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.

with an alias; and you can replace only the second keyword of undo commands with aliases.

format instead of its alias. That is, you can define and use a command alias but the command is not 
saved and restored in its alias.
