C9500-24Y4C-A is a managed Layer 3 Cisco Catalyst 9500 Series core and aggregation switch built around 24 fixed SFP28 ports that operate at 1G, 10G, or 25G and four fixed QSFP28 uplinks for 40G or 100G fiber handoff. The platform is Non-PoE, uses a rack-mount 1U form factor, and belongs to the Cisco Catalyst 9500 Series high-performance fixed switch family. Its port design suits fiber aggregation rather than copper endpoint access, with uplinks built into the chassis instead of supplied through an empty modular bay. Network teams place this model where routed fiber density, advanced campus services, route summarization, resilient uplinks, and predictable fixed interfaces matter more than modular access expansion. C9500-48Y4C-A is the closest density sibling, and its documented difference is 48 SFP28 downlink ports instead of 24.
Up to 2.0 Tbps switching capacity supports high-speed aggregation between 25G distribution links and 40G or 100G core paths. Up to 1 Bpps forwarding rate keeps the platform aligned with campus core and collapsed distribution traffic patterns. Network Advantage enables BGP, EIGRP, HSRP, IS-IS, OSPF, PIM, VRF, VXLAN, LISP, MPLS, BGP-EVPN, ISSU, and MACsec-256 where the software release and license conditions support them. C9500-24Y4C-A carries 16 GB DRAM and 16 GB flash for Cisco IOS XE operation, telemetry, automation, and software image storage. Up to 82000 MAC addresses give the switch scale for large routed and switched domains. Management runs through CLI and WebUI on the base network license, with Catalyst Center and Meraki dashboard options tied to Cisco software subscriptions. Automation support includes NETCONF, RESTCONF, gRPC, gNMI/gNOI, YANG, PnP agent, ZTP/Open PnP, and Guest Shell. Fiber-only media keeps the interface plan focused on SFP, SFP+, SFP28, QSFP, and QSFP28 optics selected from the compatibility matrix.
At the enterprise core or distribution tier, this switch aggregates fiber uplinks from Catalyst access switches, routers, firewalls, service appliances, and server-facing aggregation blocks. StackWise Virtual pairs two supported Catalyst 9500 switches into one logical system for multichassis EtherChannel designs, while the 1U chassis fits standard rack rows with high-speed fiber cabling. C9500-24Y4C-A also fits spare-pool planning where operations teams standardize on Catalyst IOS XE and high-performance fiber optics across repeated sites. ORM Systems supplies the switch in new and certified refurbished condition, and refurbished units are checked for boot health, fan and PSU status, port recognition, licensing state, and management access before dispatch.

C9500-24Y4C-A operates in the campus core as the routed handoff between distribution blocks, services networks, and upstream WAN or data center paths. Engineers terminate 25G fiber links on the 24 SFP28 ports, then carry northbound traffic over four 40/100G QSFP28 uplinks. Network Advantage supports advanced routing, segmentation, and high availability features used at this tier, including redundant routed designs and policy separation. The result is a compact core switch that preserves 25G distribution capacity while concentrating uplink bandwidth into fewer high-speed paths.
The switch sits in the distribution layer and aggregates fiber uplinks from access or building switches into a controlled Layer 3 boundary. Network teams map routed interfaces, VLAN trunks, port channels, QoS policies, and redundancy toward the 24 SFP28 ports, then connect core-facing links through 40/100G QSFP28 uplinks. C9500-24Y4C-A keeps the aggregation block fixed and predictable for sites that do not need 48 ports, while retaining Catalyst 9500 operational consistency. The result is cleaner distribution growth with defined routing, uplink capacity, and operational ownership.
Two compatible Catalyst 9500 switches operate as a StackWise Virtual services aggregation point when firewalls, load balancers, routers, or monitoring tools require redundant fiber attachment. Engineers place C9500-24Y4C-A in the shared services block, form multichassis EtherChannel connections, and use Network Advantage features for routing and segmentation between service zones. The 24 SFP28 interfaces support dense 10G or 25G service links, while QSFP28 uplinks return traffic to the core at 40G or 100G. The result is resilient services connectivity without single-chassis dependency.

Cisco C9500-24Y4C-A is a Catalyst 9500 Series fixed core and aggregation switch with 24 SFP28 ports for 1/10/25G connectivity and four QSFP28 uplinks for 40/100G connectivity. It ships with the Network Advantage license level, placing it in Cisco's enterprise campus core and distribution switching portfolio for high-density fiber designs.
C9500 identifies the Cisco Catalyst 9500 Series, 24Y4C identifies 24 SFP28 downlink ports plus four high-speed QSFP uplink ports, and A identifies the Network Advantage license tier. For ordering, C9500-24Y4C-A refers to the Advantage version of the 24-port 1/10/25G Catalyst 9500 high-performance switch in Cisco ordering systems.
C9500-24Y4C-A is a managed Layer 2 and Layer 3 Ethernet switch, not a router, firewall, access switch with copper PoE, or optical transceiver. Its fixed fiber port layout uses SFP28 and QSFP28 interfaces, making the platform suitable for campus core, distribution, aggregation, and high-speed routed handoff roles.
C9500-24Y4C-A sits in the Catalyst 9500 high-performance fixed switching family, above access-layer Catalyst 9200 and 9300 models and below newer Catalyst 9500X systems in bandwidth scale. It targets core and distribution designs that need 25G fiber access into the switch and 100G uplinks toward aggregation or core peers.
C9500-24Y4C-A provides 24 SFP28 ports that support 1G, 10G, and 25G Ethernet operation, plus four QSFP28 uplink ports that support 40G and 100G Ethernet. This mix gives network teams a compact 1RU platform for 25G fiber aggregation with fixed high-speed uplinks and no optional network modules.
