Interface Reconfigurations

Device models can potentially reconfigure interfaces at every poll cycle. This reconfiguration increases CPU usage and generates SNMP traffic due to interface table changes or interface stack table changes.

Device models can potentially reconfigure interfaces at every poll cycle. This reconfiguration increases CPU usage and generates SNMP traffic due to interface table changes or interface stack table changes.
To disable interface reconfiguring, do the following:
  • Set the Use_If_Table_Last_Change (0x11f7f) attribute to FALSE to disable interface reconfiguring for an interface table.
  • Set the Use_If_Stack_Last_Change (0x130bc) attribute to FALSE to disable interface reconfiguring for an interface stack table.
You can configure a device model to trigger an alarm if it is continually reconfiguring interfaces. By default, a device model triggers a minor alarm if any one of the following sequences occurs in a 31-minute timeframe:
  • Six interface reconfigurations for an interface table
  • Six interface reconfigurations for an interface stack table
  • Both sequences.
