Discovery; Topology; The Misconfigurations And Optimizations Report - 3Com 3C15500 - Network Director User Manual

HAPTER ISCOVERING THE ETWORK
these relate to 3Com Network Director not being able to retrieve all the
information it requires to accurately depict your network. For example it
may have lost communication with some of the devices during the
discovery process.
The report is divided into two main sections:

Discovery

This section lists any problems encountered in the detecting devices part
of the discovery process. There is a separate sub-section for each subnet
that was discovered. Within each subnet section the report lists the
problems encountered and the devices to which the problems apply. For
instance, it may have failed to determine the write community string for a
device.

Topology

This section lists any problems encountered in the discovering links part
of the discovery process. There is a separate sub-section for each multinet
that it attempted to determine the topology of. Within each multinet
section the report lists the problems encountered and the devices to
which the problems apply. For instance, it may have lost communication
with a device when reading the bridge FDB tables.
Each of the problems listed within the report has a severity level
associated with it, either Warning or Error. For instance, failing to
determine the write community string is considered a warning, since,
although it is required for other areas of 3Com Network Director it is not
essential for discovery. However, a loss of communication is considered an
error since it is likely to adversely affect how 3Com Network Director
depicts your network.
See "Discovery Report Errors and Warnings" on page 144 for a full list of
the possible errors and warnings
The When a discovery operation is complete, 3Com Network Director
Misconfigurations analyses the results in order to establish if any devices have been
and Optimizations misconfigured, or if any improvements could be made to the
Report configuration of your network in order to improve its efficiency. Both the
misconfigurations and improvements (optimizations) are included in the
same report, but in separate sections. If there are no misconfigurations or
if there are no optimizations then the entire corresponding section will be
omitted from the report.
