Those who have found their way into some NX-OS environments realize that there are some differences between the Nexus commands and that of IOS based devices. One such difference is how you save the running configuration. NX-OS requires that the administrator type “copy running-config startup-config”. It has been no secret that Cisco has been steering us this direction for a while. All of the current training materials show this as the proper command to save the configuration.
Fortunately, there is a work around for those of us who can’t remember [or choose not] to type anything more than “wr”. This workaround simply involves creating a cli alias as follows.
NX1(config)#cli alias name wr copy running-config startup-config
The alias command has been around for quite some time. It can lend itself useful in those situations where a stubborn engineer like me refuses to change his ways.
