SANET AUTHC failure ???

We are tracking the client's wireless disconnection.

I would like to know what "SANET AUTHC failure" means.

- Following this document https://blogs.cisco.com/networking/new-software-architecture-enables-session-aware-networking-to-massively-scale-authentication-and-access-policy-control , SANET refers to Authentication methods available including 802.1X, Web Authentication, and MAC Authentication Bypass (MAB) , ISE. Therefore you can check (for instance) ISE logs and lookup that particular authentication request for a client and check why it fails. For the clients that disconnect also use client debugging as described in https://logadvisor.cisco.com/logadvisor/wireless/9800/9800ClientConnectivity , you can have client debugs analyzed with : https://cway.cisco.com/wireless-debug-analyzer
This may provide more insights as to the client behavior.

Appendix : - Review your 9800 controller configuration with the CLI command : show tech wireless , have the output analyzed by https://cway.cisco.com/tools/WirelessAnalyzer/ , please note do not use classical show tech-support (short version) , use the command denoted in green for Wireless Analyzer.

Hi Mark,

We are experiencing a similar issue across our environment. When users are docked (wired) and then undock and connect to the corporate Wi-Fi, they often get stuck in a “no internet” state.

On the authentication side, everything looks normal—on Cisco ISE, the user shows as successfully authenticated. However, it appears the client ends up in a stale session conflict after transitioning from the wired docking station to Wi-Fi.

From the controller perspective (Cisco 9800-CL with FlexConnect), the client initially gets stuck in the “IP Learn” policy state. After some time, the device does obtain an IP address, but the “no internet” status remains and the user cannot access any resources.

This issue is recurring across the organization.

We’re looking for a permanent solution to prevent these stale session conflicts during wired-to-wireless transitions.
