Enabling 802.1X Trace Options on EX Series Switches
You can enable trace options for the 802.1X protocol. The following set of commands enable the writing of trace logs to a file named do1x-log:
user@Policy-EX4300-01# set protocols dot1x traceoptions file dot1x-log user@Policy-EX4300-01# set protocols dot1x traceoptions file size 5m user@Policy-EX4300-01# set protocols dot1x traceoptions flag all
Use the show log
CLI command to display the contents
of the trace log file. For example:
user@Policy-EX4300-01> show log dot1x-log user@Policy-EX4300-01> show log dot1x-log | last 10 | refresh

Attempt authentication with the switch.
Disable authentication tracing.
>netsh ras set tracing * disable
Review the detailed log files under the following directory: C:\windows\tracing.
