Dynamic Host Configuration Protocol
– 645 –
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.
Parameters
These parameters are displayed:
Dynamic Provision via DHCP Status – Enables dynamic provisioning via
DHCP. (Default: Disabled)
Web Interface
To enable dynamic provisioning via DHCP:
1. Click IP Service, DHCP, Dynamic Provision.
2. Mark the Enable box if dynamic provisioning is configured on the DHCP
deamon, and required for bootup.
3. Click Apply.

Configuring the DHCP
Server
This switch includes a Dynamic Host Configuration Protocol (DHCP) server that can
assign temporary IP addresses to any attached host requesting service. It can also
provide other network settings such as the domain name, default gateway, Domain
Name Servers (DNS), Windows Internet Naming Service (WINS) name servers, or
information on the bootup file for the host device to download.
Addresses can be assigned to clients from a common address pool configured for a
specific IP interface on this switch, or fixed addresses can be assigned to hosts
based on the client identifier code or MAC address.
