1.3.2 In-Band vs. Out-of-Band
Network management systems are often classified as either in-band or
out-of-band. In-band network management passes data along the same
medium (cables, frequencies) used by all other stations on the network.
An example of an in-band network management system is Cabletron
Systems SPECTRUM.
Out-of-band network management passes data along a medium that is
entirely separate from the network's common data carrier, for example, a
cable connection between a dumb terminal and the COM port of the
MicroMMAC. Cabletron Systems Local Management is an out-of-band
network management system.
A device connected out-of-band to the management agent is not
connected to the LAN. This type of connection allows you to
communicate with a network device even when that device is unable to
communicate through the network, for example, at the time of
installation.
1.3.3 Local vs. Remote Management
Network management applications are usually described as either local or
remote management applications. Local management applications reside
within the circuits of the management device's management agent.
Remote management applications run within the circuits of another
device that provides management services. This allows you to perform
network management from a remote location.
1.4 LOCAL MANAGEMENT REQUIREMENTS
The MicroMMAC provides two communication ports. Each port supports
a management terminal connection. To access Local Management,
connect one of the following systems to either COM 1 or COM 2:
•
Digital Equipment Corporation VT series terminal
•
VT type terminal running emulation programs for the Digital
Equipment Corporation VT series
•
IBM or compatible PC running a VT series emulation software
package
You can also access Local Management using a Telnet connection
through one of the network ports of the MicroMMAC.
