Virtual port based span

摘要

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.

主权项

1. In a network device, a method of performing configuration to analyze traffic in a virtual storage area network, comprising:
receiving a first set of configuration information identifying a virtual port for which traffic is to be analyzed, the virtual port being at least one of an ingress port or an egress port, each virtual port associated with a physical port of the virtual storage area network; identifying a destination entity to receive a copy of the traffic to be analyzed; and transmitting frames and a copy of the frames for which the traffic is to be analyzed for the virtual port to the destination entity.
