Aruba CX 6300 switches are an appropriate choice for leaf switches in a leaf-spine topology that uses Virtual Extensible LAN (VXLAN) with Ethernet VPN (EVPN) is a correct positioning of ArubaOS-CX switches in the data center. The Aruba CX 6300 switches are designed for data center leaf roles, and they support advanced features such as VSX, EVPN, and PFC that enable high performance, scalability, and resiliency for data center networks.

VSX is not recommended for the access layer of data centers and campuses while VSF is recommended for the core. VSX and VSF are both high availability solutions that provide redundancy and load balancing across a pair of switches1. However, VSX is recommended for the core and aggregation layers of data centers and campuses, while VSF is recommended for the access layer of campuses1. The statement is false because it reverses the recommended roles of VSX and VSF.

Inside a configuration plan, right-click any device-specific parameters and modify the parameter per-device is what you should do if you want to use NetEdit to manage ArubaOS-CX switches and deploy a standard config to the switches, but need the config to include a few device-specific settings such as hostname and IP address. This approach allows you to edit any parameter value for individual devices within a configuration plan without affecting other devices or creating separate plans.
