Conclusion
The community strings act like passwords in dealing with the device via SNMP protocol. By changing the
community strings for read / write ('private' in these examples) and read only (public) access, and assigning a
community string to an access IP, an administrator can control access to the FRM220. Community string names
are case sensitive, therefore 'puBlic', 'Public' and 'public' are all different strings.
Now that both the 'System' and 'Manager' settings are complete, the FRM220 is ready to be managed remotely
over an IP network. The system provides a Telnet server feature that allows login over TCP/IP networks and
provides a menu display almost identical to that of the serial console mode. Some functions are disabled in the
Telnet session. For example, you cannot change the FRM220 NMC's IP address from Telnet. To do so would cause
immediate disconnection. However, the individual line card settings remain the same as with serial console.
The FRM220 NMC is supplied with a enterprise MIB file (Management Information Base) that can be compiled
into any standard SNMP network management software. The MIB file is compliant with MIB-II standards.
Later in Chapter 4, we will describe in detail the operation of the Web based management. This graphical
management allows control of many chassis in a convenient and popular WWW environment. The actual
communications between the browser and the NMC card is via standard HTTP protocol.
Set up to 8 trap receivers,
entering their IP addresses.
