18.1.3 Configuring Additional DHCP Options
The DHCP Option table lets you configure up to 10 additional DHCP Options that the
DHCP server can use to service the DHCP client. These DHCP Options are included in the
DHCPOffer response sent by the DHCP server.
The following procedure describes how to configure DHCP Options in the Web interface.
You can also configure this using the table ini file parameter, DhcpOption or CLI command,
configure voip > dhcp option.
Note: The additional DHCP Options configured in the DHCP Option table override the
default ones, which are configured in the DHCP Servers table. In other words, if you
configure Option 67 in the DHCP Option table, the device uses the value configured
in the DHCP Option table instead of the value configured in the DHCP Servers table.
 To configure DHCP Options:
1. Open the DHCP Servers page (Configuration tab > VoIP menu > Services > DHCP
Severs).
2. In the DHCP Servers table, select the row of the desired DHCP server for which you
want to configure additional DHCP Options, and then click the DHCP Option Table
link located at the bottom of the page; the DHCP Option Table page opens.
3. Click Add; the following dialog box appears:
4. Configure additional DHCP Options for the DHCP server according to the parameters
described in the table below.
5. Click Submit.
Table 18-4: DHCP Option Table Parameter Descriptions
Parameter Description
Web: Index
CLI: dhcp option
[DhcpOption_Index]
Defines an index number for the new table record.
Note: Each table row must be configured with a unique index.
Web: DHCP Server Index
CLI: dhcp-server-number
[DhcpOption_DhcpServerIndex]
Associates the DHCP Option table entry with a DHCP server that
you configured in ''Configuring the DHCP Server'' on page 205.
Note: Currently, only one DHCP server (Index 0) can be
configured and therefore, this parameter is always set at 0.
Web: Option
CLI: option
[DhcpOption_Option]
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.
Web: Type
CLI: type
[DhcpOption_Type]
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.
