Cisco C9300X-12Y-E vs C9300X-12Y-A: Network Advantage vs Network Essentials

Jul 22 , 2025 1447

TL;DR: The Cisco Catalyst C9300X-12Y-E and C9300X-12Y-A are the same 12-port 25G switch — the suffix marks the software license: -A = Cisco Network Advantage, -E = Cisco Network Essentials. Pick -A for BGP, EVPN/VXLAN, and SD-Access; -E for standard Layer 2/3 campus work. Both share 12 x 1/10/25G SFP28 ports, modular uplinks, StackWise-1T stacking, and ~1 Tbps capacity. Tested refurbished units of both are in stock with a 3-month warranty.

Same Hardware, Two License Levels

Per Cisco's official Catalyst 9300X documentation, the C9300X-12Y is one hardware platform sold with two license options:

• C9300X-12Y-A — Network Advantage: full enterprise routing (BGP, EIGRP, OSPFv3), EVPN/VXLAN, SD-Access, and complete Cisco DNA Center automation.

• C9300X-12Y-E — Network Essentials: core L2/L3 switching with static routing and OSPF — enough for conventional access and aggregation roles.

Ports, ASIC, memory, power supply, and stacking are identical on both SKUs, so on the used market you are choosing a feature set, not a hardware grade.

Buying Guide: -E or -A?

• C9300X-12Y-E fits aggregation layers, small high-speed pods, and any design that stops at OSPF/static routing — you avoid paying for fabric licenses you will not run.

• C9300X-12Y-A is the right pick when BGP, EVPN/VXLAN, or SD-Access is in your roadmap, or when Cisco DNA Center drives day-to-day operations.

• Used market tip: verify the installed license with show license before purchase; it is factory-set. Refurbished C9300X-12Y-E and C9300X-12Y-A units are in stock, professionally tested, with a 3-month warranty — contact us for best price.

Frequently Asked Questions

What is the difference between C9300X-12Y-E and C9300X-12Y-A?

Only the software license. -E runs Cisco Network Essentials (core L2/L3); -A runs Cisco Network Advantage (adds BGP/EVPN/SD-Access and full DNA automation). The hardware is identical.

What optics work in the C9300X-12Y?

Its 12 SFP28 ports accept 1G SFP, 10G SFP+, and 25G SFP28 optics with auto-negotiation, and the modular slot takes C9300X-NM uplink modules for 25G, 40G, or 100G uplinks.

Can I stack the C9300X-12Y with other Catalyst 9300 switches?

Yes — StackWise-1T allows up to 8 switches in a stack, with StackPower+ for power redundancy, and fans/power supplies are shared across the Catalyst 9300 family.

Is the C9300X-12Y a PoE switch?

No. It is a fiber (SFP28) switch with no PoE. For powered endpoints at multigigabit rates, consider the C9300X-48HX UPOE+ models.
