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.
