Cisco Catalyst C9500-32QC-A 32-Port 40G QSFP+ Data Switch, 16x100G QSFP28, Network Advantage
The Cisco Catalyst C9500-32QC-A is a 32-port 40G Layer 3 managed switch with 16x 100G QSFP28 ports. It supports StackWise Virtual and MACsec-256, with Network Advantage.
Overview
The Cisco Catalyst 9500 Series is Cisco's fixed-configuration core and aggregation platform, supporting advanced routing and infrastructure services such as MPLS Layer 2 and Layer 3 VPNs, Multicast VPN, and Network Address Translation, along with Cisco SD-Access capabilities and network system virtualization with Cisco StackWise Virtual that Cisco describes as critical for placement in the campus core. The C9500-32QC is the 32-port 40 Gigabit Ethernet configuration, built on the Cisco UADP 3.0 ASIC, and is configurable as 32 ports of 40G or 16 ports of 100G from the same baseboard. The C9500-32QC-A is that configuration at the Network Advantage tier. Network Advantage is what separates it from the otherwise-identical C9500-32QC-E: Advantage unlocks full dynamic routing and policy-based segmentation, and it is also the tier that enables Cisco StackWise Virtual, which is not available on an Essentials switch. Redundant Platinum-rated power supplies and field-replaceable fans keep it serviceable in an always-on core.
Technical Details
The Cisco Catalyst C9500-32QC-A is a Layer 3 managed 1U rackmount aggregation switch with 32 QSFP+ ports running 40 Gigabit Ethernet, or 16 ports at 100 Gigabit Ethernet and all ports on the baseboard and no separate uplink module, running Cisco IOS XE with the perpetual Network Advantage license. Switching capacity is 3,200 Gbps and forwarding rate is 1,000 Mpps. It carries no Power over Ethernet, so every port is data-only. It is used in the campus core and distribution layer, aggregating downstream access switches and inter-switch uplinks.
Enterprise Network
Corporate Campus
Best For
The C9500-32QC-A suits campus core and distribution layers that aggregate downstream access switches over 32 QSFP+ ports running 40 Gigabit Ethernet, or 16 ports at 100 Gigabit Ethernet. The Network Advantage license fits sites running full dynamic routing such as BGP or IS-IS, policy-based segmentation such as VRF or VXLAN, or a StackWise Virtual pair for high availability.
Not suitable if:
- you only need Layer 2 and basic routed access, since the base Network Essentials tier would be sufficient
- you need to power devices such as wireless access points, IP phones, or IP cameras, since no model in the Catalyst 9500 Series has Power over Ethernet
- you need copper RJ45 ports, since every port on this model is a fiber pluggable slot
- you need a hardened or extended-temperature switch, since this is a standard 1U rackmount model rated for 32 to 104 degrees Fahrenheit

FAQ
Does the Cisco Catalyst C9500-32QC-A support PoE?
No. The Cisco Catalyst C9500-32QC-A carries no Power over Ethernet, and every port is data-only. No model in the Cisco Catalyst 9500 Series offers PoE of any type, so it cannot power devices such as wireless access points, IP phones, or IP cameras. The Catalyst 9500 is a core and aggregation platform, and powered devices are expected to connect to PoE access switches that uplink to it, such as the Cisco Catalyst 9300 Series.
What transceivers does the Cisco Catalyst C9500-32QC-A use?
The Cisco Catalyst C9500-32QC-A provides 32 ports of 40 Gigabit Ethernet QSFP+, or 16 ports of 100 Gigabit Ethernet QSFP28. These are quad SFP slots and do not accept SFP or SFP+ optics directly. There are no copper RJ45 ports on this switch. Specific transceiver compatibility should be verified against the manufacturer's transceiver compatibility matrix at tmgmatrix.cisco.com. Transceivers are sold separately.
Can the Cisco Catalyst C9500-32QC-A be stacked?
The Cisco Catalyst C9500-32QC-A does not form a StackWise data-plane stack of the kind used on the Catalyst 9200 or 9300 Series. At the Network Advantage tier it supports Cisco StackWise Virtual, which pairs two chassis into one logical switch over a StackWise Virtual Link and carries Stateful Switchover and In-Service Software Upgrade across the pair. StackWise Virtual is a Network Advantage capability, so an Essentials switch such as the C9500-32QC-E cannot form a StackWise Virtual pair.
What is the difference between the C9500-32QC-A and the C9500-32QC-E?
The two switches share identical hardware and differ only in license tier. The -E model ships with perpetual Network Essentials, which covers Layer 2 plus routed access such as RIP, EIGRP Stub, OSPF for up to 1,000 routes, PBR, VRRP, and PIM Stub Multicast. The -A model ships with perpetual Network Advantage, which adds full OSPF, EIGRP, BGP, IS-IS, HSRP, BSR, MSDP, and PIM SM, SSM, and BIDIR multicast; network segmentation with VRF, VXLAN, LISP, BGP-EVPN, Cisco TrustSec, SGT, and MPLS; high availability with GIR, NSF, ISSU, and Cisco StackWise Virtual; PTP; and MACsec-256. On the Catalyst 9500, Cisco StackWise Virtual is gated to Network Advantage, so the tier choice decides whether the switch can form a StackWise Virtual high-availability pair.
Does the Cisco Catalyst C9500-32QC-A require a subscription to operate?
No. The switch runs on its included perpetual base license indefinitely. Under Cisco's ordering model, new switch orders include a term-based Cisco DNA or Cisco Catalyst software subscription of the same tier as the network license; that subscription unlocks Cisco Catalyst Center and cloud-managed features. When the subscription term ends, the switch continues operating on the perpetual base license capabilities after a reload.
Is the Cisco Catalyst C9500-32QC-A end of life?
No. Cisco has not published an End-of-Sale or End-of-Life hardware notice for the Cisco Catalyst C9500-32QC-A, and it remains an actively available product. Cisco has published hardware end-of-life bulletins for other members of the Catalyst 9500 Series, covering the C9500-12Q, C9500-24Q, C9500-40X, and C9500-16X and their bundles, but the C9500-32QC is not among them. The other Catalyst 9500 notices cover IOS XE software releases and license offers rather than switch hardware.
What condition is the Cisco Catalyst C9500-32QC-A sold in, and what warranty applies?
The Cisco Catalyst C9500-32QC-A is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
