MS22 & MS42 Cloud Managed
Switch Families
The Meraki MS is the world’s first cloud-managed switch bringing the
benefits of the cloud: simplified management, reduced complexity,
network wide visibility and control, and lower cost for branch and
campus deployments.
A Fresh Approach
Meraki switches are built from the ground up to be easy to manage
without compromising any of the power and flexibility traditionally
found in enterprise-class switches.
Meraki switches are managed through an elegant, intuitive cloud
interface, rather than a cryptic command line. To bring up a Meraki
switch, just plug it in; there’s no need for complicated configuration
files — or pre-staging.
In addition, Meraki’s centralized management system gives
administrators deep visibility into the network and how it’s used. See
which switches are near capacity across hundreds of sites. Find all
configuration changes made by a certain person with instant search.
Industry-Leading Cloud
Cloud management has a number of benefits that make it easier
to build networks large and small:
• Single pane of glass management of distributed switch
deployments, wireless APs, and firewalls across multiple sites
through the browser.
• Virtual stacking: manage up to tens of thousands of ports from a
single pane of glass.
• Layer 7 OS, client, and hostname fingerprinting.
• Powerful Live Tools such as cable test to isolate physical layer
• E-mail and SMS (text) alerts upon power loss, downtime, or
configuration changes.1
• Role-based administration and automatic, scheduled firmware
upgrades over the web.
• Regular feature updates and enhancements delivered on
demand from the Meraki cloud.
• No staging deployments

Meraki switches include all of the traditional Ethernet features found
on the highest end products, including:
• Four built-in small form-factor pluggable transceivers (SFP / SFP+),
• Quality-of-Service (QoS) to prioritize mission critical traffic such
as voice and video
• GbE and 10 GbE uplink ports for high-speed connectivity to
aggregation layer switches or other upstream devices
• Wire-speed switch fabric (up to 176 Gbps) and QoS queues per
port for converged voice, video, and data deployments
• Low power consumption, quiet acoustic designs, and shallow rack
depth, which enable flexible deployment in wiring closets as well
as offices and classrooms
• IEEE 802.1X support for port based network access control
• MAC-based RADIUS auth and MAC whitelisting
• Voice VLAN support for simplified VoIP deployments
• Port Mirroring to monitor network traffic

cameras, and other PoE enabled devices
• IGMP Snooping to optimize network performance with
multicast traffic
• Lifetime hardware warranty and advanced replacement at no
additional cost
• Link Aggregation Control Protocol (LACP) for high-capacity
trunking, stacking, and increased availability
• Broadcast storm protection, spanning tree, BPDU guard, root
guard, and other safeguards to guard against misconfigurations
and reduce convergence time
• Per port VLAN configuration
• Multiple administrative roles with sophisticated security policy

Meraki Cloud Management Architecture
Combined Views of Thousands of Ports
Scheduled Firmware Updates
Automatic E-mail Alerts
Simplified Management and
Meraki’s cloud managed architecture makes it simpler than ever to
quickly provision and reconfigure switch ports with security, QoS,
and other parameters. The Meraki dashboard provides unified
policies, event logs, and monitoring, which make it easy to manage
and grow large network deployments.
Layer 7 Visibility
Meraki is the only switch to include 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.
By providing a complete, powerful set of management functions over
the web, Meraki’s cloud-based management eliminates the need
for proprietary command line configuration interfaces which require
expensive and time consuming certifications. 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 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.

Converged Voice, Video and Data Environments
Meraki’s Unified Software Architecture
The Meraki switch family is designed to unify data, voice, and video
onto a single IP backbone. All Meraki switches support rich qualityof-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.
Meraki switches run the same Meraki operating system used by
Meraki’s firewalls and wireless LAN products. The use of a common
operating system allows Meraki to deliver a consistent experience
across all product lines.
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 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, Meraki switches support the industrystandard Link Layer Discovery Protocol (LLDP), enabling switches to
automatically discover Ethernet-enabled devices, determine their
power requirements and join the correct virtual

Designed for Reliability & Environmental Efficiency
The 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, Meraki is able to
deliver mean time between failure (MTBF) ratings of over 475,000
hours on products such as the Meraki MS22.
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 Meraki switches result in
power and cooling savings in large deployment environments of 3060% when compared with similar managed Gigabit switches.
Each 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
Distributed Branches & Remote Sites
Campus Edge
Meraki’s cloud-based system makes it easy to manage a single
switch, or thousands of distributed switches, from a single interface.
MS switches are ideal for small and large scale campus deployments,
where reliability, scalability, and managability are top priorities.
• Troubleshoot problems remotely, e.g., find which port has a bad
cable attached.
• Virtual Stacking lets administators manage up to tens of thousands
of ports in a single interface without having to physically connect
stack members.
• Add or replace switches without having to send a technician
onsite. Switches automatically download their current configuration
as soon as they are connected to the network.
• Receive email alerts or SMS messages whenever there’s a
problem at a remote site.1
• 10 GbE cable SFP+ ports with link aggregation provide high speed
connectivity to distribution or core switches.
• Get alerts when any switch fails or goes offline, before users
