Using Telnet

BLADEOS 6.5.2 Application Guide

Note – IPv4 gateway 1 and 2, and IPv6 gateway 1, are used for in-band data networks. IPv4 and IPv6 gateways 3 and 4 are reserved for out-of-band management ports (see “Using the Switch Management Ports” on page 27).

Once you configure the IP address and you have an existing network connection, you can use the Telnet program from an external management station to access and control the switch. Once the default gateway is enabled, the management station and your switch do not need to be on the same IP subnet.

The G8124 supports a menu-based command-line interface (CLI) as well as an industry standard command-line interface (ISCLI) that you can use to configure and control the switch over the network using the Telnet program. You can use the CLI or ISCLI to perform many basic network management functions. In addition, you can configure the switch for management using an SNMP-based network management system or a Web browser.

For more information, see the documents listed in “Additional References” on page 20.

A Telnet connection offers the convenience of accessing the switch from a workstation connected to the network. Telnet access provides the same options for user and administrator access as those available through the console port.

By default, Telnet access is enabled. Use the following commands (available on the console only) to disable or re-enable Telnet access:

RS G8124(config)# [no] access telnet enable

Once the switch is configured with an IP address and gateway, you can use Telnet to access switch administration from any workstation connected to the management network.

To establish a Telnet connection with the switch, run the Telnet program on your workstation and issue the following Telnet command:

telnet <switch IPv4 or IPv6 address>

You will then be prompted to enter a password as explained “Switch Login Levels” on page 38.
