General Useful Palo Alto Networks Firewall (PAN-OS) CLI Commands

General system health

show system info –provides the system’s management IP, serial number and code version
show system statistics – shows the real time throughput on the device
show system software status – shows whether various system processes are running
show jobs processed – used to see when commits, downloads, upgrades, etc. are completed
show system disk--space-- show percent usage of disk partitions
show system logdb--quota – shows the maximum log file sizes
debug dataplane internal vif link – show management interface (eth0) counters

Thank you :)

Monitor CPUs

show system resources -- shows processes running in the management plane similar to “top” command
show running resource--monitor – used to see the resource utilization in the data plane, such as dataplane CPU utilization
less mp--log mp--monitor.log – Every 15 minutes the system runs a script to monitor management plane resource usage, output is stored in this file.
less dp--log dp--monitor.log -- Every 15 minutes the system runs a script to monitor dataplane resource usage, output is stored in this file.

General dropped packet troubleshooting

ping source host -- allows to ping from the specified FW source interface
ping host -- ping from the MGT interface
show session all | match – used to show specific sessions in the session table. You can
enter any text after the word match. A good example would be a source or destination IP or an application
show session all | filter destination dest--port -- shows all sessions going to a particular dest IP and port
show session id – shows the specifics behind a particular session by entering the ID number after the word "id”
show counter interface – shows interface counters
show counter global | match drop – used to troubleshoot dropped packets
show counter global delta yes | match [ drop | error | frag ] – show counter changes
since last time ran this command, filter on particular keyword


show running nat--policy-- shows current NAT policy table
show running ippool-- use to see if NAT pool leak
test nat--policy--match – simulate traffic going through the device, what NAT policy will it match?


show routing route – displays the routing table
test routing fib--lookup virtual--router ip -- finds which route in the routing table will be used to reach the IP address that you are testing


show running security--policy – shows the current policy set
test security--policy--match from trust to untrust destination -- simulate a packet going through the system, which policy will it match

PAN Agent

show user pan--agent statistics – used to see if the agent is connected and operational. Status should be connected OK and you should see numbers under users, groups and IPs.
show pan--agent user--IDs -- used to see if the FW has pulled groups from the PANAgent
show user ip--user--mapping – used to see IP to username mappings on the FW
clear user--cache all – clears the user--ID cache
debug device--server reset pan--agent -- reset the firewall’s connection to the specified agent


test url – used to test the categorization of a URL on the FW
tail follow yes mp--log pan_bc_download.log – shows the BrightCloud database update logs
request url--filtering download status – shows the status of the database download (essentially the very last line from the pan_bc_download.log file)
debug dataplane show url--cache statistics– shows statistics on the URL cache
show counter global | match url – shows statistics on URL processing
clear url--cache – used to clear the URL cache-- cache contains 100k of the most popular URLs on this network
show log url direction equal backward-- view the URL log, most recent entries first

To test connectivity to the BrightCloud servers:

 ping host service.brightcloud.com
 ping host database.brightcloud.com

Log viewing / deleting:

show log [ system | traffic | threat ] direction equal backward – will take you to the end of the specified log
show log [ system | traffic | threat ] direction equal forward – will take you to beginning of the specified log
clear log [ traffic | threat | acc ] – clear everything in the specified log

Software, Content, and Licenses

To upgrade the software on the FW:

tftp import software from file
request system software install file
request restart system
request system software [info | check | download | install ] –manipulate PANOS software from the CLI

To upgrade the content on the FW:

tftp import content from file
request content upgrade install file
request content downgrade install previous –downgrade to the previous content version
request system private--data--reset-- to clear config and logs/reports
debug swm [ status | list | revert ] – will show possible code to install, or code that was installed. “revert” is used to revert to last running OS version without having to do a
factory reset (such as from 4.0 to back to 3.1)
request license info – shows the license installed on the device
delete license key ? – use to delete a license file if having issues and want to retrieve new licenses, use question mark to list file names, only delete the files you see fit

Config diff/force/cli format

show config diff-- compares two versions of the config
commit force-- perform a commit, even if there are errors
set cli config--output--format set-- use to view the config  in “set” format from within the configure prompt (#)


To view detailed debug information for IPSec tunneling:
          1. debug ike global on debug
          2. less mp--log ikemgr.log


set deviceconfig setting session tcp--reject--non--syn no – used to ignore SYN when creating sessions; confirm command took effect with show session info
set deviceconfig setting session offload no –-- makes all packets go through CPU, otherwise all fastpath packets just go through EZ chip (turns off session offload to fastpath); confirm command took effect with show session info
debug dataplane pool statistics -- this will show the different dataplane buffers and can e used to see if the system is nearing capacity in certain functionality.
