IP Address Configuration Guide

IP addressing uses a 32-bit address to identify each host on a network. An example is 01010000100000001000000010000000 in binary. To make IP addresses in 32-bit form easier to read, they are written in dotted decimal notation, each being four octets in length, for example, 10.1.1.1 for the address just mentioned.

If you want to manage a remote Ethernet switch through network management or telnet, you need to configure an IP address for the remote switch and ensure that the local device and the remote switch are reachable to each other.

Networking and Configuration Requirements

As shown in Figure 1-1, a PC connects to a switch through the console port. To manage the switch through Telnet, assign IP address 192.168.0.1 and subnet mask 255.255.255.0 to VLAN-interface 1 of the switch.

Configuration Procedure

# Configure the switch through the console port (omitted).

# Assign the IP address to VLAN-interface 1.

Precautions

Besides directly assigning an IP address to a VLAN interface, you may configure a VLAN interface to obtain an IP address through BOOTP or DHCP as alternatives. If you change the way an interface obtains an IP address, from manual assignment to BOOTP for example, the IP address obtained from BOOTP will overwrite the old one manually assigned.

Sub IP Address Configuration Guide

Network Diagram

Networking and Configuration Requirements

As shown in the above figure, the port in VLAN 1 on Switch is connected to a LAN in which hosts belong to two network segments: 172.16.1.0/24 and 172.16.2.0/24. It is required to enable the hosts in the LAN to communicate with external networks through Switch, and to enable the hosts in the two network segments to communicate with each other.

Configuration Procedure

Assign a primary and secondary IP addresses to VLAN-interface 1 of Switch to ensure that all the hosts on the LAN can access external networks through Switch. Set Switch as the gateway on all the hosts of the two network segments to ensure that they can communicate with each other.

# Assign a primary IP address and a secondary IP address to VLAN-interface 1.

# Set the gateway address to 172.16.1.1 on the hosts in subnet 172.16.1.0/24, and to 172.16.2.1 on the hosts in subnet 172.16.2.0/24.

# Ping Host B from Host A to verify the connectivity.

Precautions

l          You can assign up to seven IP addresses to an interface of the S5600 series Ethernet switches, five IP addresses to that of the S3600 series Ethernet switches and two IP addresses to that of the S5100 series Ethernet switches, the S3100-52P switch. Among these IP addresses assigned for each interface, only one is the primary IP address and the others are secondary IP addresses. A newly specified primary IP address overwrites the previous one.

l          The primary and secondary IP addresses of an interface cannot reside on the same network segment; an IP address of a VLAN interface must not be on the same network segment as that of a loopback interface on a device.
