Introduction

SmartWare Software Configuration Guide 

This chapter provides a general overview of IP interfaces and describes the tasks involved in their configura-
tion.

An interface is a logical entity that provides higher-layer protocol and service information, such as Layer 3 
addressing. Interfaces are configured as part of a context and are independent of physical ports and circuits. 
The separation of the interface from the physical layer allows for many advanced features. For higher layer pro-
tocols to become active, a physical port or circuit must be bound to an interface. IP interfaces can be bound 
physically to Ethernet, SDSL or Frame Relay ports according to the appropriate transport network layer.

To configure interfaces, perform the tasks in the following sections:

•

Creating an IP interface (see 

•

Deleting an IP interface (see 

•

Setting the IP address and netmask (see 

)

•

ICMP message processing (see 

•

ICMP redirect messages (see 

•

Router advertisement broadcast message (see 

•

Defining the MTU of the interface (see 

)

•

Configuring an interface as a point-to-point link (see 

•

Displaying IP interface information (see 

•

Testing connections with the 

 command (see 

)

Interface names can be any arbitrary string. Use self-explanatory names for your interfaces, which reflect their usage.

Mode: Context IP

node(ctx-ip)[router]#interface name Creates the new interface name, which represents an IP 

interface. This command also places you in interface 
configuration mode for the interface just created.

You are now in the interface configuration mode, where 
you can enter specific configuration parameters for the 
IP interface name.
