Figure 300: Configuring DHCP Relay Service
Enabling DHCP
Dynamic Provision
Use the IP Service > DHCP > Dynamic Provision to enable dynamic provisioning via
DHCP.
Command Usage
DHCPD is the daemon used by Linux to dynamically configure TCP/IP information
for client systems. To support DHCP option 66/67, you have to add corresponding
statements to the configuration file of DHCPD. Information on how to complete
this process are described in
“Downloading a Configuration File and Other
Parameters Provided by a DHCP Server” as described in the CLI Reference Guide .
Some alternative commands which can be added to the DHCPD to complete the
dynamic provisioning process are also described under the
ip dhcp dynamic-
provision command in the CLI Reference Guide .
By default, the parameters for DHCP option 66/67 are not carried by the reply sent
from the DHCP server. To ask for a DHCP reply with option 66/67, the client can
inform the server that it is interested in option 66/67 by sending a DHCP request
that includes a 'parameter request list' option. Besides this, the client can also send
a DHCP request that includes a 'vendor class identifier' option to the server so that
the DHCP server can identify the device, and determine what information should
be given to requesting device.
