Introduction The Self-Registration Portal in Cisco Identity Services Engine (ISE) is a powerful NAC feature that allows visitors to create their own temporary guest accounts before accessing a wireless or wired network. This eliminates the dependency on IT or sponsors for basic guest onboarding, while […]
Introduction Wireless network access control is only as strong as its weakest troubleshooting process. In the real world, even the best-designed Cisco ISE policies fail if engineers cannot quickly diagnose authentication issues, endpoint posture failures, or onboarding errors. Wireless Endpoint Troubleshooting in Cisco ISE is […]
Introduction Guest Wi-Fi is one of the most used features in corporate networks — but also one of the most abused when passwords are poorly managed. Cisco Identity Services Engine (ISE) provides enterprise-grade controls to manage guest credentials in a secure, auditable, and automated manner. […]
Introduction In modern BYOD environments, Android devices represent a significant share of the wireless client base — from personal smartphones to ruggedized enterprise tablets. Unlike iOS, Android devices vary widely by manufacturer and OS version, which means onboarding is not “one-size-fits-all.”Cisco ISE’s BYOD onboarding for […]
Introduction In the enterprise wireless world, security is a game of trust — and trust starts with knowing exactly who is connecting to your network and proving they are who they claim to be. PEAP (Protected Extensible Authentication Protocol) with Cisco ISE is one of […]

Introduction Wireless networks today are the primary access method for employees, guests, and IoT devices — but without proper control, they’re a security nightmare. Users can connect from anywhere, rogue devices can piggyback on open Wi-Fi, and sensitive resources can be exposed in minutes.Wireless 802.1X […]
![[Day 40] Cisco ISE Mastery Training: End-to-End Wired Authentication Lab Validation](https://networkjourney.com/wp-content/uploads/2025/08/Day-40-Cisco-ISE-Mastery-Training-End-to-End-Wired-Authentication-Lab-Validation.png)
Introduction In Cisco ISE deployments, lab validation is not just a “nice to have” — it’s the only way to confirm that your authentication policies work exactly as intended before you deploy them in production.End-to-end wired authentication lab validation means verifying every step of the […]
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 […]
![[Day 38] – Cisco ISE Mastery Training: Wired Supplicant Configuration for Windows](https://networkjourney.com/wp-content/uploads/2025/08/Day-38-–-Cisco-ISE-Mastery-Training-Wired-Supplicant-Configuration-for-Windows.png)
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 […]
![[Day 37] Cisco ISE Mastery Training: Wired Redirection for Non‑Compliant Devices](https://networkjourney.com/wp-content/uploads/2025/08/Day-37-Cisco-ISE-Mastery-Training-Wired-Redirection-for-Non‑Compliant-Devices.png)
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 […]
