MS390-48U Highlights

Meraki MS390 Series Switch

The Meraki MS390 is the most powerful access switch in the Meraki portfolio which combines the simplicity of cloud-managed IT with the power of innovative Cisco switching technology. The Meraki MS390 addresses the most demanding enterprise applications by combining the simplicity of the Meraki dashboard with powerful switching hardware. To satisfy high-bandwidth applications and the deployment of high-speed 802.11ax/wifi-6 access points, the MS390 provides multigigabit ports, 480G stacking, and modular 10/40G uplinks. The MS390 delivers resiliency with fast stack convergence and StackPower. The MS390 provides Adaptive Policy using an overthe-wire tag which segments traffic into security groups to deliver scalable security. The MS390 is integrated under the Meraki dashboard to provide a simply powerful solution to the most demanding wired access applications.

Adaptive Policy provides simple & scalable security policies to segment traffic using Security Groups. Security Groups are created in the dashboard using natural language such as “IOT device” & “Guest.” The security policy intent (e.g., Permit or Deny) is then simply provisioned between Security Groups which results in the segmentation of each group’s traffic. By making security policy management intuitive and scalable relative to legacy IP-address based Access Control Lists, Adaptive Policy empowers operators to confidently secure their network traffic independent of future network changes.

By pooling & distributing power across MS390s using a series of StackPower cables, StackPower provides simple and resilient power distribution across the stack.

Simple & Powerful

Meraki access and aggregation layer switches power networks of every size. They combine secure, scalable, robust performance with an intuitive management experience that requires no additional training.

Deploy, Manage, and Troubleshoot in minutes

Meraki switches offer zero-touch provisioning and can be configured entirely from a web browser. Pioneering network topology and remote packet capture features simplify troubleshooting, especially on remote locations.

Build High-Performance, Resilient Networks

Meraki switches provide the essentials for building high-performance networks that can help maintain seamless network service. Multigigabit Ethernet squeezes more speed out of existing cabling. Switches can be physically stacked via dedicated lightning-fast cabling and cross-stack link aggregation used to create a resilient connection to the network core using all available bandwidth. Further strengthen the network with IP gateway redundancy or powerful dynamic routing using OSPF.

MS Cloud Managed Switches Solutions:

MS Cloud Managed Switches

The Cisco Meraki MS is the world's first cloud-managed switch, bringing the benefits of the cloud to enterprise networks: simplified management, reduced complexity, network wide visibility and control, and lower cost for branch and campus deployments.

Cisco Meraki access switching is available in two product lines — the MS220 and MS320 families. Mission-critical features — like deep, Layer 7 application visibility, virtual stacking, QoS for business critical applications, 802.1X access control, and more — are present in both families.

The MS320 is the flagship Cisco Meraki layer 3 access switch, designed for high-speed connectivity and high availability, with optional redundant power supplies. In addition, the MS320's full-PoE models are ideal for next generation 802.11ac wireless AP, including the Cisco Meraki MR34 — with plenty of budget to spare for other PoE clients.

The MS220 family provide layer 2 access switching, is ideal for deploying to branch locations, and supports an optional, rack-mountable remote PSU.

Simplified Management and Operations

Cisco Meraki's cloud managed architecture makes it simpler than ever to quickly provision and reconfigure switch ports with security, QoS, and other parameters. The Cisco Meraki dashboard provides unified policies, event logs, and monitoring, which make it easy to manage and grow large network deployments.

By providing a complete, powerful set of management functions over the web, Cisco Meraki's cloud-based management eliminates the need for proprietary command line configuration interfaces which require expensive and time consuming certifications. Cisco Meraki MS switches can be fully deployed and provisioned in minutes, without requiring any local configuration or staging. Additional or replacement switches can be sent to remote offices and installed by non-technical staff, saving thousands of dollars in time and travel expenses.

The Cisco Meraki MS family also includes several remote diagnostic features, from network connectivity and cable integrity tests to latency measurement tools. For deep client troubleshooting, administrators can even perform per-port remote pcap packet captures without any additional probes or hardware on site.

Layer 7 Visibility
Cisco Meraki is the only switch to include integrated Layer 7 fingerprinting. Identify hundreds of applications from business apps to BitTorrent and YouTube. User fingerprinting with Google-like search allows administrators to easily identify and control individual users, PCs, iMacs, iPads, Androids, and other devices. This unprecedented visibility allows you to optimize network resources and maintain optimal network performance.

Converged Voice, Video and Data Environments
The Cisco Meraki switch family is designed to unify data, voice, and video onto a single IP backbone. All Cisco Meraki switches support rich quality- of-service (QoS) functionality for prioritizing data, voice, and video traffic. The switches support eight class-of-service (CoS) queues on every port, enabling them to maintain end-to-end traffic prioritization.

PoE models provide 15.4 watts of power per port for VoIP telephones, IP security cameras, wireless access points (APs), and other IP devices. The Cisco Meraki MS switches also support standards-based 25.5 watt (30 watt max per port) IEEE 802.3at for powering networked devices like multiple radio IEEE 802.11n APs and video phones that may require more power than available with IEEE 802.3af. In addition, using LLDP, PoE power is intelligently budgeted to maximize the number of PoE clients supported.

To ease deployment, Cisco Meraki switches support the industry- standard Link Layer Discovery Protocol (LLDP), enabling switches to automatically discover Ethernet-enabled devices, determine their power requirements and join the correct virtual LAN (VLAN).

Cisco Meraki's Unified Software Architecture
Cisco Meraki switches run the same Cisco Meraki operating system used by Cisco Meraki's firewalls and wireless LAN products. The use of a common operating system allows Cisco Meraki to deliver a consistent experience across all product lines

Layer 3
Cisco Meraki MS320 series switches augment security and performance with built-in layer 3 benefits. Large network deployments can create scalable network architecutres and manage routing between VLANs through Cisco Meraki's intuitive, web-based dashboard.

Specifying Layer 3 subnets and routes

Designed for Reliability & Environmental Efficiency

The Cisco Meraki switch family was designed for reliable, long-lived operation in wiring closet environments, which may be prone to high temperatures and limited ventilation. By minimizing total component count and only using proven switching silicon, Cisco Meraki is able to deliver mean time between failure (MTBF) ratings of over 750,000 hours on products such as the Cisco Meraki MS220-8.

Each Cisco Meraki switch also operates with a split-plane architecture, where silicon-based switching and data forwarding are separated from software-based control and management. By decoupling the underlying switching logic from control, each unit is able to deliver wire-speed switching even when advanced software features such as Layer 7 host and OS fingerprinting are enabled.

Finally, the highly integrated designs of Cisco Meraki switches result in power and cooling savings in large deployment environments of 30- 60% when compared with similar managed Gigabit switches.

Cloud Management:

Cisco Meraki's cloud based management provides centralized visibility & control over Cisco Meraki's wired & wireless networking hardware, without the cost and complexity of wireless controllers or overlay management systems. Integrated with Cisco Meraki's entire product portfolio, cloud management provides feature rich, scalable, and intuitive centralized management for networks of any size.

Cloud Managed Networks

Cisco Meraki's hardware products are built from the ground up for cloud management. As a result, they come out of the box with centralized control, layer 7 device and application visibility, real time web-based diagnostics, monitoring, reporting, and much more.

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.
