Overview

The Diagnostics page allows you to issue diagnostic commands to the selected Mako and then view the diagnostic results.

The “Packet Capture” diagnostic command allows you to capture packet headers (NOT full packets) as they traverse your network. The captured packet data can be downloaded to your computer as a PCAP file for analysis.

For security purposes, only the first 68 bytes of each packet are captured.
