Table 56 Optivity Switch Manager problems and solutions

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.
