3.4 SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMPc Network
Manager, HP Openview Network Node Management (NNM) or What’sup Gold. This management method requires the SNMP
agent on the switch and the SNMP Network Management Station to use the
same community string
. This management
method, in fact, uses two community strings: the
get community
string and the
set community
string. If the SNMP Net-work
management Station only knows the set community string, it can read and write to the MIBs. However, if it only knows the get
community string, it can only read MIBs. The default gets and sets community strings for the Managed Switch are public.

3.5 Administration Console
The administration console is an internal, character-oriented, and command line user interface for performing system
administration such as displaying statistics or changing option settings. Using this method, you can view the administration
console from a terminal, personal computer, Apple Macintosh, or workstation connected to the switch's console (serial) port.
There are two ways to use this management method: via direct access or modem port access. The following sections describe
these methods. For more information about using the console, refer to
Chapter 5 Console Management
.

Direct Access
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a
terminal-emulation program (such as
HyperTerminal
) to the Managed Switch console (serial) port.
When using this management method, a
straight DB9 RS-232 cable
is required to connect the switch to the PC. After
making this connection, configure the terminal-emulation program to use the following parameters:
The default parameters are:
57600 bps
8 data bits
No parity
1 stop bit
