3.2 Management Access Overview
The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods:
 An administration
console

Web browser
interface
 An external
SNMP-based network management application
The administration console and Web browser interface support are embedded in the Managed Switch software and are available
for immediate use. Each of these management methods has their own advantages. Table 3-1 compares the three management
methods.

3.3 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
