RF and Roaming Optimization for Aruba 802.11ac Networks
This Solution guide covers design recommendations and best practices to achieve best RF performance and seamless roaming on Aruba 802.11ac Networks. This solution guide is best applicable for office and university campus/dorms environments. It mainly covers four areas: 1) AP Placement, 2) RF Consideration, 3) Roaming Optimization, 4) Device Specific Recommendations.
This solution guide is designed for Aruba Mobility controllers running ArubaOS 6.3.x and later. It assumes that reader has a working knowledge of Aruba WLAN architecture and has already deployed it in an enterprise or campus environment.

This might be a n00b problem, but I can't edit the rf arm-profiles. Im running code 188.8.131.52. I go to config t
and type rf then hit space which immediatly changes the command to rft, which is apparently an RF Troubleshooting test. When I ? at the config prompt I don't see anything for rf. All the documentation I've seen says to edit these settings you should be in config mode, then simply type rf arm-profile and the name which will allow you to edit the ARM settings. Ultimately I'm trying to change the default arm-profile setting for Client Match Band Steer G Band Max Signal (-dBm). The default is 45, Im trying to set it to 10 per the document above.
Thank you in advance.

Ashu, does the CSR suggested in this document need to be lowered? It's currently 15 for 11ac APs, but as I understand it, setting the value this high is no longer suggested?
Thanks, Mike! You can always reach out to us if you need any help with your Lync Deployment needs.

I thought I was waiting on approval to get the document in PDF format, but it appears as though my spam filter was just blocking the email with the link to download the VRD. I have the PDF now so I'm happy!
I had the privilege of working with Ashu in the past on a Lync deployment and he provided us the tweaks found in this VRD before it existed. It's great to finally see this information in a VRD with a lot of explanation for all customers to benefit from. Great work, guys!

Hi there--so glad this doc is helpful to you! We love getting feedback from our customers.
We are working on a solution that would allow you to directly download these docs as PDFs--in the meantime we hope there is not much of a delay for you to access the information as a PDF.
Thank you again,

Thanks for your writing, very useful. I have a question on Mcast. On page 9 you recomend to enable both MCAST Rate Optimization and DMO, but also rise DMO threshold to 80. How can be preferable to use 80 TXOPs instead of broadcasting the MCAST frame at the optimized rate? Could you please point me to any reading to understand? Thanks!!!
[EDITED] An Aruba engineer kindly helped with this basic question. Mcast frames do not use MCS datarates and contains a single packet per PDU. DMO uses MCS datarates and many packets can be aggregated.
This VRD covers the deployment of Aruba WLAN in a typical campus network, and it is considered part of the Base Designs within the VRD core technologies series. This guide covers the design recommendations for a campus deployment and it explains the various configurations needed to implement the Aruba secure, highperformance, multimedia grade WLAN solution in large campuses.
Aruba WLAN has a logical four-tier operating model that consists of these four layers:
Management - The management layer consists of AirWave®. AirWave provides a single point of management for the WLAN, including reporting, heat maps, centralized configuration, and troubleshooting.
Network services - The network services layer consists of master mobility controllers and Amigopod. Amigopod provides secure and flexible visitor management services. The master controllers provide a control plane for the Aruba WLAN that spans the physical geography of the wired network. The control plane does not directly deal with user traffic or access points (APs). Instead the control plane provides services such as whitelist coordination, valid AP lists, Control Plane Security (CPSec) certificates, Radio Frequency Protect (RFProtect™) coordination, and Remote Authentication Dial-In User Service (RADIUS) or authentication, authorization, and accounting (AAA) proxy.
Aggregation - The aggregation layer is the interconnect point where the AP, air monitor (AM), and spectrum monitor (SM) traffic aggregates. This layer provides a logical point for enforcement of roles and policies on centralized traffic that enters or exits the enterprise LAN.
Network access - The network access layer is comprised of APs, AMs, and SMs that work together with the aggregation layer controllers to overlay the Aruba WLAN.

A great VRD that covers the deployment of Aruba WLAN in a typical campus network.
I have 2 comments regarding ''Type of Wired Access Switches":
- For 802.3af switches when using AP33x, both 5Ghz and 2.4Ghz will operate 1x1:1 mode not only 2.4Ghz radio.
- Why IPM (Intelligent Power Monitoring/Management) is not considered as part of the design? it will help using AP33x with no restrictions when plugged to a 802.3af switch.
This guide covers the deployment of Aruba remote access points (RAP) in fixed telecommuter and micro branch office sites, and it is considered part of the base designs guides within the VRD core technologies series. This guide covers the design recommendations for remote network deployment and it explains the various configurations needed to implement a secure, high-performance virtual branch office (VBN) solution with Aruba RAPs.
This Solution Guide describes best practices for implementing an Aruba 802.11 wireless network that supports thousands of highly mobile devices (HMDs) such as Wi-Fi phones, handheld scanning terminals, voice badges, and computers mounted to vehicles. It describes the design principles particular to keeping devices that are in constant motion connected to the network as well as best practices for configuring Aruba Networks controllers and the mobile devices. The comprehensive guide addresses six areas of network planning to ensure a high quality of service for roaming data and voice sessions: device configuration, airtime optimization, roaming optimization, IP mobility configuration, IP multicast configuration, and interference resistance. A detailed troubleshooting section covers common issues that arise with these types of WLANs.
This guide explains how to implement an Aruba 802.11n wireless network that must provide high-speed access to an auditorium-style room with 500 or more seats. Aruba Networks refers to such networks as high-density wireless LANs (HD WLANs). Lecture halls, hotel ballrooms, and convention centers are common examples of spaces with this requirement. Because the number of concurrent users on an AP is limited, to serve such a large number of devices requires access point (AP) densities well in excess of the usual AP per 2,500 – 5,000 ft2 (225 – 450 m2). Such coverage areas therefore have many special technical design challenges. This validated reference design provides the design principles, capacity planning methods, and physical installation knowledge needed to successfully deploy HD WLANs.
ArubaOS is the operating system, software suite, and application engine that operates Aruba mobility controllers and centralizes control over the entire mobile environment. The ArubaOS wizards, command-line interface (CLI), and the ArubaOS Web UI are the primary means used to configure and deploy ArubaOS. For a complete description of ArubaOS, refer to the ArubaOS User Guide for your release.