C9500-24Y4C-A supports up to 2.0 Tbps of switching capacity and up to 1 Bpps of forwarding performance in Cisco's published Catalyst 9500 performance table. Those figures suit aggregation and core designs where multiple 10G or 25G links feed into 40G or 100G uplinks through Cisco UADP 3.0 hardware.
C9500-24Y4C-A does not provide PoE because its access-facing interfaces are SFP28 fiber ports rather than RJ-45 copper ports. It is normally placed above PoE access switches, where it aggregates uplinks from Catalyst 9200, Catalyst 9300, or similar edge platforms and forwards traffic through routed or trunked fiber links.
C9500-24Y4C-A runs Cisco IOS XE with Network Advantage, so designs use Layer 2 switching, VLANs, QoS, routed access, and advanced routing functions such as BGP, EIGRP, IS-IS, OSPF, HSRP, and multicast routing where licensed and configured. It fits environments that need more than basic Layer 2 aggregation.
C9500-24Y4C-A is managed through Cisco IOS XE using CLI and WebUI for Network Advantage operation, with Catalyst Center and Meraki dashboard options tied to the relevant Cisco software subscriptions. It also supports programmable operations through NETCONF, RESTCONF, gRPC, YANG models, telemetry, and on-box Python capabilities.
C9500-24Y4C-A supports Cisco StackWise Virtual rather than access-switch-style physical stacking. In a StackWise Virtual design, two compatible Catalyst 9500 switches operate as a single logical switching system, and multichassis EtherChannel provides resilient connections toward downstream or upstream devices without building a traditional stack cable ring.
C9500-24Y4C-A is used as a compact campus core or core-adjacent switch where 25G fiber distribution links require 40G or 100G uplink capacity. The Network Advantage tier supports advanced routing and segmentation features, allowing the switch to carry routed VLAN boundaries, redundant uplinks, and policy-aware traffic between major network blocks.
C9500-24Y4C-A fits medium to large enterprise campus environments that need high-speed fiber aggregation without the larger 48-port 25G footprint. The 24 SFP28 ports suit distribution blocks, building aggregation, collapsed-core designs, and selective server or services aggregation where 25G density and 100G handoff matter more than copper endpoint access.
C9500-24Y4C-A suits traffic patterns that combine multiple 10G or 25G fiber uplinks into a smaller set of 40G or 100G paths. Common roles include campus distribution, server access aggregation, WAN edge handoff, network services aggregation, and routed interconnects that need Cisco IOS XE controls and Catalyst operational consistency.
C9500-24Y4C-A is primarily a Catalyst campus core and distribution switch, but its 24 SFP28 ports and four 40/100G QSFP28 uplinks also support selected server access or services aggregation roles. Data center designs should validate optics, buffering, feature requirements, and operational standards against the intended Cisco architecture before selecting this SKU.
C9500-24Y4C-A uses SFP, SFP+, and SFP28 transceivers on the 24 access-facing ports and QSFP or QSFP28 transceivers on the four 40/100G uplink ports, subject to Cisco's transceiver compatibility matrix. Buyers should match speed, reach, fiber type, and connector requirements before ordering optics with the switch.
C9500-24Y4C-A commonly connects to Cisco Catalyst 9300, Catalyst 9400, Catalyst 9500, Catalyst 9600, and compatible Nexus platforms through Ethernet trunks, routed links, or port channels. The exact design depends on optics, interface speed, routing architecture, and whether the switch is serving distribution, core, or aggregation traffic.
C9500-24Y4C-A integrates with common enterprise protocols including 802.1Q VLAN tagging, 802.1X access control, LACP port channels, SNMP, NetFlow telemetry, OSPF, BGP, EIGRP, IS-IS, PIM, VRF, and QoS policies. Network Advantage also adds advanced scale and segmentation functions beyond the Network Essentials feature set for integration with monitoring and automation platforms.
C9500-24Y4C-A supports Catalyst 9500 high-end rack accessories, field-replaceable fan trays, optional SSD storage listed for C9500-24Y4C, and dual 1+1 redundant AC or DC power supply designs. Cisco notes that the switch ships with one power supply by default, with a second supply ordered during purchase or later.
C9500-24Y4C-A and C9500-24Y4C-E share the same 24 SFP28 ports and four 40/100G QSFP uplinks, but the A version uses Network Advantage while the E version uses Network Essentials. C9500-24Y4C-A is the better fit when advanced routing, segmentation, high availability, and larger feature scope are required.
C9500-24Y4C-A provides 24 SFP28 1/10/25G ports, while C9500-48Y4C-A doubles that access-facing fiber density to 48 SFP28 ports. Both models provide four 40/100G uplinks and Network Advantage. The 24-port SKU fits smaller aggregation blocks, while C9500-48Y4C-A fits denser distribution designs with more downstream fiber connections and larger port growth requirements.
C9500-24Y4C-A focuses on 24 SFP28 1/10/25G ports with four 40/100G uplinks, while C9500-32C-A provides 32 QSFP28 ports for 40G or 100G connectivity. C9500-24Y4C-A fits 25G aggregation, while C9500-32C-A fits designs needing more native 100G core-facing interfaces and higher aggregate fiber bandwidth across the core layer.
C9500-24Y4C-A provides 24 SFP28 ports for 1/10/25G operation and four high-speed QSFP uplinks, while C9500-16X-A is a 16-port 10G SFP/SFP+ Catalyst 9500 model with modular uplink options. C9500-24Y4C-A is better aligned to 25G refresh projects and higher uplink bandwidth requirements in newer distribution designs and aggregation closets.
