Palo Alto: Useful 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

To 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 <IP_addr_src_int> host <IP_addr_host> — allows to ping from the specified FW source interface
ping host <IP> — 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 <IP> dest–port <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 <VR_name> ip <IP_addr_trying_reach> — 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 <IP>– 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 <name> — reset the firewall’s connection to the specified agent

test url <url or IP> – 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
ping host

Log viewing / deleting1
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 <IP_addr_tftp_server> file <filename>
request system software install file <filename>
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 <IP_addr_tftp_server> file <filename>
request content upgrade install file <filename>
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.
