ABSTRACT:
A method and apparatus for counting Media Access Control (MAC) address moves at line rate is described. According to one embodiment of the invention, a line card in a network bridge receives a frame at a port having a source MAC address that is associated with a different port of the network bridge. The line card signals a control card of the network bridge that the source MAC address has moved. The control card processes the source MAC address move and increments a MAC address move counter. If the MAC address move counter exceeds a MAC address move count threshold for a given time interval, the control card signals each line card in the network bridge to count each frame they receive on any port having that source MAC address. Other methods and apparatuses are also described.
