Issue/Introduction

Filters were added to the snmpcollector template to exclude some interfaces with the result the template is not getting applied to interfaces it should be applied to. 

Example of the filter rule:

ifPhysAddress => [Condition="Not Equals", Value="0c:c4:7a:56:3e:62"] 

Result is the template is not applied to any interface without a ifPhysAddress, such as a tunnel interface.

 

Cause

The filter 'ifPhysAddress => [Condition="Not Equals", Value="0c:c4:7a:56:3e:62"] ' checks the value of the interface ifPhysAddress and compares it to see if it is 'not equal' to the filter value. However if the interface ifPhysAddress is NULL the interface is ignored and the template is then not applied.




Environment

Release : 9.0.2

Component : UIM - SNMPCOLLECTOR

Resolution

Working as designed. The filter is only applied if the resource item value is not NULL, if the value is NULL, then it is ignored and the template is not applied.
