Command Alias Configuration
Introduction
As the network environment becomes more complex and network products become increasingly
diverse, users always use network devices from several vendors in real networking environments. In
this case, command keywords differences of devices from different vendors greatly increase the
complexity of device configurations by network administrators.
The command alias function can solve this problem. You can replace the first keyword of a command
supported by the switch with your preferred keyword by configuring the command alias function. For
example, if you configure
show
as the replacement of the
display
keyword for each
display
command,
you can input the command alias
show xx
to execute the
display xx
command. In addition, the original
form of the command
display xx
is still effective.
The command alias function well meets the users’ requirements for preferred form of frequently used
commands, and thus facilitates network configurations as well as respects users' usage habits.

saved and restored in its alias.
