Service Aggregation

Based on the campus design provided and considering an EVPN VXLAN Fabric, the most appropriate layer to be designed as a Border Persona would be the "Services Aggregation" layer. In an EVPN VXLAN architecture, the Border or Border Leaf nodes provide connectivity to external networks, such as WAN, internet, or private connections. They are responsible for routing traffic into and out of the VXLAN fabric and typically also handle services like firewalling, load balancing, and other network services.

Aruba's recommendation for device density in a generic office environment is based on achieving optimal performance and user experience. The suggestion to support 30-50 devices per radio takes into account the typical bandwidth requirements, application usage, and performance expectations in an office setting. This range is designed to ensure that the wireless network can adequately support the number of devices without significant degradation in service quality. It balances the need for connectivity with the practical limits of wireless technology, ensuring that each device maintains a reliable connection and adequate throughput. This recommendation is part of Aruba's best practices for network design and deployment, aimed at providing efficient and effective wireless coverage in office environments.

An RF (Radio Frequency) survey report is crucial for WLAN design as it provides detailed information about the current wireless environment, including signal strengths, interference sources, coverage gaps, and the effectiveness of the existing WLAN infrastructure. For a company like 'No-Stair Inc.' that is planning to refresh its WLAN across a global footprint, understanding the current RF conditions in each location is essential. This information helps in designing a WLAN infrastructure that can meet the specific needs of different areas within the locations, such as the retail area and warehouse, ensuring optimal coverage, performance, and user experience. An RF survey report would allow the designer to make informed decisions regarding the placement of new access points, the selection of appropriate antennas, and the configuration of WLAN parameters to improve coverage and capacity while minimizing interference.

To utilize the UXI Client on Zebra Devices, the necessary licenses include the UXI Cloud Subscription (Option A) and the UXI Agent Subscription (Option B). The UXI Cloud Subscription provides access to the UXI platform's cloud-based analytics and insights, facilitating the monitoring and management of network performance and user experience. The UXI Agent Subscription is required for each Zebra device, enabling it to run the UXI Client software that collects and sends network performance data to the UXI cloud platform. Together, these licenses empower organizations to enhance network visibility and improve the user experience on Zebra devices within their networks.

When presenting a network design solution to a customer, it is crucial to focus on the benefits that the solution will bring to their business. This includes both tangible returns, such as cost savings, increased efficiency, and improved performance, and intangible returns, such as enhanced security, scalability, and user satisfaction. Highlighting how the solution addresses the customer's specific needs and challenges, and how it aligns with their business objectives, helps in demonstrating the value of the solution and facilitates decision-making. Including tangible and intangible returns in the presentation makes it more compelling and relevant to the customer's business goals, thereby increasing the likelihood of the proposal's acceptance.

Comprehensive and Detailed Explanation From Exact Extract:

Key Cabin Requirements:

Each cabin requires a single small form-factor access switch.

Must support 10 GbE uplink toward the distribution switch.

Must provide PoE to power in-room devices or APs.

Must be cost-effective — the CIO does not want wasted ports.

Aruba CX 6100 Series Fit:

The Aruba CX 6100 series is designed for cost-sensitive edge deployments where simplicity and PoE are required.

The 12-port variant (6100 12G Class4 PoE 2SFP+) provides:

Exactly the right number of access ports for cabin needs.

10 GbE uplinks through its SFP+ ports.

Class 4 PoE support for powering access points or IoT devices.

Fanless design options, important for quiet in-room installations.

This ensures no wasted ports, aligning with the CIO’s requirement to minimize unused capacity.

Why not the other options?

A (6200F 12G PoE 2SFP+): The 6200F is higher cost and aimed at larger campus edge deployments with richer feature sets, making it less cost-effective for single-cabin use.

B (6100 24G PoE 4SFP+): Provides 24 access ports, which would be overprovisioned (wasted ports) in cabins where only 1–2 devices need connectivity.

D (6000 12G PoE 2SFP): The 6000 series is more limited in features, and does not support 10 GbE uplinks, which are required by the CIO for increased traffic handling.

Aruba Design Guide Reference:

Aruba ESP Campus Access Design recommends CX 6100 switches for cost-optimized edge/cabin scenarios.

10 GbE uplink requirement and PoE needs align directly with the CX 6100 12-port model with 2x SFP+ uplinks.

This model provides the most cost-effective, right-sized, and standards-compliant option for cabin switches.

Final Justification:

The correct and most cost-effective model for the cabins is the Aruba CX 6100 12G Class4 PoE 2SFP+, which provides PoE, supports 10 GbE uplinks, avoids wasted ports, and matches Aruba best practices for cabin access switches.
