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:
ƒ Virtual terminal protocols, such as Telnet
ƒ 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.
#
Notice:
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 (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
Switch is compatible with, and will interoperate with other solutions that adhere to the same open standard.
