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.
Web Management requires either Microsoft Internet Explorer 4.01 or later or Netscape Navigator 4.03 or
later.
3.3 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 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 switch are
public.
3.4 Protocols
The switch supports the following protocols:
▫
Virtual terminal protocols, such as Telnet
▫
Simple Network Management Protocol (SNMP)
3.4.1 Virtual Terminal Protocols
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.
Note
:
Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal
directly to the console (serial) port.
3.4.2 SNMP Protocol
Simple Network Management Protocol (SNMP) is the standard management protocol for multi-vendor 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.
3.4.3 Management Architecture
All of the management application modules use the same Messaging Application Programming Interface
