FAQs

Q: What are the primary use cases for the C9550-64C-XL?
A: The C9550-64C-XL is designed for campus core and distribution layers in very large enterprise networks, fabric border or aggregation roles in SD-Access deployments, and campus edge/gateway deployments requiring high IPv4/IPv6 route scale. It excels as a consolidation point for multiple 100/40G QSFP access switches.

Q: What licensing model does the C9550 Series use?
A: The C9550 Series uses Cisco's Unified Licensing structure through Cisco Networking Subscription or Enterprise Agreement. Licenses unlock platform features and include unified support for both hardware and software. License tiers include Network Essentials and Network Advantage, each providing different feature sets.

Q: Can the C9550-64C-XL support container-based applications?
A: Yes, the switch features an AMD x86 CPU with 8 cores and 32 GB DDR5 memory, supporting up to 960 GB of SATA SSD storage for container-based application hosting. It runs Cisco IOS XE with support for on-box Python scripting, YANG models, and application hosting capabilities.

Q: How does StackWise Virtual work on the C9550-64C-XL?
A: The C9550-64C-XL supports next-generation Cisco Smart Stacking with StackWise Virtual front-side stacking available on all 64 ports. This allows two physical switches to operate as a single logical switch, providing redundancy and simplified management without dedicated stacking cables.

Q: What transceiver types are compatible with the C9550-64C-XL?
A: The 64 QSFP ports support 100G and 40G transceivers including QSFP28 (100G) and QSFP+ (40G) optics. Consult the Cisco Transceiver Module Group (TMG) compatibility matrix for the full list of supported optics, including single-mode, multimode, and direct attach copper (DAC) options.
