It enables the switch REST API interface, if disabled is not something that NetEdit 2.0 does after it discovers a switch. NetEdit 2.0 is a tool that provides configuration management and validation for ArubaOS-CX and ArubaOS-Switch devices. NetEdit 2.0 can discover switches using various methods such as IP range scan, LLDP scan, CSV import, etc. However, NetEdit 2.0 cannot discover or communicate with switches that have their REST API interface disabled because NetEdit 2.0 relies on REST API calls to interact with switches1.

A Layer 3 VLAN interface is an interface that can be assigned an IP address and attached to a VRF. A VRF allows multiple instances of a routing table to co-exist within the same router. By attaching a Layer 3 VLAN interface to a VRF, you can isolate the traffic of that VLAN from other VLANs and routing domains12. This can enhance security and performance of the network.

Both ARP-Suppression and ND-Suppression are disabled by default is not a true statement about ARP and ND Suppression. ARP-Suppression is enabled by default on ArubaOS-CX switches, while ND-Suppression is disabled by default1. ARP-Suppression and ND-Suppression are features that reduce broadcast traffic on VXLAN networks by using a local ARP/ND cache on each switch instead of flooding ARP/ND requests to all VXLAN tunnel endpoints (VTEPs)1.

To ensure a minimum bandwidth guarantee between two endpoints traffic with various 802.1p values is a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch. ETS is a feature that provides bandwidth allocation and priority assignment for different traffic classes based on IEEE 802.1Qaz standard. ETS can help to ensure a minimum bandwidth guarantee between two endpoints by assigning different priority groups and bandwidth percentages to different traffic classes based on their 802.1p values1.

The IPv6 and IPv4 overlay networks can be encapsulated with VXLAN and transmitted through the underlay network is a true statement about EVPN and IPv6 for configuring an EVPN solution for a dual-stack IPv4 and IPv6 protocol in the overlay networks. VXLAN is a feature that provides Layer 2 extension over Layer 3 networks using UDP encapsulation. VXLAN can support both IPv4 and IPv6 overlay networks over an IPv4 or IPv6 underlay network2.
