3.5 SNMP-Based Network Management

You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMPc Network
Manager, HP Openview Network Node Management (NNM) or What's Up Gold. 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 Managed Switch are public.

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.
