Rugged industrial design

The MR66 is designed and tested for salt spray, vibration, extreme thermal conditions, shock and dust and is IP67-rated, making it ideal for extreme environments. Despite its rugged design, MR66 has a low profile and is easy to deploy.

Application-aware traffic shaping

The MR66 includes an integrated layer 7 packet inspection, classification, and control engine, enabling you to set QoS policies based on traffic type. Prioritize your mission critical applications, while setting limits on recreational traffic, e.g. peer-to-peer and video streaming.

Automatic cloud-based RF optimization with spectrum analysis

The MR66’s sophisticated, automated RF optimization means that there is no need for the dedicated hardware or RF expertise typically required to tune a wireless network. An integrated spectrum analyzer monitors the airspace for neighboring WiFi devices as well as non-802.11 interference – microwave ovens, Bluetooth headsets, etc. The Cisco Meraki cloud then automatically optimizes the MR66’s channel selection, transmit power, and client connection settings, providing optimal performance even under challenging RF conditions.

Integrated enterprise security and guest access

The MR66 features integrated, easy-to-configure security technologies to provide secure connectivity for employees and guests alike. Advanced security features such as AES hardware based encryption and WPA2-Enterprise authentication with 802.1X and Active Directory integration provide wire-like security with the convenience of wireless mobility. One-click guest isolation provides secure, Internet-only access for visitors. Our policy firewall (Identity Policy Manager) enables group or device-based, granular access policy control. PCI compliance reports check network settings against PCI requirements to simplify secure retail deployments.

Secure wireless environments using Air Marshal

Cisco Meraki wireless comes equipped with Air Marshal, a built-in wireless intrusion prevention system (WIPS) for threat detection and attack remediation. APs will scan their environment opportunistically or in real-time based on intuitive user-defined preferences. Alarms and auto-containment of malicious rogue APs are configured via flexible remediation policies, ensuring optimal security and performance in even the most challenging wireless environments.

High performance mesh

The MR66’s advanced mesh technologies like multi-channel routing protocols and multiple gateway support enable scalable, high throughput coverage of hard-to-wire areas with zero configuration. Mesh also improves network reliability - in the event of a switch or cable failure, the MR66 will automatically revert to mesh mode, providing continued gateway connectivity to clients.

Self-configuring, self-optimizing, self-healing

When plugged in, the MR66 automatically connects to the Cisco Meraki cloud, downloads its configuration, and joins your network. It self optimizes, determining the ideal channel, transmit power, and client connection parameters. It also self heals, responding automatically to switch failures and other errors.

Low profile, environmentally friendly design

In addition to eliminating excess packaging and documentation, 90% of the access point materials are recyclable. A maximum power draw of only 10.5 watts and a cloud-managed architecture mean that pollution, material utilization and your electric bill are kept to a minimum.

Each device downloads its configuration via Meraki's cloud, applying your network and security policies automatically so you don't have to provision them on-site.

Meraki Cloud Management Architecture

High Performance RF Design

Every Meraki access point continuously and automatically monitors its surroundings to maximize WiFi performance. By measuring channel utilization, signal strength, throughput, signals from non-Meraki APs, and non-WiFi interference, Meraki APs automatically optimize WiFi performance of individual APs and maximize system-wide performance.

Meraki APs have been deployed and proven in the most demanding environments, supporting more than 100 users per AP and collectively serving hundreds of Megabits per second of user traffic to thousands of devices. By eliminating traditional hardware controllers, Meraki also eliminates the performance bottleneck that often chokes high-density wireless deployments.

By measuring utilization from neighboring APs, detecting WiFi signals from non-Meraki APs, and identifying non-WiFi interference, Meraki APs continuously stay on top of changing and challenging conditions. Tools such as real-time spectrum analysis and live channel utilization deliver immediate information on the RF environment at any part of the network. Even in dynamic environments, Meraki networks automatically detect and adapt to interference from non-WiFi sources.

Real-time and historical metrics ensure maximum system-wide performance. Wireless channels, AP output power, and client connection settings are automatically adapted to changing performance and interference conditions, eliminating the need for tedious manual adjustment of dozens of independent parameters.

Mesh networking, included in every Meraki AP, extends coverage to hard to wire areas and creates a self-healing network that is resilient to cable and switch failures, continuing to operate despite failures or configuration changes in the rest of the network, without the need for manual configuration or optimization.

