The ISL and keepalive goes down, and after a few seconds, the keepalive link restores. Switch-1 and Switch-2 remains up. The Split-recovery mode is enabled. In this case the secondary switch shutdowns SVIs when keepalive is restored is a correct description of how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The ISL is the inter-switch link that connects two VSX nodes and carries data traffic. The keepalive link is a separate link that carries control traffic between two VSX nodes. The split-recovery mode is a feature that prevents split-brain scenarios when both VSX nodes lose connectivity with each other but remain up. When the ISL and keepalive goes down, both VSX nodes continue to forward traffic independently. When the keepalive link restores, the secondary switch detects that it has lost synchronization with the primary switch and shuts down its SVIs to prevent traffic loops1.

VSX permits admins to select which features to synchronize between members while VSF requires manual configuration of identical features on each member of the VSF fabric is a way that Virtual Switching Extension (VSX) differs from Virtual Switching Framework (VSF). VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSF is a feature that provides active-standby forwarding and redundancy for legacy campus switches. VSX allows admins to select which features to synchronize between members using an opt-in model, while VSF requires manual configuration of identical features on each member using a commander-member model1.

A broadcast arrives in VLAN 10 on Switch-1. Switch 1 forwards the frame on all interfaces assigned to VLAN10, except the incoming interface. It replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to 192.168.1.2 and 192.168.1.3 is a correct explanation of how the switch handles the traffic. Switch-1, Switch-2, and Switch-3 are ArubaOS-CX switches that use VXLAN and EVPN to provide Layer 2 extension over Layer 3 networks. VXLAN is a feature that uses UDP encapsulation to tunnel Layer 2 frames over Layer 3 networks using VNIs. EVPN is a feature that uses BGP to advertise multicast information for VXLAN networks using IMET routes. Switch-1 receives a broadcast in VLAN 10, which belongs to VNI 5010. Switch-1 forwards the frame on all interfaces assigned to VLAN 10, except the incoming interface, as per normal Layer 2 switching behavior. Switch-1 replicates the broadcast, encapsulates each broadcast with VXLAN, and sends the VXLAN traffic to both 192.168.1.2 and 192.168.1.3, which are Switch-3’s and Switch-2’s loopback interfaces respectively.

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.

It collects information about the switch hardware is 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. After NetEdit 2.0 discovers a switch, it collects information about the switch hardware such as model number, serial number, MAC address, firmware version, etc1.

Split-recovery mode is a feature of ArubaOS-CX that prevents traffic loss when the ISL goes out-of-sync and keepalive subsequently fails12. This can happen if the ISL is restored after a failure but the VSX nodes are not synchronized. Split-recovery mode enables the secondary switch to restore its VSX LAGs after 10 keepalive packets are missed, approximately 10 seconds after keepalive goes down2. This avoids a split brain situation where both switches act as primary and forward traffic independently, causing loops and duplicate packets1. Therefore, disabling split-recovery mode is not a use case for preventing split brain situations, and the correct answer is yes. For more information on split-recovery mode and VSX, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet3 and the Virtual Switching Extension (VSX) Guide for your switch model2.

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.

Omit the device-specific settings from the configuration plan and include them in command scripts instead is not 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 would require you to create separate command scripts for each switch, which can be tedious and error-prone. A better approach would be to use an auto config plan that uses scripts to customize the configuration for each switch based on variables such as serial number, MAC address, or user-defined parameters1.
