A physical interface using Layer 2 mode cannot be attached to a VRF on an ArubaOS-CX switch. A VRF is a virtual routing and forwarding instance that provides logical separation of routing tables on a switch. A physical interface can only be attached to a VRF if it is using Layer 3 mode and has an IP address assigned to it1.

A loopback interface can be attached to a VRF on an ArubaOS-CX switch. A loopback interface is a virtual interface that has an IP address assigned to it and is always up. A loopback interface can be attached to a VRF by using the vrf attach command under its configuration mode1.

Use a firmware update plan to manage both updating the Image on selected devices and reboot is part of the process for using NetEdit to update firmware on ArubaOS-CX switches. NetEdit is a tool that provides automation and analytics for managing ArubaOS-CX switches. A firmware update plan is a type of plan that allows you to update the firmware image on one or more switches and reboot them as needed1.

Instead of using a standard configuration plan to deploy the configuration, create an auto config plan that uses scripts 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. An auto config plan is a type of plan that allows you to use scripts to customize the configuration for each switch based on variables such as serial number, MAC address, or user-defined parameters1.

Attach VNIs 5010 and 5020 to interface 1/1/3 on Switch-2 is not part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VNIs are virtual network identifiers that are used to identify VXLAN segments. A VNI can only be attached to a VLAN interface, not a physical interface, on an ArubaOS-CX switch1.

Work with the server admins to assign a consistent VLAN for VMs 1 and 4. Assign interface 1/1/2 on Switch-1 to the same VLAN is part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VMs 1 and 4 belong to the same VXLAN segment (VNI 5010), so they should be assigned to the same VLAN on their respective hypervisors. Interface 1/1/2 on Switch-1 should also be assigned to the same VLAN as VMs 1 and 4, so that Switch-1 can act as a VTEP for them1.

Extending Layer 2 communications between data centers that connect over Layer 3 MPLS links is not a use case for deploying Ethernet Ring Protection Switching (ERPS). ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. ERPS does not support extending Layer 2 communications over Layer 3 networks such as MPLS1.

Connecting multiple data centers at Layer 2 while minimizing the number of dark fiber connections required is a use case for deploying Ethernet Ring Protection Switching (ERPS). ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. ERPS can be used to connect multiple data centers at Layer 2 using fewer fiber connections than traditional mesh topologies1.

Deploy Aruba CX 6300 switches as data center spine switches is not a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 6300 switches are designed for data center leaf roles, and they provide high density, low latency, and advanced features such as VSX and EVPN. The Aruba CX 83xx switches are more suitable for data center spine roles, and they provide high performance, scalability, and resiliency1.
