In-Depth Information
Why Do the Wrong Devices or Connections Appear?
Make sure that your routers do not have the same sysName. Routers advertise sysName as their CDP
cache identification, and CWSI Campus depends on CDP information for discovery. Therefore, if you
have two or more devices with the same sysName, CWSI Campus displays unpredictable results.
You can also check the log file to see if a large number of duplicate devices has been discovered and
rejected as duplicates.
Why Do Some Unknown Devices Appear with an OID As the Device Name?
Devices that are unsupported by CWSI Campus will not appear with a device name, but will appear with
an Object Identifier (OID) instead. CWSI Campus attempts to map the OID to a Cisco product tree MIB.
If the OID is under the CiscoProducts or workgroup tree, the OID appears as the device name.
Why Are Frame Relay CDP Links Not Discovered?
Some Frame Relay CDP links may not be discovered by CWSI Campus, even though their neighbors
appear by using the
show cdp
command on the CLI. This is caused by an IOS bug in which
point-to-multipoint Frame Relay WAN links do not appear in the SNMP list of CDP neighbors, even
though they appear on the CLI.
Displaying Discrepancy Reports
Discrepancy reports enable you to discover inconsistencies in your network.
These subsections provide information about working with discrepancy reports.
You can display and print reports about inconsistencies in your network map:
From the CWSI Map window, select Reports; Discrepancies.
The Discrepancy window opens.
Step 1
To print the discrepancy report, select File; Export.
The report is saved as a file. You can print the report from the program in which it has been saved.
Step 2
Interpreting the Discrepancy Report
The discrepancy report displays information on inconsistencies or irregularities in your network.
Table 24-7 describes these irregularities that may appear in your report.
