As Internet technologies develop, network devices need to transmit various services, and network administrators often capture packets to locate faults. The packet capture function simplifies the configurations on the packet analysis device and network monitoring device.
With the packet capture enabled, the devices capture the packets matching certain conditions and send these packets to a remote server. The maintenance personnel can run commands to view information about captured packets or save the captured packets to the local storage media as *.cap files. The saved files can be downloaded for fault analysis. This function greatly improves maintenance efficiency and reduces maintenance costs.
