1.3 Configuring IP Addresses for Interfaces

Assigning an IP address to a device on a network enables the device to communicate with the
other devices on the network.

1.3.1 Establishing the Configuration Task

This section describes the applicable environment, pre-configuration tasks, data preparation, and
configuration procedure for assigning an IP address to an interface.
Applicable Environment
To start IP services on an interface, configure the IP address for the interface. You can assign
several IP addresses to each interface. Among them, one is the primary IP address and the others
are secondary IP addresses.
Generally, you need to configure only a primary IP address for an interface. Secondary IP
addresses, however, are required in some cases. For instance, when a device connects to a
physical network through an interface, and computers on this network belong to two Class C
networks, you need to configure a primary IP address and a secondary IP address for this interface
to ensure that the device can communication with all computers on this network.
Pre-configuration Tasks
Before configuring an IP addresses for an interface, complete the following tasks:
