Cisco Catalyst C9550 vs C9350: Choose the Right Campus Role
Map C9350 access requirements and an incumbent C9500 design to a C9550 model, then verify software, optics, licensing, failure tests, and rollback before migration.
Campus Segmentation Design: From VLANs to Unified Fabric
Campus segmentation should evolve from VLAN sprawl toward a hierarchy of VRFs, virtual networks, SGTs, and group-based policy that operations teams can actually manage.
Designing an AI-Ready Campus Network After Cisco Live 2026
An AI-ready campus network needs segmentation, telemetry, resilient wired and wireless design, cloud access, identity integration, and a change workflow that can support agentic operations.
Cisco C9550 Smart Switches and the AI-Ready Campus Core
Evaluate the Cisco C9550 against port, scale, redundancy, optics, power, and software requirements; distinguish advertised hardware capability from features supported in the intended deployment.
Catalyst Campus Fabric: eBGP, EVPN, VXLAN, and the Path to Macro and Microsegmentation
Distinguish BGP EVPN campus fabrics from SD-Access, then assess VRF routing separation, supported TrustSec policy, shared failure domains, and validation requirements for a bounded pilot.
