In an SD-Access fabric, the Cisco C9800 stops being the wireless data-plane anchor. Client traffic rides the VXLAN overlay from fabric-enabled AP to edge switch. Here is how fabric-mode wireless actually works and why you would adopt it.

Local mode and FlexConnect are the two fundamental ways a C9800 hands off client traffic, and the wrong choice shapes WAN use, failure behavior, VLANs, ACLs, and AAA. A per-site decision framework for wireless designers.

RF punishes shortcuts. Bad AP count, wrong channel plan, or a misjudged power envelope will haunt a wireless design for years. A practical Cisco C9800 RF design guide covering site survey, channel planning, and 2.4, 5, and 6 GHz power tuning.

A working Cisco Catalyst 9800 deployment and a good one are very different things. This guide pulls together the design decisions that matter most, platform, HA, tags, RF, security, and upgrades, with the CLI to validate each.

The Cisco Catalyst 9800 supports model-driven programmability through NETCONF and RESTCONF. A practical guide to automating WLC configuration and retrieving operational data with YANG models on real wireless deployments.

Traditional polling consumes bandwidth and lags reality. Model-Driven Telemetry streams real-time wireless data from the C9800 using YANG and gRPC. A guide to MDT on the Catalyst 9800 for dashboards and operational insight.
