The IP protocol defines and routes datagrams across the network and provides connectionless
transport service. It uses packet switching and makes a best effort to deliver its packets. The IP
protocol uses the services of the data-link layer to accomplish the actual transmission.
The IP protocol was designed to handle the interconnection of the vast number of internet WAN
and LAN networks. The SFVRA-CFG's IP network information defines how an IP network will
interconnect. The network interface information you configure defines a system's network
connections. The static route information you configure defines routes to networks across a WAN,
or to LAN networks through a router that does not support IP RIP.
You can configure or view IP network information in one of two ways: at the subnet level or at the
system level. The subnet view looks at IP network information with the "big picture" in mind; you
are viewing how multiple systems interconnect to form a subnet. The system view looks at IP
information with a specific system in mind; you are viewing how the individual system relates to
the rest of the network.
Depending on which view you will be using to add IP network information, refer to one of the
following two sections for instructions:
•
Configuring IP Network Subnet Information
•
Configuring IP Network System Information
Both views share basic concepts. These concepts are described in
Note:
Although you cannot currently use SFVRA-CFG to configure IP filters, you may use the
device's CFGEDIT utility to configure filters. You can then go back to using SFVRA-CFG
as your configuration tool as long as you have made no other changes using CFGEDIT. At the
end of this chapter we provide special information regarding configuring

Regardless of how you add IP network information, there are two main concepts you need to
understand: network interfaces and static routes. In the following sections, we provide an overview
of each concept.

Network interfaces are the connections of a system to a data network. For example, the Ethernet
resource provides a network interface to a Ethernet LAN. The ISDN lines provide network
interfaces to multiple remote networks. Because of their switched nature, the ISDN lines provide
virtual network interfaces. That is, the same physical ISDN line can actually connect to different
remote networks by dialing a different phone number.
The following diagrams provide examples of each interface type. The variety of network interfaces
available allow you to install a wider range of devices at the remote sites.
