1. A method for monitoring network data, the method comprising:
- providing a fiber channel switch module including a fabric crossbar including a network level monitoring section having simultaneous access to traffic flowing among all nodes connected to the fiber channel switch module;
monitoring, by the fiber channel switch module, network traffic;
detecting a trigger event in network traffic between a first node and a second node; and
capturing, in response to detection of the trigger event, select data from network traffic between a third node and a fourth node,the first, second, third, and fourth nodes all being different than each other, andthe trigger event including information from both the first node and the second node.

Abstract
A fiber channel switching module can include an integrated trace buffer memory, a crossbar switch and a control processor disposed on a single line replaceable module (LRM). The trace buffer memory may be adapted to capture selected data traffic transiting the switch fabric based on pre-selected triggers. The selected data can be read out of the trace buffer memory and used for selected diagnostics.

8. A method for continuous network-level monitoring of network data, the method comprising:
-
providing a first fiber channel switch module including a first fabric crossbar including a first network-level monitoring section having simultaneous access to traffic flowing among all nodes connected to the first fiber channel switch module; providing a second fiber channel switch module including a second fabric crossbar including a second network level monitoring section having simultaneous access to traffic flowing among all nodes connected to the second fiber channel switch module; monitoring, by at least one selected from the first network level monitoring section and the second network level monitoring section, network traffic; detecting a trigger event in network traffic, the trigger event including at least one of (i) a first trigger event between a first node and a second node connected to the first fiber channel switch module using the first network level monitoring section, and (ii) a second trigger event between a first node and a second node connected to the second fiber channel switch module using the second network level monitoring section; capturing at least one selected from (i) select data from network traffic between a third node and a fourth node connected to the first fiber channel switch module in response to detection of the first trigger event, and (ii) select data from network traffic between a third node and a fourth node connected to the second fiber channel switch module in response to detection of the second trigger event; and utilizing the second fiber channel switch module as a redundant replacement for the first fiber channel switch module, and, when a failure of the first fiber channel switch module is detected, operating the second fiber channel switch module as the main fiber channel switch module to provide continuous network-level monitoring of network traffic. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system for network-level monitoring of data, the system, comprising:
-
a fiber channel switch module having a fabric crossbar; a controller on the fiber channel switch module; the controller having settable monitoring parameters including one or more triggers adapted to cause the fiber channel switch module to capture selected data from network traffic data flowing through an optical backplane, the fiber channel switch module being adapted to simultaneously monitor traffic flowing to and from each node connected to the fiber channel switch module; and the fiber channel switch module being adapted to monitor network traffic of a first node and detect a trigger event in the network traffic of the first node, the trigger event including information from the first node, and, in response to detection of the trigger event, the fiber channel switch module being adapted to capture select data from network traffic of a second node, the second node being different than the first node. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
