Introduction In enterprise networks, 802.1X authentication is the backbone of Network Access Control (NAC). For a wired connection, the device’s built-in supplicant — a client software that handles authentication — is the bridge between the endpoint and Cisco ISE.Windows systems come with a native 802.1X […]

Introduction In the modern enterprise, it’s not enough to just authenticate a device — we must continuously ensure it complies with corporate policies. Cisco ISE’s Wired Redirection for Non-Compliant Devices enables you to catch endpoints that fail posture checks and redirect them to a remediation […]
Introduction In modern enterprise environments, a single Ethernet port often serves two devices simultaneously: Multi-Domain Authentication (MDA) enables these two devices to authenticate independently using 802.1X or MAB, ensuring role-based access control while maintaining proper VLAN segmentation. Without MDA, your security posture weakens — either […]

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 In enterprise networks, wired access security using 802.1X or MAB can occasionally fail due to endpoint configuration issues, missing certificates, or network downtime. When authentication fails, what happens to the user or device? Without proper handling, devices may be completely cut off from the […]
![[Day 22] Cisco ISE Mastery Training: MAB (MAC Authentication Bypass) Configuration](https://networkjourney.com/wp-content/uploads/2025/08/Day-22-Cisco-ISE-Mastery-Training-MAB-MAC-Authentication-Bypass-Configuration.png)
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 When deploying Cisco ISE in a real-world enterprise, authentication decisions often depend on multiple identity sources—like Active Directory (AD), internal ISE users, LDAP, or RADIUS token servers. But what happens when you need to query them in a specific order? That’s where Identity Source […]
![[Day 16] Cisco ISE Mastery Training: Understanding 802.1X Authentication Flow](https://networkjourney.com/wp-content/uploads/2025/08/Day-16-–-Cisco-ISE-Mastery-Training-Understanding-802.1X-Authentication-Flow.png)
Introduction 802.1X is the foundation of secure wired and wireless network access control in enterprise networks.With Cisco ISE, 802.1X authentication ensures that only authorized devices and users can connect to the corporate network — reducing the risk of data breaches and preventing rogue devices from […]
![[Day 14] Cisco ISE Mastery Training: Setting Up a Test Switch for Authentication](https://networkjourney.com/wp-content/uploads/2025/08/Day-14-Cisco-ISE-Mastery-Training-Setting-Up-a-Test-Switch-for-Authentication.png)
Introduction In Cisco ISE deployments, a Test Switch is your lab’s workhorse. Before rolling NAC (802.1X/MAB) into production, you need a safe environment to test authentication policies, VLAN assignments, and posture checks.This session walks you through configuring a switch from scratch to talk to ISE, […]
