DGS-3224TG Gigabit Ethernet Switch User's Guide
S
WITCH
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 Chapter 6, "Using the Console Interface"). A network administrator can manage, control and
monitor the switch from the console program.
The DGS-3224TG contains a CPU, memory for data storage, flash memory for configuration data,
operational programs, and SNMP agent firmware. These components allow the switch to be actively
managed and monitored from either the console port or the network itself (out-of-band, or in-band).
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:
