Switch Warm Spare Configuration

Dashboard Location: Switching > Switch Details > Warm Spare

Switch Warm Spare configuration in Meraki networks provides administrators with comprehensive high availability and redundancy capabilities at the device level, enabling automatic failover, seamless network continuity, and reduced downtime through standby switch deployment. This functionality supports enterprise network resilience, business continuity requirements, critical infrastructure protection, and automated recovery mechanisms for maintaining network operations during primary switch failures.

Example-1: The example below demonstrates switch warm spare configuration.

This configuration establishes high availability for switch infrastructure through warm spare redundancy. The example includes spare switch designation, priority settings, and failover parameters for automatic switch redundancy and business continuity.

This configuration configures switch warm spare (VRRP) functionality for device identified by environmental variable “dmz_switch_01” which acts as the primary switch. The configuration enables warm spare with “enabled: true” and designates the spare device using environmental variable “dmz_switch_02”. This creates a VRRP pair. Note that Layer 3 switching must be enabled on the primary before configuration, and each switch requires its own license for VRRP functionality.
