Introduction Wireless MAC Authentication Bypass (MAB) is one of the foundational network access control mechanisms in Cisco Identity Services Engine (ISE) — particularly critical in environments where certain wireless devices cannot perform 802.1X authentication (e.g., IoT sensors, IP phones, barcode scanners, printers). Unlike 802.1X, which […]
Introduction In today’s enterprise networks, a single SSID is rarely enough. Organizations often need multiple wireless networks (SSIDs) to segregate traffic and apply different security policies — for example, separating corporate devices, guests, IoT devices, and contractors. However, without a central policy engine, managing authentication, […]

Introduction Dynamic VLAN Assignment (DVA) is a cornerstone capability in Cisco Identity Services Engine (ISE) deployments for wired networks. In traditional environments, VLANs are statically configured on switch ports — meaning every port is tied to a single network segment regardless of who plugs in. […]

Introduction MAC Authentication Bypass (MAB) lets network devices authenticate endpoints by their MAC address when 802.1X fails or isn’t possible (non-802.1X devices such as printers, IP phones, cameras, unmanaged endpoints). In Cisco ISE deployments, MAB is commonly used as a fallback to 802.1X or as […]
Introduction In enterprise networks, controlling who gets access to the wired LAN is as important as controlling wireless access. Cisco ISE provides multiple authentication methods — 802.1X, MAC Authentication Bypass (MAB), and WebAuth — to ensure every device is authenticated, whether it supports 802.1X or […]
![From Zero to Secure: 802.1X + MAB CLI Walkthrough with Labs[CCNP ENTERPRISE]](https://networkjourney.com/wp-content/uploads/2025/06/nj-blog-post-802.1.jpg)
I am going to simplify one of the most powerful port-based access control mechanisms in enterprise networking — 802.1X with MAB (MAC Authentication Bypass). When configured properly, it ensures secure access for both corporate-managed devices and non-802.1X-capable endpoints like printers, IP phones, or legacy hardware. […]
