This is the command reference for the CloudGenix / Palo Alto ION 1200s.
I couldn't find reliable command information for the ION devices, so I pulled a dump of all the commands from the CLI of a live ION1200 device.
Commands are located in ION1200reference.txt
The easiest way to use this file is to simply Ctrl+F for the command you are looking for.
I've found that the commands are usually named something unintuitive. For example the uptime command is dump device status.
