The first thing I tell junior engineers when they work on Nexus is this: if what you're doing doesn't work, check for an unloaded feature. This nails everyone (myself included) at least a few times before it sinks in. No more speed-related interface names Every Ethernet interface is named Ethernet in NX-OS. No more FastEthernet, GigabitEthernet, or T
