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.
3.6.3 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 (console port, for
example) are immediately displayable by the other management methods (for example, SNMP agent of Web browser).
The management architecture of the switch adheres to the IEEE open standard. This compliance assures customers that
the Managed Switch is compatible with, and will interoperate with other solutions that adhere to the same open standard.
