Introduction In enterprise networks, downtime is unacceptable. Whether you are protecting a hospital’s patient data, a bank’s financial records, or a defense network’s classified systems, Cisco ISE (Identity Services Engine) must be available 24×7 with zero disruption. A single node failure in an ISE cluster […]
Introduction Wired networks still carry most enterprise East/West traffic, printers, IP phones, scanners, and user PCs. Cisco TrustSec replaces sprawling IP/VLAN ACLs with Security Group Tags (SGTs) and role-based enforcement. With ISE assigning SGTs at the port during 802.1X/MAB, your Catalyst switches can tag traffic […]

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, 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 […]
