Patent ID: 7764695

Claim:
A network analyzer comprising: a first chassis; a second chassis; wherein the first and second chassis each include one or more blades and each blade includes one or more ports; an interconnector coupled to the first and second chassis for interconnecting the first and second chassis such that at least some of the ports of the first and second chassis are configured to form a trigger group; and a microprocessor accessible by the first and second chassis, wherein the network analyzer is configured such that executing software with the microprocessor configures the trigger group to perform the following: an act of generating an arm condition at a first port of the first chassis that is part of the trigger group; an act of transmitting the arm condition to one or more additional ports of the first chassis that are part of the trigger group while not transmitting the arm condition to the ports of the second chassis that are part of the trigger group such that not all ports of the trigger group receive the arm condition; an act of limiting detection of a triggering condition to those ports that have received the arm condition; an act of generating a rollback condition on a second port of the first chassis that is part of the triggergroup; and an act of transmitting the rollback condition to one or more of those ports that have received the arm condition while not transmitting the rollback condition to the remaining ports that have received the arm condition such that not all ports that received the arm condition receive the rollback condition, wherein those ports that receive the rollback condition are no longer configured to detect the triggering condition defined by the arm condition.
