Packet capture is a tool that helps you to analyze network traffic and troubleshoot network problems. On a J-series Services Router, the packet capture tool captures real-time data packets traveling over the network, for monitoring and logging.
Packets are captured as binary data, without modification. You can read the packet information offline with a packet analyzer such as Ethereal or tcpdump.
