QoS Configuration Guide | Meraki MX64 | Introduction

Introduction

The Meraki MX64 Security Appliance is ideal for organizations

considering a Unified Threat Management (UTM) solution, for

distributed sites, campuses or datacenter VPN concentration.

Since the MX64 is 100% cloud managed, installation and remote

management is simple. The MX64 has a comprehensive suite of

network services, eliminating the need for multiple appliances.

These services include SD-WAN capabilities, application-based

firewalling, content filtering, web search filtering, SNORT® based

intrusion detection and prevention, Cisco Advanced Malware

Protection (AMP), web caching, 4G cellular failover and more. Auto

VPN and SD-WAN features are available on our hardware and

virtual appliances, configurable in Amazon Web Services.

Note:

The firewalls recommended here are quality hardware that we

have tested internally and work reliably with our services.

However, given the constantly updated firmware and physical

changes made by manufacturers and the nature of cloud-based

services, RingCentral cannot control the final configuration of

the hardware or your computer systems/networks, or promise

that any given firewall will work with your system, or guarantee

that our information is 100% up to date.

This document is intended to be used as a guide to assist in

customer network configuration.

These settings have been tested within the RingCentral Tier 3

Lab, and have been proven to increase the QoS per lab

requirements.

4. Go Back into Security Appliance and select Traffic Shaping. (Figure 3)

Figure 3

QoS Configuration Guide | Meraki MX64 | Configure Your Firewall

5. Set the Uplink configuration for the bandwidth which your circuit is providing for each WAN link. (Example circuit 5 Mbps and no WAN 2 or

Cellular.) (Figure 4)

Figure 4

If utilizing WAN2 and Cellular assure the devices are utilizing only one Network on one subnet and you are not load balancing or

traversing between Wired and/or Cellular Networks.

7. Set a Traffic shaping rule: (Figure 6)

a) Rule #1.

i. Set bandwidth management (BWM) for the RingCentral Supernets.

ii. Bandwidth limit set to “Ignore network per-client (unlimited).

iii. Priority set to “High”.

iv. DSP tagging set to “46 (EF - Expedited Forwarding, Voice).

6. Under Global bandwidth limits set your per-client limit. (With our 5 Mbps circuit we are allowing 2 Mbps per client with a burst if needed.)

Quality of Service

RingCentral provides reliable, high-quality voice service. Your local

network, internet connection, and your router all contribute to overall call

quality, with sufficient dedicated bandwidth to voice calls being the biggest

factor. To help you manage your call quality, RingCentral offers tools to

check your internet connection speed, and instructions to configure the

Quality of Service (QoS) settings of your routers.

The QoS settings on your router enable it to give priority to real-time voice

traffic over lower-priority data traffic, such as large downloads. This

document provides recommended configuration settings to ensure the

highest-possible QoS experience on the Meraki MX64 Firewall/Router.

Please reference the relevant TCP/UDP settings on the Ports and Firewalls

table to complete the recommended setup.

Supported Browsers for Test

Internet Explorer®11 or higher (Windows®XP, 7, 8 or higher)

Firefox®version 36 or higher (Windows and Mac®)

Safari version 6.2 or higher (Mac)

Note:

The routers recommended here are quality hardware that we

have tested internally and work reliably with our services.

However, given the constantly updated firmware and physical

changes made by manufacturers and the nature of cloud-based

services, RingCentral cannot control the final configuration of

the hardware or your computer systems/networks, or promise

that any given router will work with your system, or guarantee

that our information is 100% up to date.

Test Your Connection Capacity

The RingCentral Connection Capacity test will help determine the maximum

number of simultaneous RingCentral calls that can be supported on your

broadband connection. Run this test during normal business hours when the

connection is in use by other applications, including large file downloads.

The capacity test should be run using the maximum number of simultaneous

call connections needed, and should use the G.711 codec selection.

Specific requirements for QoS:

Bandwidth—100 Kbps up and down per call

Latency (one-way)—less than 150 ms

Jitter—not to exceed 100 ms

Packet loss—less than 3%

These requirements are the foundation for ensuring your local network can

support satisfactory VoIP. Failure to meet these requirements will result in

poor voice quality.

When the test completes, you will see the recommended number of

simultaneous calls your connection can support while maintaining good quality

voice calls.

QoS Configuration Guide | Meraki MX64 | Quality of Service

Test Your Connection Quality

RingCentral provides a VoIP Quality test that will simulate VoIP calls

between your computer and RingCentral, and provide an estimate of

the voice quality you should expect when using our service. For the

most accurate results, run this test at least three different times

throughout a business day, and during peak usage times, while

connected to the network that you plan to use for RingCentral.

A two-minute test is typically sufficient, while longer tests are useful

to find intermittent problems or to simultaneously test VoIP

performance along with other traffic, such as file transfers or remote

access.

Select the maximum number of simultaneous users you expect to

support, and set the test duration between 1 and 5 minutes; 2

minutes is considered sufficient in most instances.

Click jitter and packet loss on the RESULTS SUMMARY panel to view

the overall quality of your expected VoIP connection.

MOS score (Mean Opinion Score) refers to a test that has been used

for decades in telephony networks to obtain the human user's view of

the quality of the network. The MOS is the arithmetic mean of all the

individual scores, and can range from 1 (worst) to 5 (best). A MOS

score of 4 is good.
