Question 1

Q1: Is the Cisco Catalyst 9300 Series backward compatible with Catalyst 3850 stacking?

Accepted Answer

No, the Catalyst 9300 Series uses StackWise-480 technology, which is not compatible with the StackWise-480 or StackWise-160 modules of the Catalyst 3850 Series. Stacking must be performed within the same Catalyst 9300 model family.

Question 2

Q2: How much power per port does the Catalyst 9300 support (PoE/UPoE)?

Accepted Answer

The Catalyst 9300 supports standard PoE (up to 30W per port), UPoE (up to 60W per port), and UPoE+ (up to 90W per port, on supported models). Actual power availability depends on the model and installed power supplies.

Question 3

Q3: What is the maximum stacking bandwidth for the Catalyst 9300?

Accepted Answer

The maximum stacking bandwidth is up to 480 Gbps when using the StackWise-480 technology, allowing up to 8 switches to operate as a single logical unit for simplified management and increased redundancy.

Question 4

Q4: Where can I download the official Cisco Catalyst 9300 datasheet?

Accepted Answer

The official datasheet can be downloaded directly from the Cisco website or via our product page’s “Resources” section.

Question 5

Q5: What software licenses are required for advanced features?
