steps to configure the TFTP server and bootfile name for the DHCP client:
Enter system view
Enter DHCP address pool
view
Specify the TFTP server
Specify the name of the
TFTP server
Specify the bootfile name

2.4.12 Configuring a Self-Defined DHCP Option

By configuring self-defined DHCP options, you can:
Define new DHCP options. New configuration options will come out with DHCP
development. To support new options, you can add them into the attribute list of
the DHCP server.
Extend existing DHCP options. When the current DHCP options cannot meet
customers' requirements (for example, you cannot use the dns-list command to
configure more than eight DNS server addresses), you can configure a self
defined option for extension.
Follow these steps to configure a self-defined DHCP option:
To do...
system-view
dhcp server ip-pool
pool-name
tftp-server ip-address
ip-address
tftp-server
domain-name
domain-name
