During my studying of all things CISCO there was a little gem of a command-set that I am going to share this is the push and pop commands cisco link.
What are they what do they do I hear you cry well have you ever been 7 layers deep in cisco configuration and need to reconfigured a subnet on an interface quickly or un-shut that interface and don’t want to lose where you currently are in the CLI
NX-1(config-if)#ip address x.x.x.x/yy
as you can see that after the push command we are able to complete other configuration and they type pop to return to where we were nice little time saver.
Cisco calls it Saving and Restoring a Command Mode here is the link https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_1/nx-os/fundamentals/configuration/guide/b_Cisco_Nexus_7000_Series_NX-OS_Fundamentals_Configuration_Guide__Release_4-1/Cisco_Nexus_7000_Series_NX-OS_Fundamentals_Configuration_Guide__Release_4-1_chapter4.html
