BLADE OS 5.1 Application Guide
BMD00113, September 2009 Chapter 1: Accessing the Switch 27
Using Telnet
By default, Telnet is enabled on the switch. Once you have configured the switch with an IP address
and gateway, you can access the switch from any workstation connected to the management
network using a Telnet connection. Telnet access provides the same options for user and
administrator access as those available through the management module. The switch supports
concurrent Telnet sessions.
To establish a Telnet connection with the switch, invoke the telnet program on your workstation,
followed by the switch IP address:
Using Secure Shell
By default, the Secure Shell (SSH) protocol is disabled on the switch. SSH enables you to securely
log into another computer over a network to execute commands remotely. As a secure alternative to
using Telnet to manage switch configuration, SSH ensures that all data sent over the network is
encrypted and secure. For more information, see “Secure Shell and Secure Copy” on page 54. For
more information on the CLI, see the BLADE OS 5.1 Command Reference.
Using the Browser-Based Interface
By default, the Browser-Based Interface (BBI) is enabled on the switch. The BBI provides access to
the common configuration, management and operation features of the GbE2c through your Web
browser. For more information, refer to the BLADE OS 5.1 BBI Quick Guide.
Configuring BBI Access via HTTP
To enable or disable BBI access on the switch via HTTP, use the following commands:
The management module requires the default HTTP web server port (port 80) to access the BBI.
However, you can change the default Web server port with the following command:
For workstation access to your switch via the Browser-Based Interface, open a Web browser
window and type in the URL using the IP interface address of the switch, such as http://10.10.10.1.
telnet <switch IP address>
>> # /cfg/sys/access/http ena
(Allow BBI access via HTTP)
or
>> # /cfg/sys/access/http dis (Disable BBI access via HTTP)
>> # /cfg/sys/access/wport <x>
