show auth-tracebuf
show auth-tracebuf [count <1-250] [failures] [mac <address>]
Description
Show the trace buffer for authentication events.
Syntax
Parameter Description
count <1-250>
limit the output of the command to the specified number of packets.
failures
Filter the output of this command to display only authentication failures
mac <address>
Filter the output of this command to display only information for a specified
MAC address.
Usage Guidelines
Use the output of this command to troubleshoot 802.1X authentication errors. Include the <address>
parameter to filter data by the MAC address of the client which is experiencing errors. This command can tell
you, for example, when 802.1X authentication completed and when keys were plumbed correctly.
Example
The example below shows the most recent ten trace buffer entries for the controller. Each row includes the
following information:
(host) # show auth-tracebuf count 10
