12. **show session id \<session-id\>**: Displays detailed information about a specific session identified by its session ID.
13. **show arp**: Shows the ARP (Address Resolution Protocol) table, which maps IP addresses to MAC addresses, helping troubleshoot connectivity issues.
14. **show running application**: Lists the applications and associated ports detected by the firewall, allowing you to check if the expected applications are being identified correctly.
15. **show jobs all**: Displays the status of any active or recently executed jobs, such as software upgrades or configuration commits.
16. **show high-availability all**: Provides information about the high availability (HA) status and configuration of a firewall cluster, including the active and passive members.
17. **show system logdb-quota**: Shows the utilization of the firewall's log storage, helping you determine if log storage is running low or if any retention policies are causing issues.
18. **test vpn ike-sa gateway \<gateway\>**: Tests the IKE (Internet Key Exchange) security association for a specific VPN gateway, helping diagnose VPN connectivity problems.
19. **clear session all**: Clears all active sessions on the firewall, useful when troubleshooting session-related issues.
20. **request restart system**: Initiates a system restart on the firewall, which can help resolve certain issues. Use this command with caution and only when necessary.
21. **show running resource-monitor follow**: Provides a real-time continuous display of resource utilization statistics, allowing you to monitor CPU, memory, and session information as it updates.
22. **show system state**: Displays the current state of the firewall, including details about the interfaces, routing table, session table, and other relevant system information.
23. **show jobs id \<job-id\>**: Shows the status and details of a specific job identified by its job ID, allowing you to monitor the progress of ongoing tasks.
24. **show running security-policy**: Displays the firewall's current security policy configuration, allowing you to review the configured rules and ensure they match your intended setup.
25. **show running nat-policy**: Provides the current NAT (Network Address Translation) policy configuration, allowing you to verify if traffic is being translated correctly.
26. **show running vpn**: Shows the current VPN (Virtual Private Network) configuration, including details about configured tunnels, gateways, and related settings.
27. **show system disk-space**: Retrieves information about the available disk space on the firewall, helping you identify any storage capacity issues.
28. **show system resources**: Displays the overall resource usage summary, including CPU, memory, and session utilization, as well as the top processes consuming system resources.
29. **debug dataplane packet-diag**: Enables advanced debugging and packet-level diagnostics for the dataplane, helping you troubleshoot traffic flow and packet processing issues.
30. **request support info**: Generates a support information file that includes various logs, configurations, and system information, which can be useful when seeking assistance from Palo Alto Networks support.
31. **show system setting**: Displays the firewall's system settings, including management interface configuration, DNS settings, NTP (Network Time Protocol) server information, and more.
32. **show jobs running**: Lists the currently running jobs on the firewall, providing an overview of any ongoing tasks and their progress.
33. **show session id \<session-id\> detail**: Provides detailed information about a specific session identified by its session ID, including ingress and egress interface, application, and security policy matching.
34. **show routing fib**: Shows the Forwarding Information Base (FIB), which contains the firewall's forwarding table entries, helping diagnose routing issues.
35. **show log system**: Retrieves the firewall's system logs, providing information about system-level events and activities.
36. **show system software status**: Displays the status and information about the installed software on the firewall, including the PAN-OS version, content version, and licensing information.
37. **show running sysd**: Shows information about the system daemon (sysd) process, including CPU and memory utilization, process details, and resource usage.
38. **show user ip-user-mapping all**: Displays the mapping between IP addresses and usernames, helping troubleshoot user-related issues or identify active users on the network.
39. **show system statistics application**: Provides statistics about application usage, including the number of sessions and bandwidth consumed by each application.
40. **debug dataplane pool statistics**: Enables debugging and displays statistics related to memory pools in the dataplane, helping diagnose memory-related issues.
41. **show system logdb-traffic-filter from \<start-time\> to \<end-time\>**: Retrieves traffic logs within a specified time range, allowing you to analyze network traffic during a specific period.
42. **show system state filter \<filter-expression\>**: Displays the system state filtered by a specific expression, enabling you to narrow down the output based on criteria such as process name, module, or log level.
43. **show running security-match from \<source-ip\> to \<destination-ip\> port \<port-number\> protocol \<protocol\>**: Verifies if a specific packet flow matches a security policy based on source IP, destination IP, port, and protocol information.
44. **show session id \<session-id\> forwarding**: Provides forwarding details for a specific session, including the ingress and egress interface, NAT information, and VLAN tags.
45. **show system resources follow**: Displays real-time updates of resource utilization, allowing you to monitor CPU, memory, and session usage as they change.
46. **show routing virtual-router \<vr-name\> protocol bgp summary**: Retrieves a summary of the BGP (Border Gateway Protocol) routing information for a specific virtual router, including the number of peers and their status.
47. **show vpn flow tunnel \<tunnel-name\>**: Displays information about a specific VPN tunnel, including its state, encryption, and authentication settings.
48. **show session all filter destination \<destination-ip\>**: Filters the active session table to display only sessions with a specific destination IP address, helping troubleshoot connectivity to a particular destination.
