SWITCH MANAGEMENT CONCEPTS
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 the next chapters.
Local Console Management
Local console management involves the administration of the DES-3225G 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 Interface”). Using the console program, a network
administrator can manage, control and monitor the 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.
Diagnostic (console) port (RS-232 DCE)
Out-of-band management requires connecting a terminal, such as a VT-100 or a PC running 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 done via management platforms, such as D-View, HP OpenView, etc.
The console port is set 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 or ANSI. If you
still don’t see anything, try hitting <Ctrl> + r to refresh the screen.
