#NSX #Concept One of the three planes in NSX. The control plane contains different components: ## Centralized Control Plane (CCP) Resides on the [[NSX - Manager.md]]. ### Functions/Responsibilities - MAC Table - Tracks which ESXi host a VM is located on. - ARP - Maps MAC addresses to IP addresses. - ARP traffic can be minimized by answering ARP requests at the host level through NSX's distributed ARP table. - Translates firewall rules into actual IP addresses/rules and pushes them down to ESXi hosts and VMs. ## Local Control Plane (LCP) Resides on ESXi hosts and exchanges state and configuration information from the CCP to the ESXi host. Installed as a VIB through the host prep process.
