2.1.c Configuration synchronization
This is a feature of vPC. Check out the vPC Chapter of the Nexus 7000 Interfaces Config Guide. It's pretty near the bottom of the page, but it is entitled vPC Configuration Synchronization. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/interfaces/configuration/guide/b-Cisco-Nexus-7000-Ser…
2.1.b Port profiles
Port profiles enable you to configure a number of ports with the same settings (e.g. switchport, switchport mode trunk, switchport trunk allowed vlan 100-110). How to configure with a port profile is in the Interfaces Config Guide in the chapter named Configuring Basic Interface Parameters. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_2/nx-os/interfaces/configuration/guide/if_nxos/if_basic.h… The section on port profiles is after the the section on port-channels, part of the way down. Best just to do a CTRL+F to find "Port Profiles."
This is a feature of Cisco's Dynamic Fabric Automation (DFA) offering. It didn't go anywhere in the market, so I imagine that it won't be long on the exam. (DFA isn't on the CCIE DC v 2.1.) However, there are config guides for DFA as well, and the auto-config chapter is https://www.cisco.com/c/en/us/td/docs/switches/datacenter/dfa/configuration/b-dfa-configuration/b-dfa-configuration_chap…
