Context
Debugging affects the performance of the system. So, after debugging, run the undo debugging
all command to disable it immediately.
When an Ethernet interface or Eth-Trunk fault occurs, run the following debugging commands
in the user view to locate the fault.
For operation procedures for enabling debugging, refer to Chapter "Monitoring and Debugging"
in the Quidway S9300Terabit Routing Switch Configuration Guide - Device Management. For
the description of the debugging commands, see the Quidway S9300Terabit Routing Switch
Debugging Reference.
Procedure
Step 1 Run the debugging l2if [ error | event | msg | updown ] command to enable the debugging of
link layer features.
