The wait is over

Finally, in NX-OS 6.0(2) for Nexus 5000 platform Cisco implemented "default interface" command which lets you return interface to its factory default configuration. It is very-very-very useful feature in the lab environment when one has to do a lot of re-configuration and something does not work as expected simply because of left-over configuration from the previous test. 

This command has been available in IOS since 11.1 and in NX-OS for Nexus 7K since 5.1(1)
