Description of the problem

An OSN3500 network element with ID 9-37 can be displayed in the physical topology tree under the U2000 main topology current view interface, but it cannot be found in the background map on the right, which makes it inconvenient to maintain the network element.

Process

Under normal circumstances 9-37 should be displayed in the background image as follows.

1, the physical topology tree under the current view interface of the network administrator is normal statistics 9-37 network element information, using Ctrl + F can also be found in the network element, indicating that this network element information has been successfully created in the U2000 above. U2000 network element view interface has a display function is filtered, filtered content of the U2000 is not displayed, we check and find that all the checkboxes are ticked to exclude the U2000 filtered the network element information, as shown in the figure: U2000 filtered the information, as shown in the figure: U2000 filtered the network element information, as shown in the figure: U2000 filtered the network element information, as shown in the figure: U2000 filtered the network element information. U2000 filtered the network element information, as shown.

2, double-checking found in the lower part of the figure above there is another condition of the filtering options, check to find that there is a secondary filter here.

3, clear the name of the network element 4444S information, click on the filter, 9-37 network elements successfully displayed in the main topology background map, the problem is solved.

Root Cause

Use the U2000 filtering function to filter out the network element information, resulting in the background map does not show the network element.

Suggestion and Summary

The purpose of the filter menu itself is when the number of network management objects, in order to quickly locate the use of topology view filtering function, according to the object category of the view on the display of the object filtering, to achieve the purpose of precision, but this function should be used with caution, to avoid the occurrence of a similar case and is still not clear where the cause of the problem.
