example, Ethernet port statistics help you identify network devices that

require high bandwidth, and therefore should be connected through a

dedicated, rather than a shared, network connection. In addition, Ethernet

port statistics help you identify a network device that is the source of

numerous multicast packets due to a possible malfunction.

4.2.1 Gathering Statistics

For purposes of network management, managed objects, such as the

FN100, must be identiﬁed. Creation of a managed object is achieved by

placing its identiﬁer, and a set of management information appropriate to

its class, in the Management Information Database (MIB).

Using the MIB variables, you can obtain a detailed analysis of your

network by combining statistics for each source network, destination

network, and source and destination port. The Fast Network 100 MIB

Reference Guide contains the SNMP MIB variables you need to monitor

and manage the FN100.

4.2.2 System Statistics

For each FN100, the following system statistics are available:

• The number of seconds since the FN100 was last reset.

• The number of spanning tree topology changes that have occurred

since the FN100 was last reset.

• The time since a topology change was last initiated.

• The physical location of the FN100.

• The name and address of the contact person for the FN100.

• The name of the FN100.

• The current number of dynamic (learned) addresses.
