Palo Alto Networks Exam PCNSE Topic 10 Question 105 Discussion

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.
