Switch DHCP Server Policy Configuration

Dashboard Location: Switching > DHCP Servers and ARP

DHCP Security Policy Management

Switch DHCP server policy configuration in Meraki networks provides administrators with comprehensive DHCP security controls, enabling network protection against rogue DHCP servers, ARP spoofing attacks, and unauthorized network services. This functionality supports DHCP server validation, ARP inspection, policy enforcement, email alerting, and network traffic monitoring. DHCP server policies are essential for maintaining network integrity, preventing IP address conflicts, securing Layer 2 communications, and ensuring reliable network services in enterprise environments.

Examples

Example-1: The example below demonstrates switch DHCP server policy configuration using tested YAML configuration from pipeline fixtures.

meraki:
  domains:
    - name: !env domain
      administrator:
        name: !env org_admin
      organizations:
        - name: !env org
          networks:
            - name: !env network_name
              product_types:
                - appliance
                - switch
                - wireless
                - camera
                - sensor
                - cellularGateway
              switch:
                dhcp_server_policy:
                  default_policy: block
                  allowed_servers:
                    - 00:50:56:00:00:01
                    - 00:50:56:00:00:02
                  blocked_servers:
                    - 00:50:56:00:00:03
