Introduction In enterprise NAC deployments, 802.1X authentication on wired ports is not just for Windows machines — it’s equally critical for macOS and Linux endpoints. Whether it’s a corporate MacBook on the marketing team’s desk or a Linux workstation in an R&D lab, Cisco ISE […]

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 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 Wired Endpoint Posture Compliance in Cisco Identity Services Engine (ISE) is where network access control meets endpoint security hygiene. It’s not enough to just identify and authenticate a device — in modern enterprise networks, you must ensure it’s secure before allowing access to sensitive […]

Introduction Wired networks have historically been perceived as more secure than wireless due to their physical nature — you have to “plug in” to access them. However, this illusion of safety has been shattered by insider threats, rogue devices, and BYOD culture. Cisco Identity Services […]

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 Authorization in Cisco ISE is not just about “yes” or “no” access — it’s about what happens after authentication.Once a device or user is authenticated, Cisco ISE decides what level of access they should get: full access, guest access, VLAN assignment, ACL application, dACL, […]

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, […]
Introduction In large networks, managing administrative access to switches, routers, and wireless controllers requires strong authentication, granular authorization, and complete activity logging. This is where Cisco ISE Device Administration via TACACS+ shines — it centralizes control, ensures compliance, and gives security teams full visibility into […]
