                    This trigger expression works as follows:
                    1. Can be triggered if operations status is down.
                    2. {$IFCONTROL:"{#IFNAME}"}=1 - user can redefine Context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
                    3. {TEMPLATE_NAME:METRIC.diff()}=1) - trigger fires only if operational status was up(1) sometime before. (So, do not fire 'ethernal off' interfaces.)
                    
                    WARNING: if closed manually - won't fire again on next poll, because of .diff.
