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 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 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.
