      Description

      Steps to reproduce:

      1. Configure a switch device with "Template Module Interfaces SNMPv2" template
      2. Wait for discovery and new triggers created
      3. Plug a temporary device on a port
      4. wait 30s
      5. Unplug the device
      6. Wait for the "Link down" problem to appear

      Result:
      You have now a "Problem" that is sticky with no other way to recover than reconnecting something to that switch port/

      Expected:
      Some way to easily reset the port status.

      One easy way to provide that functionality is to change the following trigger recovery expression from :

      {Template Module Interfaces SNMPv2:net.if.statusifOperStatus.{#SNMPINDEX}.last()}<>2

      to

      {Template Module Interfaces SNMPv2:net.if.statusifOperStatus.{#SNMPINDEX}.last()}<>2 or {Template Module Interfaces SNMPv2:net.if.statusifOperStatus.{#SNMPINDEX}.diff()}=0

      So that one has to simply delete the history for that port to recover the problem.
