ifIndex assignment persistance

The following interfaces have ifIndex assignments that are persistent across reboots and switchover operations:

  • Physical ports
  • Virtual ports
  • Loopback ports
  • Trunk ports
  • IP/GRE tunnels
Note: The ifIndex should be derived from the snIfIndexLookupTable using the InterfaceId (in OID form), instead of assuming that the ifIndex will always stay persistent across reloads.
