DETERMINING WHEN TO RELEARN A RELATIONSHIP BETWEEN A NETWORK ADDRESS AND A PORT

A device may receive a packet, via a first port, that identifies a source network address. The device may determine a second port, identified in a data structure, that is associated with the source network address. The second port may be different from the first port. The device may determine an age...

Beschreibung
Zusammenfassung:	A device may receive a packet, via a first port, that identifies a source network address. The device may determine a second port, identified in a data structure, that is associated with the source network address. The second port may be different from the first port. The device may determine an age indicator, stored in the data structure, associated with the source network address and the second port. The device may compare the age indicator to a threshold, and may selectively perform a first action or a second action based on comparing the age indicator to the threshold. The first action may include maintaining, in the data structure, a first indication of a first relationship between the source network address and the second port. The second action may include storing, in the data structure, a second indication of a second relationship between the source network address and the first port.
