The status is Idle, which means that the ring is up and fully connected with the RPL port blocked is not what the specified status means for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Idle is one of the possible statuses for an ERPS ring instance, but it indicates that the ring is not operational and no port is blocked. This can happen when the ring is not configured properly or when there is a miscommunication between the nodes1.

Aruba CX 8325 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 8325 switches are designed for data center spine or core roles, but they can also be used as leaf switches in a VXLAN with EVPN scenario. They support advanced features such as VSX, EVPN, and PFC that enable high performance, scalability, and resiliency for data center networks1.

The wait to restore timer (WTR) Is set in units of minutes; you can set it to prevent frequent topology changes due to a link going up and down is a guideline for configuring timers for Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. The WTR timer is set in units of minutes, and it defines how long a node must wait before restoring traffic on a previously failed link that has recovered1.

ISCSI is a protocol that allows storage devices to communicate over IP networks. ISCSI traffic has different requirements than data traffic, such as low latency, high throughput, and reliability. Therefore, it is not a best practice to send data and storage traffic on the same pair of 10GbE links, as this can cause congestion and performance degradation. It is also not a best practice to use Virtual Routing and Forwarding (VRF) to tunnel ISCSI traffic through the network spine on the same links that data traffic uses. VRF is a technology that creates multiple isolated Layer 3 domains on a physical network, each with its own routing table. VRF does not provide any benefits for ISCSI traffic, as it does not guarantee bandwidth, priority, or quality of service. VRF also adds overhead and complexity to the network configuration1. Therefore, this is not a valid way to support the ISCSI requirements.

In the Asymmetric IRB egress VTEPs bridge the traffic to the destination networks is not a true statement about the IRB type for a spine and leaf network for a single data center that will use multiple leaf switches as Virtual Tunnel End Points (VTEP). Asymmetric IRB is a method of routing traffic between different VXLAN segments using a centralized gateway. In this method, ingress VTEPs route the traffic to the gateway VTEP using a Layer 3 VNI, and egress VTEPs route the traffic to the destination networks using a Layer 2 VNI1.
