Deploy Aruba CX 83xx switches as data center spine switches is a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 83xx switches are designed for data center spine or core roles, and they provide high performance, scalability, and resiliency.  They can support various data center network architectures such as leaf-spine, three-tier, or collapsed core 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 values 1 .

Ring 1, instance 1: control VLAN: 1000protected VLANs: 51-135 Ring l,Instance2: control VLAN: 1001 protected VLANs: 136-220 Ring 2, Instance 1: control VLAN: 1000 protected VLANs: 181 -200 Ring 2, Instance 2: control VLAN: 1003 protected VLANs: 201 -220 is not a valid design for the control and protected VLANs on the VSX fabric 1 switches for an Ethernet Ring Protection Switching (ERPS) solution. The control VLANs must be unique for each ring instance and must not overlap with any protected VLANs. In this design, the control VLAN 1000 is used for both ring 1 instance 1 and ring 2 instance 1, which can cause conflicts and errors.  Also, the protected VLANs 181-220 are used for both ring instances on ring 2, which can cause loops and traffic duplication 2 .

Agents write data to the switch’s current state database is a correct description of how Network Analytics Engine (NAE) agents work. NAE agents are scripts that run on ArubaOS-CX switches and collect data from various sources such as CLI commands, REST APIs, SNMP queries, etc.  The agents write the collected data to the switch’s current state database (CSDB), which stores information about the switch’s configuration, status, and performance 1 .

Enhanced Transmission Selection (ETS) is a network scheduling algorithm that allows the switch to assign different priority and bandwidth values to different traffic classes 1 . This can be useful for transmitting traffic to servers that have different requirements for latency, jitter, or throughput. For example, ETS can prioritize voice or video traffic over data traffic, or allocate more bandwidth to backup or replication traffic.  ETS is configured using the Data Center Bridging Exchange (DCBx) protocol, which advertises the configuration to peer devices 2 . Therefore, implementing ETS on an ArubaOS-CX switch is a valid use case for enabling the switch to assign the correct priority and bandwidth to traffic that it transmits to servers.

Aruba Fabric Composer (AFC) with Nutanix Hypervisor (AHV) integration is possible. AFC is a tool that provides automation and orchestration for managing data center networks composed of ArubaOS-CX switches. AFC can integrate with various data center software such as VMware vSphere, Nutanix AHV, Microsoft Hyper-V, etc.  AFC can discover, monitor, and configure Nutanix AHV clusters and hosts using REST APIs 1 .

Creating a conformance test to check that the firmware matches the desired version is part of the process for using NetEdit to update firmware on ArubaOS-CX switches 1 .  NetEdit is a tool that allows you to manage and monitor multiple switches from a single interface 1 .  It also provides a conformance feature that lets you create tests to verify that the switches comply with your desired configuration and firmware settings 1 .  You can use NetEdit to create a conformance test to check that the firmware matches the desired version and then run it on the switches 1 .

The solution is incorrect because enabling the REST interface in read-only mode is not a minimum requirement for setting up communications between the switch and NetEdit. NetEdit uses the REST interface to configure the switch, so it needs write access as well as read access. Therefore, enabling the REST interface in read-write mode is a minimum requirement for setting up communications between the switch and NetEdit.
