This article describes how to read out the bootlog on switches of the GS-23xx series.


1) Connect to the switch by SSH and log in with admin rights.

Instead of using SSH, you can also connect via a serial console cable as supplied with the switch. 
The required parameters can be found in this Knowledge Base article.

2) Enter the command debug to enter the debug environment.
3) Enter the command show-bootlog to output the bootlog.
