9200L Switch crashed after command

[NicP]

I was trying some commands in a unsourced interface template and with one command it managed to crash my switch.

The template is "dot1q fallback <WORD>" and "no dot1q fallback" 

The logs show that a watchdog timer failover is triggered and the switch reboots itself afterwards.

Switch Ports Model SW Version SW Image Mode
------ ----- ----- ---------- ---------- ----
* 1 28 C9200L-24P-4X 16.9.4 CAT9K_LITE_IOSXE INSTALL

I don't have a service contract so I made this post to address the problem.

Most likely a bug in the IOS you are running is causing the switch to crash. You would need a service contract to be able to open a ticket with TAC and upgrade the IOS.

Thank you Leo,

There is only one thing. In my case it crashed when i configured a unsourced template.
Nevertheless I will try the new software version soon.
