FAQs

Q: Does the C9300X-12Y-A support Power over Ethernet?
A: No, this model does not support PoE. It features 12 data-only SFP28 fiber ports designed for high-speed aggregation and distribution layer applications.

Q: What network modules are compatible with the modular uplink slot?
A: The C9300X-12Y-A supports C9300X-NM series modules including C9300X-NM-2C (2x 100G QSFP28), C9300X-NM-4C (4x 100G), C9300X-NM-8Y (8x 25G SFP28), and C9300X-NM-8M (8x mGig), enabling flexible 40G and 100G uplink configurations.

Q: Can this switch be used as a core or distribution layer device?
A: Yes, with Network Advantage licensing, the C9300X-12Y-A supports advanced Layer 3 routing protocols including BGP, OSPF, EIGRP, MPLS, and LISP, making it suitable for core or distribution roles in enterprise campus networks.

Q: What is StackWise-1T and how does it benefit my deployment?
A: StackWise-1T provides 1 Terabit per second of stacking bandwidth, allowing up to 8 switches to operate as a single logical unit with sub-50ms failover. This delivers exceptional resiliency and simplifies management while supporting up to 96 ports of 25G connectivity in a stack.

Q: Does this switch support Cisco SD-Access?
A: Yes, the C9300X-12Y-A is fully SD-Access capable and can serve as a Fabric Edge, Fabric Border, or Control Plane node. It includes hardware-based VXLAN routing, encrypted traffic analytics, and integration with Cisco DNA Center for intent-based networking.
