Switch Management Overview
202-10088-01, March 2005
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
Management Method
Advantages
Disadvantages
Administration
console
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 access to full functionality
(HyperTerminal is built into Microsoft
Windows 95/98/NT/2000/XP operating
systems)
Secure – make sure the switch is installed
in a secure area.
Must be near switch or use dial-up
connection
Not convenient for remote users
Not graphical
Web browser
or Telnet
Can be accessed from any location via the
switch’s IP address
Ideal for configuring the switch remotely

Graphical data available
Most visually appealing
CLI interfaces available
Can be secured via SSL or SSH
May encounter lag times on poor
connections
Displaying graphical objects over a
browser interface may slow navigation

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.