Enterprise Security and a Dedicated Radio

The MR series comes equipped with complete out-of-the-box enterprise class security. Segment wireless users, applications, and devices; secure your network from attacks and enforce the right policies for each class of users. A built-in stateful policy firewall, 802.1X/RADIUS support, and native Active Directory integration deliver fine-grained access control, while a guest access firewall provides secure, Internetonly guest WiFi in just one click. Integrated network access control (NAC) provides end-user anti-virus scanning for accurate client device posture asessment to protect your wired and wireless network against virus infections.

Indoor APs feature a radio dedicated to full-time scanning, rogue AP containment, and automatic RF optimization. With Air Marshal, it is possible to set up a real-time wireless intrusion detection and prevention system (WIDS/WIPS) with user-defined threat remediation policies and intrusion alarms, enabling secure wireless environments without complex setup or systems integration. Auto RF eliminates the need for manual RF configuration by scanning the environment for utilization, interference, and other metrics, and computing the optimal channel and power settings for every AP in the network. Meraki WLANs are fully HIPAA and PCI compliant.

Cisco Meraki networks deploy quickly and easily, without training or dedicated staff. Moreover, Cisco Meraki provides a rich feature set that provides complete control over devices, users, and applications, allowing for flexible access policies and rich security without added cost or complexity.

Cisco Meraki's cloud management provides the features, security, and scalability for networks of any size. Cisco Meraki scales from small sites to campuses, and even distributed networks with thousands of sites. Cisco Meraki devices, which self-provision via the cloud, can be deployed in branches without IT. Firmware and security signature updates are delivered seamlessly, over the web. With the cloud, branches can automatically establish secure VPN tunnels between one another with a single click.

With a secure, PCI and HIPAA compliant architecture and fault tolerant design that preserves local network functionality during WAN outages, Cisco Meraki is field proven in high security and mission critical network applications.

Cloud Management Architecture

Cisco Meraki's architecture provides feature rich network management without on-site management appliances or WiFi controllers.

Every Cisco Meraki device - including wirelesss access points, Ethernet switches, and security appliances - connects over the Internet to Cisco Meraki's datacenters, which run Cisco Meraki's cloud management platform. These connections, secured via SSL, utilize a patented protocol that provides real time visibility and control, yet uses minimal bandwidth overhead (typically 1 kbps or less.)

In place of traditional command-line based network configuration, Cisco Meraki provides a rich web based dashboard, providing visibility and control over up to tens of thousands of Cisco Meraki devices, anywhere in the world. Tools, designed to scale to large and distributed networks, make policy changes, firmware updates, deploying new branches, etc. simple and expedient, regardless of size or location. Cisco Meraki's real time protocols combine the immediacy of on-premise management applications with the simplicity and centralized control of a cloud application.

Every Cisco Meraki device is engineered for cloud management. Specifically, this means that Cisco Meraki devices are designed with memory and CPU resources to perform packet processing, QoS, layer 3-7 security, encryption, etc. at the network edge. As a result, no network traffic passes through the cloud, with the cloud providing management functionality out of the data path. This architecture enables networks to scale horizontally, adding capacity simply by adding more endpoints, without concern for centralized bottlenecks or chokepoints. Equally important, since all packet processing is performed on premise, end-user functionality is not compromised if the network's connection to the cloud is interrupted.

Cisco Meraki's cloud platform is designed to spread computation and storage across independent server clusters in geographically isolated datacenters. Any server or datacenter can fail without affecting customers or the rest of the system. Additionally, Cisco Meraki's datacenter design is field proven to support tens of thousands of endpoints.

Cloud Management Architecture

Powerful Insight and Troubleshooting Tools

Cisco Meraki's cloud architecture delivers powerful insight and includes live tools integrated directly into the dashboard, giving instant analysis of performance, connectivity, and more. Using live tools, network administrators no longer need to go on site to perform routine troubleshooting tests. Visibility into devices, users, and applications gives administrators the information needed to enforce security policies and enable the performance needed in today's demanding network environments.

Troubleshooting tools such as ping, traceroute, throughput, and even live packet captures are integrated directly into the Cisco Meraki dashboard, dramatically reducing resolution times and enabling troubleshooting at remote locations without on-site IT staff.

