The alias also has its help information that is displayed after * in the following format:
*command-alias=original-command
For example, in the privileged EXEC mode, the default alias s stands for show. You can enter s? to
query the key words beginning with s and the help information of the alias.
Ruijie#s?
*s=show show start-chat start-terminal-service
If an alias represents more than one word, the command will be displayed in brackets. For example, if
you set sv stand for show version in the privileged EXEC mode, then:
Ruijie#s?
*s=show *sv="show version" show start-chat
start-terminal-service
The alias must begin with the first letter of the command. The first letter of the command cannot be a
space. The space before the command cannot be used as a valid alias.
Ruijie# s?
show start-chat start-terminal-service
The command alias also has its help information. For example, if the alias ia represents ip address in
the interface configuration mode, then:
Ruijie(config-if)#ia ?
A.B.C.D IP address
dhcp IP Address via DHCP
Ruijie(config-if)# ip address
The above help information lists the parameters of ip address and shows the actual command name.
You must enter an entire alias; otherwise it cannot be recognized.
Use the show aliases command to show the aliases setting in the system.
The following example uses def-route to represent the default route setting of ip route 0.0.0.0 0.0.0.0
192.168.1.1 in the global configuration mode:
Ruijie# configure terminal
Ruijie(config)# alias config def-route ip route 0.0.0.0 0.0.0.0 192.168.1.1
Ruijie(config)#def-route?
*def-route="ip route 0.0.0.0 0.0.0.0 192.168.1.1"
Ruijie(config)# end
Ruijie# show aliases config
globle configure mode alias:
def-route ip route 0.0.0.0 0.0.0.0
192.168.1.1
