debugging-option: Debugging option.
all: Used to disable all debugging.
Description
Use the debugging command to enable system debugging.
Use the undo debugging command to disable system debugging.
By default, all debugging is disabled for the system.
Enabling debugging will generate a great deal of debugging information and thus will
affect the efficiency of the system. Therefore, it is recommended not to enable
debugging for multiple functional modules at the same time. The undo debugging all
command brings great convenience for you to disable all debugging at a time instead of
disabling them one by one.
Related command: display debugging.
Example
# Enable IP packet debugging.
<Quidway> debugging ip packet
IP packet debugging switch is on.
The above command output indicates that the IP packet debugging is enabled.