Layer 7 application visibility

Out-of-Band Control Plane

Cisco Meraki's out-of-band control plane separates network management data from user data. Management data (e.g., configuration, statistics, monitoring, etc.) flows from Cisco Meraki devices (wireless access points, switches, and security appliances) to Cisco Meraki's cloud over a secure Internet connection. User data (web browsing, internal applications, etc.) does not flow through the cloud, instead flowing directly to its destination on the LAN or across the WAN.

Advantages of an out of band control plane:

Scalability

• Unlimited throughput: no centralized controller bottlenecks
• Add devices or sites without MPLS tunnels
• Add switching capacity without stacking limitations

Reliability

• Redundant cloud service provides high availability
• Network functions even if management traffic is interrupted

Security

• No user traffic passes through Cisco Meraki's datacenters
• Fully HIPAA / PCI compliant

What happens if a network loses connectivity to the Cisco Meraki cloud?
Because of Cisco Meraki's out of band architecture, most end users are not affected if Cisco Meraki wireless APs, switches, or security appliances cannot communicate with Cisco Meraki's cloud services (e.g., because of a temporary WAN failure):

• Users can access the local network (printers, file shares, etc.)
• If WAN connectivity is available, users can access the Internet
• Network policies (firewall rules, QoS, etc.) continue to be enforced
• Users can authenticate via 802.1X/RADIUS and can roam wirelessly between access points
• Users can initiate and renew DHCP leases
• Established VPN tunnels continue to operate
• Local configuration tools are available (e.g., device IP configuration)

While Cisco Meraki's cloud is unreachable, management, monitoring, and hosted services are temporarily unavailable:

• Configuration and diagnostic tools are unavailable
• Usage statistics are stored locally until the connection to the cloud is re-established, at which time they are pushed to the cloud
• Splash pages and related functionality are unavailable

Cisco Meraki Datacenter Design

Cisco Meraki's cloud management service is colocated in tier-1, SAS70 type II certified datacenters. These datacenters feature state of the art physical and cyber security and highly reliable designs. All Cisco Meraki services are replicated across multiple independent datacenters, so that customer-facing services fail over rapidly in the event of a catastrophic datacenter failure.

Security Tools for Administrators

In addition to Cisco Meraki's secure out-of-band architecture and hardened datacenters, Cisco Meraki provides a number of tools for administrators to maximize the security of their network deployments. These tools provide optimal protection, visibility, and control over your Cisco Meraki network.

Two-factor authentication
Two-factor authentication adds an extra layer of security to an organization's network by requiring access to an administrator's phone, in addition to her username and password, in order to log in to Cisco Meraki's cloud services. Cisco Meraki's two factor authentication implementation uses secure, convenient, and cost effective SMS technology: after entering their username and password, an administrator is sent an a one-time passcode via SMS, which they must enter before authentication is complete. In the event that a hacker guesses or learns an administrator's password, she still will not be able to access the organization's account, as the hacker does not have the administrator's phone. Cisco Meraki includes two-factor authentication for all enterprise users at no additional cost.

Password policies
Organization-wide security policies for Cisco Meraki accounts help protect access to the Cisco Meraki dashboard. These tools allow administrators to:

• Force periodic password changes (e.g., every 90 days)
• Require minimum password length and complexity
• Lock users out after repeated failed login attempts
• Disallow password reuse
• Restrict logins by IP address

Role-based administration
Role-based administration lets supervisors appoint administrators for specific subsets of an organization, and specify whether they have read-only access to reports and troubleshooting tools, administer managed guest access, or can make configuration changes to the network. This minimizes the chance of accidental or malicious misconfiguration, and restricts errors to isolated parts of the network.

Configuration change alerts
The Cisco Meraki system can automatically send human-readable email and text message alerts when configuration changes are made, enabling the entire IT organization to stay abreast of new policies. Change alerts are particularly important with large or distributed IT organizations.

Configuration and login audits
Cisco Meraki logs the time, IP, and approximate location (city, state) of logged in administrators. A searchable configuration change log indicates what configuration changes were made, who they were made by, and which part of the organization the change occurred in.

SSL certificates
Cisco Meraki accounts can only be accessed via https, ensuring that all communication between an administrator's browser and Cisco Meraki's cloud services is encrypted.

Idle Timeout
30 seconds before being logged out, users are shown a notice that allows them to extend their session. Once time expires, users are asked to log in again.
