Purpose

The ISE Linux component documents the complete methodology for deploying 802.1X EAP-TLS authentication on Linux workstations against Cisco ISE. This is the largest ISE-focused spoke in the ecosystem, covering PKI certificate enrollment via HashiCorp Vault, NetworkManager 802.1X supplicant configuration, Active Directory integration, ISE policy set design, and posture compliance.

The documentation serves as both a production runbook for CHLA and a reference implementation for any enterprise deploying Linux 802.1X with ISE.
