- Palo Alto VM Firewall
- Supported PAN-OS
- AWS environment
Cause
- PAN-OS uses "dpdk" library functions to get the link speed and duplex in AWS environment.
- In the "dpdk" code the link speed is set to "NONE" for ena drivers.
- PAN-OS gets these values and display the speed as none.
Resolution
- The behavior is expected as the PAN-OS relies on dpdk drivers to get the speed.
- This issue is only cosmetic and can be ignored.
