Global configuration mode
From the alias configuration mode—which you access by entering this command—you can manage global aliases. From that mode, you can also access the user-alias configuration mode for a specified user, from which you can manage aliases for that user.
To delete all global aliases, use the no alias-config alias form of this command.
To delete all aliases defined for a specified user, use the no alias-config user form of this command.
The following example accesses the alias configuration mode. It then defines ck as a global alias for the show clock command.
device# configure terminal device(config)# alias-config device(config-alias-config)# alias ck "show clock"
The following example deletes all aliases defined for the user jdoe.
device# configure terminal device(config)# no alias-config user jdoe
