User permissions for the diagnostic capability and the capture files follow the NTO role-based permissions settings, so that no additional configuration is required to secure the capture files. A web-based RESTful interface is also supported.
The packet capture feature can be enabled from within the NTO 7300 Control Panel GUI by a simple drag and drop onto the desired dynamic filter. The NTO 7300 and IxVision Visibility Architecture provide the most scalable network visibility framework in the industry. The Packet Capture Module is a 48 x 10GE interface card that can be used within a Net Tool Optimizer (NTO) 7300 network packet broker (NPB). Using the built-in decoder, the user can quickly see and understand network problems and events without ever leaving the user interface. The captured files can then be stored on the chassis, saved to the user’s PC, or saved to an external location using SCP or FTP. This pre-event information is often a life saver in reducing the time to diagnosis. Not only can the target packets be captured, but a circular buffer window automatically retains packets preceding the trigger point (i.e., captures what’s still in the buffer) and then the desired packets after that point. This is accomplished using an up to 14GB sampling window at up to 40GE Line rates.
The Packet Capture Module allows IT engineers the ability to capture packets associated with a network anomaly and/or problem, and then quickly analyze the packets to come up with a fast solution. Packet capture (PCAP) analysis is the process of obtaining and analyzing individual data packets that travel through your network.
