Debugging the System
Enabling/Disabling System Debugging
The device provides a variety of debugging functions. Most of the protocols and features supported by
the device are provided with corresponding debugging functions. These debugging functions help users
diagnose and troubleshoot the system faults.
The output of debugging information is determined by the following two settings:
z
Protocol debugging setting, which controls whether the debugging information of a protocol is
output.
z
Terminal display setting, which controls whether the debugging information is output to the screen
of a specific user.
The relationship between the two settings is as follows:
