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 DES-3226 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: 

•  Baud

     9,600 

•  Data

     8

•  Parity:
