User's Manual
Defines an index number for the new table row.
Note: Each row must be configured with a unique index.
Associates the DHCP Option table entry with a DHCP server that
you configured in 'Configuring the DHCP Server' on page 215.
Note: Currently, only one DHCP server (Index 0) can be configured
and therefore, the parameter is always set at 0.
Defines the code of the DHCP Option.
The valid value is 1 to 254. The default is 159.
For example, for DHCP Option 150 (Cisco proprietary for defining
multiple TFTP server IP addresses), enter the value 150.
Defines the format (type) of the DHCP Option value that is
configured in the 'Value' parameter (see below).

[0] ASCII = (Default) Plain-text string (e.g., when the value is a
domain name).

[1] IP address = IPv4 address.

[2] Hexadecimal = Hexadecimal-encoded string.
For example, if you set the 'Value' parameter to "company.com",
you need to set the 'Type' parameter to ASCII.
Defines the value of the DHCP Option. For example, if you are
using Option 66, the parameter is used for specifying the TFTP
provisioning server (e.g., http://192.168.3.155:5000/provisioning/).
The valid value is a string of up to 256 characters. By default, no
value is defined. For IP addresses, the value can be one or more
IPv4 addresses, each separated by a comma (e.g.,
192.168.10.5,192.168.10.20). For hexadecimal values, the value is
a hexadecimal string (e.g., c0a80a05).
You can also configure the parameter with case-sensitive
placeholder strings that are replaced with actual values if the
'Expand Value' parameter (see below) is set to Yes:

<MAC>: Replaced by the MAC address of the client. The MAC
address is obtained from the client's DHCP request. For
example, the parameter can be set to:
http://192.168.3.155:5000/provisioning/cfg_<MAC>.txt

<IP>: Replaced by the IP address assigned by the DHCP server
to the client. For example, the parameter can be set to:
http://192.168.3.155:5000/provisioning/cfg_<IP>.txt
Enables the use of the special placeholder strings, "<MAC>" and
"<IP>" for configuring the 'Value' parameter (see above).

[0] No

[1] Yes (default)
Note: The parameter is applicable only to values of type ASCII (see
the 'Type' parameter above.
