Cisco C9550-48L4CD | C9550 48-Port 50G Switch, 4x 400G QSFP-DD, Layer 3

Q: What deployment scenarios is the C9550-48L4CD designed for?
A: The C9550-48L4CD is designed for enterprise core and distribution layers in medium to large campus networks. It serves as a consolidation point for multiple 50/25/10/1G SFP access switches, aggregating traffic into a 400/100/40G high-bandwidth backbone. It can also be deployed as a fabric border or aggregation point in fabric network architectures.

Q: What are the uplink configuration options?
A: The switch features four QSFP-DD ports that can be configured as four 100G/40G uplinks or two 400G uplinks, providing flexible high-speed connectivity options for backbone aggregation and core connectivity.

Q: Does the C9550-48L4CD support stacking?
A: Yes, the switch supports next-generation Cisco Smart Stacking with StackWise Virtual technology on all front ports, enabling flexible high-bandwidth stacking configurations for redundancy and simplified management.

Q: What security features are included?
A: The C9550-48L4CD includes integrated security capabilities such as hardware-rooted trust, inline threat protection with Cisco Live Protect, and hardware support for post-quantum cryptography algorithms to protect against emerging quantum-based attacks.

Q: Can applications be hosted directly on the switch?
A: Yes, the switch features an x86 compute platform with AMD quad-core 3.0 GHz CPU, 16 GB DDR5 memory, and up to 960 GB SATA SSD storage, enabling container-based application hosting directly on the switch for edge computing and network automation use cases.
