A chatty endpoint is typically:

  • Repeatedly sending authentication requests (e.g., 802.1X, MAB)
  • Frequently triggering RADIUS transactions
  • Continuously attempting to reauthenticate or reconnect

Common causes

  • Misconfigured supplicant
    • Incorrect 802.1X settings on endpoints (Windows, macOS, etc.)
  • Network instability
    • Flapping ports, unstable Wi-Fi, or switch issues
  • Aggressive timers
    • Very low reauthentication intervals configured on switches or ISE
  • Endpoint behavior
    • IoT devices or printers constantly retrying authentication
  • Posture or profiling loops
    • Devices stuck in posture assessment or profiling cycles

Why?

  • High load on ISE nodes (PSNs especially)
  • Increased RADIUS latency
  • Possible authentication failures for other devices
  • Can lead to performance degradation or even outages in large deployments
