System Debugging
The Ethernet switch provides a variety of debugging functions. Most of the
protocols and features supported by the Ethernet switch are provided with
corresponding debugging functions. These debugging functions are a great help
for you to diagnose and troubleshoot your switch system.
The output of debugging information is controlled by two kinds of switches:
■ Protocol debugging, which controls whether the debugging information of a
protocol is output.
■ Terminal display, which controls whether the debugging information is output
to a user screen.
The relation between the two switches is as follows:
