Packet capture files are not removed even after you disable The pcap-file.fe-0.0.1 file is always the latest file. This process continues until the maximum number of files is exceededĪnd the oldest file is overwritten. When the file named pcap-file.fe-0.0.1 reaches the maximum size again, the file Named pcap-file.fe-0.0.1 reaches the maximum size, theįile is renamed pcap-file.fe-0.0.1.0. Packet captureĬreates multiple files (one per physical interface), suffixing eachįile with the name of the physical interface for example, pcap-file.fe-0.0.1 for the Fast Ethernet interface fe-0.0.1. You name the packet capture file pcap-file. You can specify the target filename, the maximum size of the file,įile creation and storage take place in the following way. Packet capture creates one file for each physical interface. You can specify the maximum size of the packet to be captured, up Including the Layer 2 header is captured and stored in a file. When packet capture is enabled on an interface, the entire packet Packet capture files, and the file permissions.
