Parameter
all: Disable all the debugging.
timeout interval: The interval during which the debugging command is valid.
The
interval value can range from 1 to 1440 minutes.
module-name: Specify the module name.
debugging-option: Debugging option.
Description
Use the debugging command to enable the system debugging. Use the undo
debugging
command to disable the system debugging.
By default, all the debugging processes are disabled.
The Switch provides various kinds of debugging functions for technical support
personnel and experienced maintenance staff to troubleshoot the network.
Enabling the debugging will generate a large amount of debugging information
and decrease the system efficiency. If the
debugging all command is used, it will
adversely affect the operational performance of the network. Use the
undo
debugging all
command to disable all debugging.
By default, if multiple devices form a fabric, the debugging information of the
master is broadcasted within the fabric and the debugging information of the
slave is only displayed on the slave device. You can view the debugging
information including that of the master and the device in which the login port
resides.
You can enable the logging, debugging and trap information switches within the
fabric by executing the i
nfo-center switch-on all command. Synchronization
is a process that each switch sends its own information to the other switches in
the fabric, and meantime receives information from others to update local
information, ensuring the consistency of logging, debugging and trap information
in a fabric.
After the synchronization of the whole fabric, a great deal of terminal display is
generated. You are recommended not to enable the information synchronization
switch of the whole fabric. If you enabled the information synchronization switch,
