ArubaOS is the operating system for all Aruba Mobility Controllers (MCs) and controller-managed wireless access points (APs). ArubaOS 8 delivers unified wired and wireless access, seamless roaming, enterprise grade security, and a highly available network with the required reliability to support high density environments1. Some of the features of ArubaOS 8 are:

Clustered Instant Access Points: This feature allows multiple Instant APs to form a cluster and share configuration and state information. This enables seamless roaming, load balancing, and fast failover for clients2.

Dynamic Radius Proxy: This feature allows an MC to act as a proxy for RADIUS authentication requests from clients or APs. This simplifies the configuration and management of RADIUS servers and reduces the network traffic between MCs and RADIUS servers3.

Wireless controllers: Aruba wireless controllers are devices that centrally manage and control the wireless network. They provide functions such as AP provisioning, configuration, security, policy enforcement, and network optimization.

ArubaOS 10 is the next-generation operating system that works with Aruba Central, a cloud-based network management platform. ArubaOS 10 delivers greater scalability, security, and AI-powered optimization across large campuses, branches, and remote work environments. Some of the features of ArubaOS 10 are:

Scales to more than 10,000 devices: ArubaOS 10 can support up to 10,000 devices per cluster, which is ten times more than ArubaOS 8. This enables customers to scale their networks without compromising performance or reliability.

Unifies wired and wireless management: ArubaOS 10 provides a single platform for managing both wired and wireless devices across the network. Customers can use Aruba Central to configure, monitor, troubleshoot, and update their devices from anywhere.

Both ArubaOS 8 and ArubaOS 10 share some common features, such as:

Unifies wired and wireless management: Both operating systems provide unified wired and wireless access for customers who use Aruba switches and APs. Customers can use a single interface to manage their entire network infrastructure1 .

To troubleshoot an Aruba CX 6300F switch that is failing to boot correctly, you would typically use the USB-C console port. This port allows you to connect to the switch directly with a console cable and access the boot loader menu, where you can see the available OS images and the ServiceOS for recovery and troubleshooting purposes.

Using the provided topology and show command output, it can be determined that L3-SW-2 in the Branch Office does not have a route to reach the subnet where PC1 resides (192.168.1.0/24 in the HQ Office). L3-SW-1 in the HQ Office has a route to the Branch Office subnet (172.16.1.0/24), but without the reciprocal route on L3-SW-2, traffic from the Branch Office will not be able to reach the HQ Office subnet, hence PC1 cannot ping PC2.

This configuration script will achieve the task as it follows the guidelines given by the Senior Engineer. It creates VLAN 20 with name Mgmt, adds L3 SVI on VLAN 20 with IP address 10.1.1.10/24, creates LAG 1 with LACP mode active for the uplink, uses VLAN 20 as the native VLAN on the LAG, and ensures that the interfaces are all ON.References:https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6790/GUID-8F0E7E8B-0F4B-4A3C-AE7F-0F1B5A7F9C5D.html

This script correctly creates VLAN 20 with the name 'Mgmt', adds an L3 SVI for management using the specified IP address, and configures LACP for link aggregation (LAG 1) using the active mode. It also sets VLAN 20 as the native VLAN on the LAG and ensures all interfaces are enabled ('no shut' is the command to bring up the interface if it has been administratively shut down).

The command that is used to set a default route to 10.4.5.1 on an Aruba CX switch when in-band management using an SVI is being used is ip route 0.0 0 0/0 10.4.5.1 . This command specifies the destination network address (0.0 0 0) and prefix length (/0) and the next-hopaddress (10.4.5.1) for reaching any network that is not directly connected to the switch. The default route applies to the default VRF Virtual Routing and Forwarding. VRF is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. VRFs are typically used to segment network traffic for security, privacy, or administrative purposes. , which is used for in-band management traffic that goes through an SVI Switch Virtual Interface. SVI is a virtual interface on a switch that allows the switch to route packets between different VLANs on the same switch or different switches that are connected by a trunk link. An SVI is associated with a VLAN and has an IP address and subnet mask assigned to it12.

The administrative distance is used as a trust rating for route entries (B). It is a metric used by routers to select the best path when there are two or more different routes to the same destination from two different routing protocols. The lower the administrative distance value, the more trustworthy the source of the route. For example, a directly connected network has an administrative distance of 0 because it is the most trusted source of routing information. In contrast, routes learned from different routing protocols have higher administrative distances, reflecting their relative trustworthiness.

In Aruba Central during group creation, users can define various configuration groups to manage settings for multiple devices. A Security group allows you to apply consistent security settings across devices, and a Template group enables you to apply pre-defined configurations to devices. These groups help streamline the deployment and management of network devices in Aruba Central.

A MAC address is divided into two parts: the Organizationally Unique Identifier (OUI) and the Network Interface Controller (NIC) serial number. The OUI is the first three octets of the MAC address and is unique to the manufacturer. The NIC serial number is the last three octets and is unique to the device itself. Therefore, for the MAC address B8-31-B5-80-41-4F, the OUI is B8-31-B5, and the NIC serial number is 80-41-4F.

The route "10.20.0.0/22, vrf default via 10.1.1.1, [110/200]" indicates that it is an OSPF route. This is evidenced by the administrative distance and metric "[110/200]" where 110 is the default administrative distance for OSPF routes.
