1 IP Address Configuration

1.1 Introduction to IP Addresses

This section describes the concept of IP addresses.
Each host needs an IP address to communicate with each other on an IP network.
An IP address is a 32-bit address used on the Internet. It consists of a network ID and a host ID.
The network ID identifies a network and the host ID identifies a specific network device on the
network. If multiple network devices have the same network ID, they reside on the same network
regardless of their physical locations.

1.2 IP Address Features Supported by the S9300

This section describes the methods for setting the IP addresses for the S9300.
The S9300 supports the following methods for setting IP addresses:

To save IP address spaces, the S9300 enables you to configure the address mask of an interface
as 31 bits. In this case, there are two IP addresses on a subnet: the subnet address and the broadcast
address of the subnet. Both the addresses are called host addresses.

1.3 Assigning IP Addresses to Interfaces

This section describes the procedure for assigning the IP addresses to interfaces.

1.3.1 Establishing the Configuration Task

1.3.2 Setting a Primary IP Address for an Interface
1.3.3 (Optional) Setting a Secondary IP Addresses for an Interface
1.3.4 Checking the Configuration
1.3.1 Establishing the Configuration Task
Applicable Environment
To run IP services on an interface, you need to set an IP address for the interface. Each interface
of the S9300 can be assigned with multiple IP addresses, in which one is the primary IP address
and the others are secondary IP addresses.
Generally, only one IP address, namely, the primary IP address, is required for an interface. In
special cases, the secondary IP addresses need to be set for the interface. For example, the
S9300 is connected to a physical network through an interface. The hosts on this physical
network belong to two Class C networks. In this case, you need to set a primary IP address and
a secondary IP address on the interface of the S9300. The S9300 can then communicate with all
the hosts on the physical network.
