Cisco TrustSec technology uses Security Group Tags (SGTs) to enforce access controls on Layer 2 traffic. When implementing Zone Protection on a Palo Alto Networks firewall in an environment with Cisco TrustSec, you should configure Ethernet SGT Protection. This setting ensures that the firewall can recognize SGTs in Ethernet frames and apply the appropriate actions based on the configured policies.

The use of Ethernet SGT Protection in conjunction with TrustSec is covered in advanced firewall configuration documentation and in interoperability guides between Palo Alto Networks and Cisco systems.

The CLI command "show system state filter-pretty sys.sl.p8.phy" is used to display detailed physical layer information, which would include the physical media connected to a specific interface such as ethernet1/8. This command is designed to filter the output to show relevant physical layer information for the specified interface.

For more information on Palo Alto Networks CLI commands and their outputs, refer to the "PAN-OS® CLI Reference Guide".

The timer that determines the frequency between packets sent to verify that the HA functionality on the other HA firewall is operational is the Hello Interval. The Hello Interval is the interval in milliseconds between hello packets that are sent to check the HA status of the peer firewall. The default value for the Hello Interval is 8000 ms for all platforms, and the range is 8000-60000 ms. If the firewall does not receive a hello packet from its peer within the specified interval, it will declare the peer as failed and initiate a failover12. References: HA Timers, Layer 3 High Availability with Optimal Failover Times Best Practices

WildFire logs showing a "malicious" verdict with an "allow" action indicate that the initial traffic wasn’t blocked in real-time, likely because the Antivirus profile isn’t configured to act immediately on WildFire verdicts. By default, WildFire submits files for analysis, and signatures may take up to 24 hours to propagate globally unless real-time blocking is enabled. Configuring the Antivirus security profile (Option B) to "block" on malicious WildFire verdicts ensures that threats are blocked within minutes once the verdict is returned (typically 5-15 minutes), leveraging WildFire’s real-time signature updates.

Option A (WildFire analysis profile) defines what files are sent to WildFire but doesn’t control blocking actions. Option C (File Blocking profile) manages file type blocking, not threat verdicts. Option D (file size limits) affects submission eligibility, not blocking behavior. The Antivirus profile is the key to real-time WildFire enforcement, as per Palo Alto Networks documentation.
