VsiLogicalIfIndex
This textual convention defines a unique value, greater than zero, for each VSI logical interface controlled by the managed system. A logical interface index is an abstract number that is generated and provided by a Slave, and represents a virtual interface. It is used by the Master, when communicating with the Slave, to gain access to interface data, including ifIndex. This is not a selector index for ifType, ifName, ifOperState, and ifAdminState, etc.
