Cisco C9550-24L4CD | C9550 24-Port 50G Switch, 4x 400G QSFP-DD

Q: What uplink configurations does the C9550-24L4CD support?
A: The switch provides four QSFP-DD uplink ports that can be configured as either four 100/40G ports or two 400G ports, offering flexibility for high-bandwidth backbone connectivity to support varying aggregation and core deployment scenarios.

Q: What makes this switch suitable for enterprise core and aggregation deployments?
A: Built on Cisco Silicon One E104 ASIC with 3.2 Tbps throughput, the C9550-24L4CD consolidates multiple 50/25/10/1G SFP access switches into a high-bandwidth 400/100/40G backbone. It supports advanced routing, up to 512,000 IP routes, and provides integrated telemetry and automation capabilities for campus core and distribution layers.

Q: Can this switch run applications directly on the hardware?
A: Yes, the C9550-24L4CD features an x86-based control plane with a 3.0 GHz AMD CPU, 16 GB of DDR5 memory, and up to 960 GB of local SSD storage, enabling container-based applications to run directly on the switch for automation, monitoring, and network services.

Q: What security features are integrated into this switch?
A: The switch includes hardware-rooted trust, integrated threat protection with Cisco Live Protect, and hardware support for post-quantum cryptography algorithms to protect against emerging quantum-based decryption risks. It supports zero-trust security architectures with advanced segmentation and policy enforcement capabilities.

Q: What Layer 2 and Layer 3 features does this switch support?
A: The C9550-24L4CD provides wire-rate IPv4 and IPv6 routing in hardware, multicast routing, flexible Layer 2 and Layer 3 tables, advanced ACLs, NetFlow, and comprehensive QoS. It supports StackWise Virtual for high-availability designs and EVPN/VXLAN for fabric-based campus architectures.
