Abstract
Methods and apparatus for performing SPAN for a virtual port are disclosed. Specifically, a frame is received from a first port. The frame or a copy thereof is transmitted to a second port, where the second port is identified in a header of the frame. At least one of the first port and the second port is a virtual port. The frame or a copy thereof is also transmitted to a third port, thereby enabling an analyzer coupled to the third port to analyze traffic received by the third port.
