Abstract
Method and apparatus for remote monitoring of data on a communications network, wherein data transmitted and received by a port can be examined at a location other than on the device having the examined port. A method includes the steps of selecting a mirror-from-port of a first device from which to mirror packets, selecting an analyzer port of a second device to which to mirror the packets, and mirroring the packets from the mirror-from-port of the first device to the analyzer port of the second device. The mirroring step may include establishing a connection path through the network, encapsulating the packets with a connection path identifier, and sending the encapsulated packets through the network to the second device. The benefits include ease of use, fewer resources (analyzers) needed, time savings, and not having to dedicate a physical port as the mirror-to-port on the device.
