Switch Management and Operating Concepts 31
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 DES-3326 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.
