address Map Source

1.3.6.1.2.1.16.13.5.1.3

The interface or port on which the associated network address was most recently seen. If this address mapping was discovered on an interface, this object shall identify the instance of the ifIndex object, defined in [3,5], for the desired interface. For example, if an entry were to receive data from interface #1, this object would be set to ifIndex.1. If this address mapping was discovered on a port, this object shall identify the instance of the rptrGroupPortIndex object, defined in [RFC1516], for the desired port. For example, if an entry were to receive data from group #1, port #1, this object would be set to rptrGroupPortIndex.1.1. Note that while the dataSource associated with this entry may only point to index objects, this object may at times point to repeater port objects. This situation occurs when the dataSource points to an interface which is a locally attached repeater and the agent has additional information about the source port of traffic seen on that repeater.
