About This Product
The Meraki MS125-48LP 48-Port Layer 2 Cloud Managed Stackable Gigabit PoE+ Switch is built from the ground up for cloud management without compromising any of the power and flexibility traditionally found in enterprise-class switches. The MS125-48LP is managed through an elegant, intuitive cloud interface, rather than a cryptic command line. To bring up this Meraki switch, simply plug it in. This switch doesn't require CLI for switch configuration or port management. Meraki’s centralised management platform gives administrators granular visibility into their network, and their dashboard helps you keep track of every configuration change in your network with detailed event and change logs.

Industry Leading Cloud Management
Cloud management has a number of benefits that make it easier to build networks large and small:

• Automatic email alerts from power loss, downtime, excessive Layer 1 errors, or configuration changes
• Powerful remote diagnostic tools such as packet capture to help isolate and troubleshoot network issues
• Role-based administration
• Firmware upgrades and enhancements from the Meraki cloud
• Virtual Stacking enables switch port configuration changes on the dashboard interface without the need to physically stack switches
• Incredible network transparency with application, operating system, client, and hostname visibility
• Zero-touch provisioning for rapid deployment across sites
  
  

Branch & Campus Access

• Quality-of-Service (QoS) to prioritise mission critical traffic such as voice and video
• Voice VLAN support for simplified VoIP deployments
• CDP/LLDP with detailed neighbour discovery and visibility
• Port Mirroring support for monitoring network traffic at line rate
• IGMP Snooping to optimise network performance for multicast applications
• Link Aggregation Control Protocol (LACP) for high-capacity trunking
  
  

Network Security

• IEEE 802.1X, MAB, and Hybrid authentication support for wired access control with RADIUS server monitoring
• ACL support (IPv4 & IPv6) and MAC whitelisting
• Single-Host/Multi-Domain/Multi-Host/Multi Authentication
• Change of Authorisation (CoA) and RADIUS accounting support
• DHCP snooping to prevent users from adding unauthorised DHCP servers on the network
• Rapid spanning tree, BPDU guard, root guard, loop guard, UDLD & other safeguards to help prevent misconfigurations and reduce convergence time
• Per-port VLAN configuration
• Multiple administrative roles with sophisticated security policy management
  
  

Network Troubleshooting & Automation

• Virtual Stacking helps IT admins make configuration changes to hundreds of switch ports in seconds with Meraki's intuitive dashboard interface
• Configuration templates for rapid, zero-touch provisioning and auditing of all sites
• Network Topology for automatic and interactive network mapping
• Remote cable testing, packet capture and client discovery
• Automatic and scheduled firmware upgrades for the complete network
  
  

Converged Voice, Video and Data Environments
The MS125-48LP is designed to unify data, voice, and video onto a single IP backbone. Like all Meraki switches, it supports rich quality-of-service (QoS) functionality for prioritising data, voice, and video traffic. The switch supports eight class-of-service (CoS) queues on every port, enabling them to maintain end-to-end traffic prioritisation. PoE provides power to VoIP telephones, IP security cameras, wireless access points (APs), and other IP devices. In addition, using CDP and LLDP, PoE power is intelligently budgeted to maximise the number of PoE clients supported.

Application Layer Visibility
The Meraki MS125-48LP switch includes integrated Layer 7 fingerprinting without the need to purchase additional modules or services. Identify hundreds of applications from business apps to BitTorrent and YouTube. User fingerprinting allows administrators to quickly identify individual users by device and tune network resources for optimum performance.

Unified Software Architecture
The MS125-48LP runs the same operating system used by all of Meraki's products, which allows Meraki to deliver a consistent user experience for network management. When connected, new MS125-48LP switches automatically reach out to the Meraki cloud and download the most current configuration. Future updates can be user-scheduled, ensuring the network is kept up-to-date with bug fixes, security updates, and new features.

Simplified Management and Operations
The Meraki 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 scale network deployments.

By providing a complete, powerful set of management functions over the cloud, Meraki cloud-based management eliminates the need for proprietary command line configuration interfaces which require expensive and time-consuming certifications. The Meraki MS125-48LP switch 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 pounds in time and travel expenses.

The Meraki MS125-48LP switch 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.

Designed for Reliability & Environmental Efficiency
The Meraki MS125-48LP switch was designed for reliable operation in network closet environments, which may be prone to high temperatures and limited ventilation. By minimising total component count and only using proven switching silicon, Meraki is able to deliver a highly reliable switch with exceptional mean time between failure (MTBF) ratings.

This 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 design of the Meraki MS125-48LP switch results in power and cooling savings in large deployment environments of 30- 60% when compared with similar managed Gigabit switches.

Distributed Branches & Remote Sites
The Meraki cloud-based system makes it easy to manage a single switch, or thousands of distributed switches, from a single interface.

• Troubleshoot problems remotely, e.g. find which port has a bad cable attached.
• 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.
  
  

Campus Edge
MS125-48LP switches are ideal for small and large scale campus deployments, where reliability, scalability, and manageability are top priorities.

• Virtual Stacking helps IT admins control port access policies, apply VLANs, toggle port power and more.
• 10GbE cable SFP+ ports with link aggregation provide long range connectivity to aggregation switches such as the MS425 (sold separately).
• Get alerts if any switch fails or goes offline, before users complain.
