Introduction Industrial switches (Cisco IE, Hirschmann, Moxa, Aruba Industrial, etc.) connect PLCs, HMIs, cameras, sensors and other OT gear. These devices rarely support modern endpoint management or 802.1X, are often safety-critical, and require non-disruptive security controls. Cisco ISE becomes the control plane: it identifies OT […]
Introduction Mixed-vendor networks are the reality: Cisco campus switches, Aruba aggregation, Juniper edge, and multi-vendor controllers often coexist. Cisco ISE is commonly used as the central RADIUS/Policy engine — but different vendors implement RADIUS dynamic features (CoA/Disconnect/VSA) and 802.1X behavior with vendor-specific quirks. This masterclass […]
Introduction Mixed vendor environments are the norm — Aruba switches and controllers in some buildings, Juniper edge switches in another, Ruckus controllers in wireless zones, and maybe a small Cisco footprint. Cisco ISE must act as the central RADIUS and policy engine across all of […]
