ABSTRACT:
The network switch is configured to enable monitoring of switched data. The network switch includes a housing and one or more port cards. Each port card has one or more physical ports and includes switching circuitry to selectively create a communication path between two physical ports. The network switch also includes packet analyzer circuitry, situated within the housing, to monitor data packets switched via a communication path between two physical ports without substantially degrading signal integrity of the data packets.
