Parameters
all: Enables all debugging functions.
timeout time: Specifies the timeout time for the debugging all command. When all debugging is enabled,
the system automatically executes the undo debugging all command after the timeout time. The time
argument is in the range of 1 to 1440 minutes.
module-name: Specifies a module by its name, such as arp or device. To display the current module
name, use the debugging ? command.
option: Specifies the debugging option for a module. The option number and content differ for different
modules. To display the supported options, use the debugging module-name ? command.
Usage guidelines
Output of debugging commands is memory intensive. To guarantee system performance, enable
debugging only for modules that are in an exceptional condition.
