IPLink Software Configuration Guide
5 • Establishing basic IP connectivity
Introduction
This chapter explains how to establish network-based connections to and from your IPLink using IP interfaces
and Ethernet ports. You can configure basic IP connectivity in the context IP and the subsidiary interface com-
mand modes. For a complete description of the IP context and interface configuration related commands
referred to in this chapter, see chapter 10,
“IP context overview”
on page 110, and chapter 11,
“IP interface
configuration”
on page 117.
The chapter includes the following sections:
•
IP context selection and basic interface configuration tasks
•
Examples (see
page 55
)
The predefined IP context in IPLink software contains the functionality of a classic IP router. Within the IP
context, packets are routed between IP interfaces according to the routing table. The following sections guide
you through all the steps necessary to establish network-based IP connectivity to and from your IPLink.
IP context selection and basic interface configuration tasks
The following are the basic tasks involved in configuring an IP context, the related interfaces, and ports:
•
Entering the IP context, creating IP interfaces and assigning an IP address
•
Defining IP Ethernet encapsulation and binding an IP interface to a physical port (see
page 52
)
•
Activating the physical port (see
page 52
)
•
Displaying IP interface information (see
page 53
)
•
Deleting IP interfaces (see
page 54
)
After you have entered the IP context and performed the basic configuration tasks, it is possible to configure
additional protocols and services such as RIP, ICMP, and NAPT for your IP context.
Entering the IP context, creating IP interfaces and assigning an IP address
IPLink software application software running on your IPLink has a predefined IP context, which has to be
selected for the configuration procedure. An IP interface name can be any arbitrary string of not more than 25
characters. Use self-explanatory names for your IP interfaces which reflect their usage. Each IP interface needs
its explicit IP address and an appropriate net mask to be set.

Step
Command
Purpose
1
node(cfg)#context ip router
Enters the predefined IP context configuration
mode.
2
node(ctx-ip)[router]#interface
name
Creates the new interface
name
, which repre-
sents an IP interface. This command also
places you in interface configuration mode
for the interface
name
you have just created.
3
node(if-ip)[name]#ipaddress
ip-address netmask
Sets the IP address
ip-address
and
netmask
netmask for the interface
name
