This is a unique index for an entry in the agentCosMapIntfTrustTable. A non-zero value indicates the ifIndex for the corresponding interface entry in the ifTable. A value of zero represents global configuration, which in turn causes all interface entries to be updated for a set operation, or reflects the most recent global setting for a get operation.
