FAQs

Q: Can SFP28 ports operate at 1G and 10G?
A: Yes. They support 1G/10G/25G depending on the inserted optics.

Q: Is Front-to-Back airflow suitable for cold aisle placement?
A: Yes. Front-to-Back draws air from the port side to the PSU side, aligning with typical cold-aisle/front orientation.

Q: Does it support EVPN-VXLAN for fabric deployments?
A: Yes. EVPN-VXLAN is supported on AOS-CX for modern data center fabrics.
