Chapter 4: Switch Management
4.2.2 Modem Access
You can access the switch’s administration console from a PC or Macintosh using an external modem attached to the console
port. The switch management program provides the Console Port screen, accessible from the Basic Management screen that lets
you configure parameters for modem access.

When you have configured the external modem from the administration console, the switch transmits characters that you have
entered as output on the modem port. The switch echoes characters that it receives as input on the modem port to the current
administration console session. The console appears to be directly connected to the external modem.

4.3 Web Management
The switch provides a browser interface that lets you configure and manage the switch remotely.
After you set up your IP address for the switch, you can access the switch’s Web interface applications directly in your Web
browser by entering the IP address of the switch. You can then use your Web browser to list and manage switch configuration
parameters from one central location, just as if you were directly connected to the switch’s console port.

parameters from one central location, just as if you were directly connected to the switch’s console port.
4.4 SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the switch. 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 Network
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 get and set community strings for the switch are public.

4.5 Protocols
The switch supports the following protocols:
Virtual terminal protocols, such as Telnet
A virtual terminal protocol is a software program, such as Telnet, that allows you to establish a management session from a
Macintosh, a PC, or a UNIX workstation. Because Telnet runs over TCP/IP, you must have at least one IP address configured on the
switch before you can establish access to it with a virtual terminal protocol.

switch before you can establish access to it with a virtual terminal protocol.
NOTE: Terminal emulation is different from a virtual terminal protocol in that you must connect a terminal directly to the console
port.
Simple Network Management Protocol (SNMP)
SNMP is the standard management protocol for multivendor IP networks. SNMP supports transaction-based queries that allow
the protocol to format messages and to transmit information between reporting devices and data-collection programs. SNMP
runs on top of the User Datagram Protocol (UDP), offering a connectionless-mode service.

4.6 Management Architecture
All of the management application modules use the same Messaging Application Programming Interface (MAPI). By unifying
management methods with a single MAPI, configuration parameters set using one method (e.g., console port) are immediately
displayed by the other management methods (e.g., SNMP agent of Web browser).

The management architecture of the switch adheres to the IEEE open standard. This compliance assures customers that the switch
is compatible with, and will interoperate with, other solutions that adhere to the same open standard.
