•

Simple Network Protocol Management (SNMP)

Each management method enables the network administrator to configure, manage, and control

the managed switch locally or remotely using in-band or out-of-band mechanisms. Management is

standards-based, with configuration parameters and a private MIB providing control for functions

not completely specified in the MIBs.

Table 2-1.

Comparing Switch Management Methods

•

Out-of-band access via direct cable

connection means network bottlenecks,

crashes, and downtime do not slow or

prevent access

•

No IP address or subnet needed

•

CLI based

•

(HyperTerminal is built into Microsoft

Windows 95/98/NT/2000/XP operating

systems)

Administration Console Interface

The administration console is an internal, character-oriented, VT-100/ANSI command-driven user

interface for performing management activities. Using this method, you can view the

administration console from a terminal, PC, Apple Macintosh, or UNIX workstation connected to

the switch’s console port.

Figure 3-1

shows an example of this management method.

Figure 3-1:

Administration Console Management Method

Set Up Your Switch Using Direct Console Access

The direct access management method is required when you initially set up your switch.

Thereafter, the convenience and additional features of the Web management access method make

it the best method to manage the switch. See

“Web Based Management Overview” on page 4-2

for

more information.

Direct access to the switch console is achieved by connecting the switch’s console port to a

VT-100 or compatible terminal or to a PC, Apple Macintosh, or UNIX workstation equipped with

a terminal-emulation program. This connection is made using the null-modem cable supplied with

the switch.
