Switch Management and Operating Concepts
This chapter discusses many of the concepts and features used to manage the switch, as well as the concepts necessary for
the user to understand the functioning of the switch. Further, this chapter explains many important points regarding these
features.
Configuring the switch to implement these concepts and make use of its many features is discussed in detail in the next
chapters.
Local Console Management
A local console is a terminal or a workstation running a terminal emulation program that is connected directly to the switch
via the RS-232 console port on the front of the switch. A console connection is referred to as an ‘Out-of-Band’ connection,
meaning that console is connected to the switch using a different circuit than that used for normal network communications.
So, the console can be used to set up and manage the switch even if the network is down.
Local console management uses the terminal connection to operate the console program built-in to the switch (see the DGS-
3224TGR Command Line Interface Reference manual). A network administrator can manage, control and monitor the
switch from the console program.
The DGS-3224TGR contains a CPU, memory for data storage, flash memory for configuration data, operational programs,
and SNMP agent firmware.
Diagnostic (console) port (RS-232 DCE)
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) a 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 performed via management platforms, such as D-View, HP OpenView, etc.
The console port is set at the factory for the following configuration:
•
Baud rate: 9,600
•
Data width: 8 bits
•
Parity: none
•
Stop bits: 1
•
Flow Control None
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. If you still don’t see
anything, try hitting <Ctrl> + r to refresh the screen.
