// Health and Status

show [enter]               //Note that output is only non-default values.
show full-configuration   // Show all configurations on the device.
show system interface wan1 | grep -A2 ip // Show WAN and interface information.
get system info admin status // Show logged in users
get system status            // Show system hardware/software update versions
get hardware status          // Detailed hardware model information
get system performance status
get system performance top
show system interface // Interface Configuration
diagnose hardware deviceinfo nic // Interface Statistics/Settings
diagnose hardware sysinfo memory
diag debug crashlog read
diag hardware sysinfo shm     // Device should be in 0, if (>0) then conservemode
get system global | grep -i timer    // Show tcp and udp timers for halfopen and idle
get system session-ttl     // System default tcp-idle session timeout
execute ha manage <devid>    // send heartbeat accross management link.
get hardware nic
diagnose ip address list
get system interface physical

// ARP

diagnose ip arp list

// Track and Troubleshoot
get system session status      // Connection count for ingress/egress
get system session-info full-stat    // Displays session status with breakdown by state
get system session list       // Session list, protocol, expire, src nat, dst nat
diag sys session              // Basic output with no filters of diag sys session
diag sys session filter <option> <value>      // Capture filter based on src, dst, duraction, policy id, vd

// Packet capture

diag debug info     // Displays active debug
diag debug enable     // Enable debug

#diagnose debug flow filter (shows what filters are configured)
#diagnose debug flow filter clear (clear all filter)
#diagnose debug flow filter <options> <value> (configures the filter)
#diagnose debug flow show con enable <show output on console>
#diagnose debug flow show fun enable <show functions>
#diagnose debug flow trace start <number of lines> (to start the trace)
#diagnose debug flow trace stop (to stop the trace)

Example:
diagnose debug reset
diagnose debug enable
diagnose debug flow filter clear
diagnose debug flow filter saddr 192.168.10.1
diagnose debug flow filter dport 80
diagnose debug flow show con enable
diagnose debug flow show fun enable
diagnose debug flow trace start 20

diagnose sniffer packet <interface or ANY> ‘<arguments>’ <level 1-6>

example:
diagnose sniffer packet ANY ‘net 192.168.10.0/24 and not host 192.168.10.1 and port 80 and TCP’ 6

Syn packets only:
diag sniffer packet internal ‘tcp[13] == 2′

to stop:
diagnose debug reset
diagnose debug disable

// Enable packet capture in GUI

System -> Config -> Advanced
Setup packet capture filter, Check box to start, Uncheck to stop.
Download Debug Log

// Show identified devices
diag user device list

// Routes

Interface Up -> Multiple: Select lowest distance -> Dynamic: If same distance choose lowest metric -> Dynamic: If multiple have same distance/metric, depends on protocol -> All “Best Routes” places in table. Match goes to most exact subnet -> Policy routing applied before table lookups.

Route lookups are only for the first packet of each session.
All packets will use same path.
After topology change, routes are flushed and sessions relearned.

get system arp          // ARP Table
get router info routing-table all       // All routing table entries
get router info routing-table details <ip>         // Shows if custom static ordynamic routes exist for dest.
get router info kernel             // Raw kernel routing table
show router static    // Display static routes

execute restore image <firmware_file_name> <TFTP server_ipaddress>    // Restore an image from TFTP
