The reservation builds an association between the Media Access Control (MAC) address (12
digits, provided in the VCX V7122/SIP documentation) and the IP address. Windows NT
Server provides the IP address based on the VCX V7122/SIP Media Access Control address
in the BootP request frame.
To configure the Microsoft Windows NT DHCP Server to provide boot file information to
BootP clients, edit the BootP Table in DHCP Manager. The BootP Table is located in the
Server Properties dialog box that can be accessed from the Server menu. For information on
editing the BootP Table, view the "BootP Table" Help topic in DHCP Manager.
The following parameters must be entered:
ƒ Local IP address – IP address of your VCX V7122.
ƒ Subnet mask – Set the subnet mask fields to correspond with your network IP address
settings.
ƒ Gateway IP address – The default Gateway IP address.
ƒ Boot File name – Optional; the boot file name normally should not be used. This field is
only used for software upgrade (see “ VCX V7122/SIP Software Upgrade “).
Other TFTP and BootP Servers
Third party TFTP and BootP Servers can be used; for example, Weird Solutions (www.weird-
