High Availability Management

Warm Spare configuration in Meraki appliances provides automatic failover capabilities by maintaining a secondary appliance in standby mode, ready to assume primary responsibilities in case of hardware failure or connectivity issues. This functionality ensures business continuity through seamless failover with minimal network disruption, supporting both virtual IP addressing and uplink redundancy for critical network infrastructure. Warm Spare is essential for organizations requiring high availability, minimal downtime, and automated disaster recovery capabilities for their network appliances.

    - name: "!env domain"
      administrator:
        name: "!env org_admin"
      organizations:
        - name: "!env org"
          networks:
            - name: "!env network_name"
