“ Introduction

Cisco Meraki is a cloud-managed network solution that combines RF excellence with simplicity and scalability. This document provides best practices for configuring and deploying Meraki Wireless networks in large-scale enterprises, focusing on common settings that apply to most wireless network implementations.

“ Large Campus Design for Meraki Wireless

For large campus deployments, Meraki Wireless is recommended to be deployed with at most 800 APs and 10K clients per Meraki Network. It uses a distributed data plane approach, where MR access points locally switch all wireless traffic. This design requires careful planning of roaming domains and switching architecture. Key considerations include configuring trunk ports for APs, designing distribution layer switches, and planning for Layer 2 or Layer 3 roaming.

“ Network Services Guidelines

This section covers guidelines for RADIUS, DHCP, DNS, and firewall configurations. For RADIUS, it's recommended to summarize AP management subnets and consider using load balancers for large deployments. DHCP scope sizing should account for all possible devices, with lease times aligned to average dwell times. DNS and firewall configurations should be optimized for performance and scale.

“ SSID Configuration

Meraki Wireless SSIDs can be configured in three modes: Tunneled, Distributed, and Remote Worker. It's recommended to use no more than 3 SSIDs per AP, with a maximum of 15 SSIDs per Meraki Network. Bridge Mode SSIDs are recommended for large-scale deployments. For 6 GHz WPA3 design, three migration paths are suggested: 'All-In', 'Multiple SSIDs', and 'One SSID' options.

“ Quality of Service Guidelines

QoS plays a crucial role in prioritizing and reliably delivering certain types of data. Guidelines include setting SSID priorities, matching DSCP values across the network, and applying consistent policies between sites. Traffic shaping should be done per client and per application, rather than as a top-down enforcement for the entire SSID.

“ Access Point Radio Configuration

This section covers client load balancing, wireless mesh networking, and AI-Powered Auto RF. For high-density deployments, it's recommended to turn off Client Balancing. Auto RF should be enabled to optimize radio settings in real-time, with AI Channel Planning enabled to maintain an optimal channel avoid list.

“ Infrastructure Management

Firmware management is simplified through Meraki's cloud-based dashboard. Best practices include running the same MR version within a roaming domain, avoiding beta firmware on production networks, and designating test areas for new firmware validation. The firmware upgrade strategy should consider whether clients need to stay connected during the upgrade process.
