With a switching capacity of 6.4 Tbps and a forwarding rate of 2.4 Bpps, the Catalyst 9500 C9500-48Y4C-A delivers line-rate performance across all ports, enabling high-speed data center and campus core deployments without bottlenecks. This Cisco enterprise-class switch combines density, throughput, and advanced security in a compact 1RU fixed configuration, making it the ideal choice for network engineers building scalable, high-performance infrastructure.
The C9500-48Y4C-A features 48 SFP28 downlink ports supporting 1G, 10G, or 25G speeds, plus 4 QSFP100 uplink ports for 40G or 100G connectivity—delivering flexible multi-speed architecture. Hardware-accelerated MACsec encryption runs at line-rate on all ports using 256-bit AES (IEEE 802.1AE), ensuring encrypted traffic moves at wire speed without performance penalty. The Cisco UADP 3.0 ASIC powers advanced services including VXLAN EVPN, full routing protocol support (BGP, OSPF, IS-IS, EIGRP, PIM Multicast), and comprehensive programmability via NETCONF, RESTCONF, gRPC, and streaming telemetry. Redundant hot-swappable power supplies and flexible airflow options ensure high availability and operational simplicity in any data center environment. Management integration spans Cisco DNA Center, CLI, SNMP, Syslog, and NetFlow/IPFIX for unified visibility and control. For network architects and IT infrastructure teams evaluating enterprise switch platforms, part number CISCO-C9500-48Y4C-A-CATALYST-9500-48-25G represents a proven, standards-compliant solution with Cisco IOS XE and Catalyst 9500 series heritage.
