Exploring Command Aliases
You can define command aliases to replace frequently used commands. The command aliases can represent all or part of the command syntax. Command aliases are global and enabled for all user sessions on an NX-OS device and persist across reboots if you save them to the startup configuration. You can define command aliases for commands in any command mode. Command alias translation always takes precedence over any keyword in any configuration mode or submode.
Example 2-14 illustrates command alias configuration and verification.
Example 2-14 Command Alias
! Configuring wr as alias for
copy running-config startup-config
command.
N9K#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
N9K(config)#
cli alias name wr copy running-config startup-config
N9K(config)#
exit
N9K#
show running-config
|
include alias
cli alias name wr copy running-config startup-config
! Using alias
wr
to save running config to starup-config
N9K#
wr
[########################################] 100%
Copy complete, now saving to disk (please wait)…
Copy complete.
N9K#

Exploring Device Hardware and Software
You can use the show version command to determine the software version and device model number, as shown in Example 2-15.
Example 2-15 Show Version Command
! Under the software section of
show version
command, you can see that the software
version of NX-OS installed is 9.3(5) version and under the hardware section of the
output, you can see that the device model is C93180YC-FX.
