Configuring an IP Interface

RackSwitch G8000 Application Guide

Configuring an IP Interface

To manage the switch using Telnet, SNMP, or a Web browser, you must configure an IP inter- face. Configure the following IP parameters:

IP address

Subnet mask

Default gateway address

1.Log on to the switch.

2.Enter IP interface mode.

RS G8000> enable

RS G8000# configure terminal

RS G8000 (config)# interface ip 1

3.Configure an IP interface, subnet mask, and VLAN assignment. Enable the interface.

RS G8000 (config-ip-if)# ip address 10.10.10.2				(example IP address)
RS G8000		(config-ip-if)#ip netmask 255.255.255.0
RS G8000		(config-ip-if)# ipvlan 1
RS	G8000	(config-ip-if)#	enable
RS	G8000	(config-ip-if)#	exit

4.Configure the default gateway. Enable the gateway.

RS	G8000	(config)# ip gateway address 10.10.10.1 (example gateway address)
RS	G8000	(config)# ip gateway enable

Once you configure the IP address for your switch and you have an existing network connection, you can use the Telnet program from an external management station to access and control the switch.

The G8000 supports a command-line interface (CLI) that you can use to configure and control the switch over the network using the Telnet program. You can use the CLI to perform many basic network management functions. In addition, you can configure the switch for manage- ment using an SNMP-based network management system or a Web browser.

For more information about using the CLI, refer to the RackSwitch G8000

Command Reference.
