Sep 14, 2019
- Cisco IOS
Known Affected Releases
Symptom: For dot1x switch is sending identity request and getting identity response from supplicant. After getting that response it should be transported via radius to AAA server. But instead switch is clearing the session (posting RESTART). The result is failed dot1x. Conditions: The problem occurs only for Alcatel phones. All phones configured to use EAP-MD5. The problem occurs for both: - Alcatel phones with PC connected - Alcatel phones without PC connected Customer does not have any other phones. PC connected directly does not have that problem. Problem is intermittent, occurs sometimes. We are able to trigger it sometimes by enable/disable "authentication open". Problem occurs on different platforms (3560, 3750) and different versions of software (attached debugs from 15.0.2SE4).
