Single LAN Management

Single LAN configuration in Meraki appliances provides simplified network setup for environments requiring a single, unified network segment without VLAN complexity. This functionality enables organizations to deploy straightforward network configurations while maintaining comprehensive security and management capabilities. Single LAN mode is ideal for small offices, branch locations, and scenarios where network segmentation is not required, offering simplified administration while preserving advanced appliance features.

Examples

Example-1: The example below demonstrates single LAN configuration.

This configuration manages the primary LAN interface settings for appliances in routed mode. The example includes subnet definitions, DHCP settings, and basic network parameters for single-subnet deployments.

This configuration establishes a single LAN segment using “subnet: 192.168.1.0/24” with the appliance serving as the default gateway at “appliance_ip: 192.168.1.1”. The “mandatory_dhcp: false” setting allows devices to use static IP addresses within the subnet range, providing flexibility for servers and network equipment that require fixed addressing. This simplified configuration eliminates VLAN complexity while maintaining full appliance functionality including firewall, VPN, and traffic shaping capabilities.
