If you’re looking to use command line variables for scripting stuff you have some predefined variables in the NX-OS environment to use and you can also create your own. For now, I’ll just show you how to use the most common, the switches hostname. In some environments you’ll have to save the output of a show tech file and later on upload it via SCP. However, if you’re doing this to 2 or more switches, you’ll need unique file names to make your life easier. Instead of going to each one, you can just use the variable SWITCHNAME in the file. So, if you’re using a script or something like cluster-ssh, this makes your job easier.


sh tech all > bootflash:///shtech-$(SWITCHNAME)
