Description (partial)

6880 switches running version 15.2(1)SY1 are in VSS and the switch is configured to do dot1x authentication. Dot1x clients are able to authenticate successfully but the active and standby switch are showing the below messages for the standby switch. The below log message is misleading as we know that the radius servers are responding to the active switch. 

*Sep 29 13:45:33.066: %RADIUS-SW2_STBY-4-RADIUS_DEAD: RADIUS server,1646 is not responding.
*Sep 29 13:45:34.066: %SYS-SW2_STBY-3-LOGGER_FLUSHED: System was paused for 4d23h to ensure console debugging output.
*Sep 29 13:45:53.194: %RADIUS-SW2_STBY-3-ALLDEADSERVER: Group MYGROUP: No active radius servers found. Id 1.
