Console and Telnet Administration Interface
This chapter discusses many of the features used to manage the Switch, and explains many concepts
and important points regarding these features. Configuring the Switch to implement these concepts is
discussed in detail in chapter 6.
The command-line interface (CLI) provides a text-based way to manage and monitor the switch features.
You can access the CLI by using a direct connection to the console port or by using a Telnet or SSH
client. To access the switch by using Telnet or Secure Shell (SSH), the switch must have an IP address
configured on either the service port or the network interface, and the management station you use to
access the device must be able to ping the switch IP address. DHCP is enabled by default on the service
port. It is disabled on the network interface.

Local Console Management
Local console management involves the administration of the Switch via a direct connection to the
RS-232 DCE console port. This is an Out-of-band connection, meaning that it is on a different circuit
than normal network communications, and thus works even when the network is down.
The local console management connection involves a terminal or PC running terminal emulation
software to operate the Switch
’s built-in console program (see Chapter 6). Using the console program, a
network administrator can manage, control, and monitor many functions of the Switch. Hardware
components in the Switch allow it to be an active part of a manageable network. These components
include a CPU, memory for data storage, other related hardware, and SNMP agent firmware. Activities
on the Switch can be monitored with these components, while the Switch can be manipulated to carry
out specific tasks.
3.2
Set Up your Switch Using Console Access
Out-of-band management requires connecting a terminal, such as a VT-100 or a PC running a
terminal-emulation program (such as HyperTerminal, which is automatically installed with Microsoft
Windows) to the RS-232 DCE console port of the Switch. Switch management using the RS-232 DCE
console port is called
Local Console Management
to differentiate it from management done via
management platforms, such as DView or HP OpenView.
Make sure the terminal or PC you are using to make this connection is configured to match these
settings. If you are having problems making this connection on a PC, make sure the emulation is set to
VT-100 or ANSI. If you still don
’t see anything, try pressing <Ctrl> + r to refresh the screen.
First-time configuration must be carried out through a console, that is, either (a) a VT100-type serial data
terminal, or (b) a computer running communications software set to emulate a VT100. The console must
be connected to the Diagnostics port. This is an RS-232 port with a 9-socket D-shell connector and
DCE-type wiring. Make the connection as follows:
1. Obtain suitable cabling for the connection.You can use a null-modem RS-232 cable or an
