0.12.x firmware is required to capture beacon frames. With older firmware less than 0.10.x, ‘local capture’ option must be selected.
APs must run 0.10.x firmware or newer for streaming functionality. Streaming PCAP is available for the Wired and Wireless interfaces on Access Points within a site. Wired Streaming PCAP captures from the eth0 interface on the APs. Wireless Streaming PCAP performs radiotap capture from the data radios, without taking the radios out of service.
#Wireshark pcap file analysis manual#
We have added pre-canned filters for commonly captured packet types as well as continue to allow manual tcpdump expressions to be used for advanced captures. The trailing 20MB of a PCAP will be saved to file. Once the packet capture is stopped or completes, a PCAP file will be generated which can be downloaded and opened in something like Wireshark for detailed analysis. The UI can be used for basic analysis, with a variety of display columns and filtering available.
Streaming PCAP eliminates the uncertainty because packets are streamed to the UI in realtime. With the previous manual packet capture, one couldn’t be sure they were actually capturing the desired packets. Once the PCAP is completed, a full PCAP file will be generated which can be downloaded and opened in a packet analysis tool such as Wireshark for detailed analysis. This week we are introducing an improved mechanism for manual packet captures, where packets are live streamed into UI for realtime analysis.
