Global

Global configuration defines network-wide settings that apply to all NX-OS devices unless explicitly overridden at the device group or device level, providing the foundation layer of the configuration hierarchy. It supports variable definitions for template-based parameterization and template assignments that enable reusable configuration patterns across the entire infrastructure. Global configuration is ideal for establishing consistent baseline settings such as NTP servers, logging parameters, and common routing policies that should be uniform across all managed devices.

Examples

Example 1: Define global variables for use across all devices in a VXLAN fabric

nxos:
  global:
    variables:
      anycast_ip: 10.1.101.1
      ntp_server_1: 10.50.100.1
      ntp_server_2: 10.50.100.2
      syslog_server: 10.50.100.2
      dns_server_1: 10.50.100.20
      dns_server_2: 10.50.100.21
      tacacs_server: 10.50.100.10

Example 2: Global configuration with shared system features and OSPF/PIM baseline applied to all devices

nxos:
  global:
    variables:
      anycast_ip: 10.1.101.1
    configuration:
      feature:
        bfd: true
        bgp: true
        evpn: true
        fabric_forwarding: true
        interface_vlan: true
        nv_overlay: true
        ospf: true
        pim: true
        vn_segment_vlan_based: true
      system:
        hostname: ${hostname}
        mtu: 9216
      interfaces:
        loopbacks:
          - id: 0
            interface_groups: [LOOPBACK_INTERFACE]
            ip_address: ${lo0_ip}/32
      routing:
        ospf_processes:
          - name: "1"
            areas:
              - id: 0.0.0.0
        pim:
          anycast_rp_local_interface_type: loopback
          anycast_rp_local_interface_id: "0"
          anycast_rp_source_interface_type: loopback
          anycast_rp_source_interface_id: "0"
          rps:
            - address: ${anycast_ip}

Example 3: Global configuration with template assignments for reusable service provisioning

nxos:
  global:
    variables:
      anycast_ip: 10.1.101.1
      ntp_server_1: 10.50.100.1
      ntp_server_2: 10.50.100.2
    configuration:
      feature:
        ospf: true
        bgp: true
        pim: true
      system:
        hostname: ${hostname}
        mtu: 9216
    templates:
      - GLOBAL_NTP
      - GLOBAL_LOGGING
