Problem Solution
Optivity Switch Manager does not
display all network devices in the
topology map. • Use the ping command to verify that the
network device is connected.
• Choose Edit > Preferences, and verify that the
Automatically Relayout after discovery check box
is selected in the Map section.
• Increase the maximum hop count in the
Preferences dialog box.
Some devices have timed out. View the error log to determine if the timeout is due
to the following, and take the recommended action:
• Invalid read-community string–add the correct
community in the Edit Communities dialog box.
• Slow network–Increase the retry count in the
SNMP section of the Edit Preferences dialog box.
• NMS socket overflow–Set the Max Outstanding
Requests in the SNMP preferences section of the
Edit Preferences dialog box.
