Default

The device has a set of system-defined command aliases, as listed in Table 1.

Table 1 System-defined command aliases

Command alias

Command or command keyword

access-list acl

end return

erase delete

exit quit

hostname sysname

logging info-center

no undo

Parameters

alias: Specifies an alias, a case-sensitive string of 1 to 20 characters. An alias cannot be alias or

contain spaces.

command: Specifies a command string. Make sure the command string meets the syntax

requirements.

Usage guidelines

System-defined command aliases cannot be deleted.

You can configure one or more aliases for a command or the starting keywords of commands. Then,

you can use the aliases to execute the command or commands. If the command or commands have

undo forms, you can also use the aliases to execute the undo command or commands.

For example, if you configure the alias shiprt for display ip routing-table, you can enter shiprt to

execute the display ip routing-table command. If you configure the alias ship for display ip, you

can use ship to execute all commands that start with display ip:
