SNMP management
3.6 Protocols
The Managed Switch supports the following protocols:
 Virtual terminal protocols, such as Telnet
 Simple Network Management Protocol (SNMP)
3.6.1 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 Managed Switch before you can establish access to it with a virtual terminal protocol.
Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal directly
to the console (serial) port.
To access the Managed Switch through a Telnet session:
1. Be Sure of the Managed Switch is configured with an IP address and the Managed Switch is reachable from a PC.
2. Start the Telnet program on a PC and connect to the Managed Switch.
The management interface is exactly the same with RS-232 console management.
3.6.2 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.
