I am not sure if this is the correct place to ask this question but I am interested in setting up alerts for key ports only.  I have setup the example which shows Enabled ports which are currently down:

Tests

Entity Match

However I cannot work out how to refine it further - such as trunk ports only or if the port description contains a string, such as "CORE".  We would like to know when key ports go down only.  I have tried adding:

 ifAlias equals *CORE*

and similar configuration but I expect I have the syntax incorrect.  The idea would be to alert on either ports containing a certain word in their description or on tagged/trunk ports.

I also tried to find a location to search the old emails from this mailing list but have been unable to find it.

Many thanks,

Peter
