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.
Cisco Live 2026 Lab Build: A Small-Scale Reference Architecture
A small-scale lab architecture for testing Cisco Live 2026 ideas: segmentation, SD-WAN concepts, Secure Access patterns, telemetry, AgenticOps workflows, and change validation.
Branch Network Design for the AI Era
AI-era branch design needs SD-WAN, SSE, secure access, local resilience, application steering, Wi-Fi capacity, segmentation, and experience telemetry.
A Practical Post-Quantum Readiness Checklist for Network Teams
A practical checklist for network teams preparing for post-quantum cryptography: inventory, risk ranking, platform support, certificates, VPNs, secure boot, and refresh planning.
Resilience Planning for Cisco Networks: Patch, Shield, Replace, or Segment
A practical resilience model for Cisco networks should classify each exposure into patch, shield, replace, or segment, with owners, deadlines, and evidence.
Designing ThousandEyes Visibility Across Branch, Cloud, and SaaS

Cisco SD-WAN to Multicloud Fabric: A Migration Design
A phased migration from SD-WAN and native cloud networking to Cisco Multicloud Fabric should start with inventory, routing domains, security policy, pilot paths, and measurable experience.
Implementing AgenticOps Safely: Human Approval, Audit Trails, and Rollback
Agentic network operations need guardrails: approved action classes, human review, role limits, dry runs, rollback plans, and audit trails before any production change.
Building a Network Digital Twin Workflow
A network digital twin is useful when it models topology, intent, policy, dependencies, and change impact. Here is a practical workflow for using it safely.
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.
