Question # 42

Certain services in a customer implementation are not working, including Palo Alto Networks Dynamic version updates. Which CLI command can the firewall administrator use to verify if the service routes were correctly installed and that they are active in the Management Plane?

debug dataplane internal vif route 255

show routing route type management

debug dataplane internal vif route 250

show routing route type service-route

Full Access

Answer:

Explanation:

When troubleshooting Palo Alto Networks services, such as dynamic updates, verifying the status of service routes is critical. Service routes determine how the firewall communicates with external services (e.g., Palo Alto Networks update servers, WildFire, DNS, etc.) from the Management Plane or data plane interfaces.

Why "debug dataplane internal vif route 250" is Correct

Purpose of the Command:

This command allows administrators to view the service routes configured on the firewall and verify if they are installed correctly and actively working.

The number 250 specifically refers to service routes in the Management Plane.

Output:

The command displays detailed information about service routes, including routing decisions, source interfaces, and next-hop IPs.

Helps identify issues such as:

Incorrect interface configuration.

Invalid next-hop IPs.

Missing routes for specific services.

Analysis of Other Options

debug dataplane internal vif route 255

Incorrect:

The number 255 does not correspond to service routes but is used for internal route debugging unrelated to management plane service routes.

show routing route type management

Incorrect:

This command does not exist in PAN-OS CLI. It might be a misrepresentation of another command.

debug dataplane internal vif route 250

Correct:

As explained above, this is the correct command for verifying service routes in the Management Plane.

show routing route type service-route

Incorrect:

This is not a valid PAN-OS CLI command.

PAN-OS Documentation Reference

Service Routes in PAN-OS 11.0:

The configuration and verification of service routes are covered under the Device > Setup > Services section of the GUI.

For CLI, the debug dataplane internal vif route 250 command is specifically used for troubleshooting service routes in the Management Plane.

For more details, refer to:

PAN-OS 11.0 CLI Guide: Covers debugging tools and service route verification.

PCNSA Study Guide: Domain 1 includes service route configurations and their importance in maintaining connectivity for management services.
