Feature

Feature configuration enables or disables NX-OS platform features (software services and protocols) that must be activated before they can be configured. Each feature maps to a CLI feature <name> command and controls whether the corresponding service is available on the device. Common features include BGP, OSPF, EVPN, PIM, vPC, HSRP, LACP, LLDP, SSH, DHCP, fabric forwarding, NV overlay, interface-VLAN, MACsec, Netflow, and NGMVPN. Feature enablement is typically one of the first configuration steps when provisioning an NX-OS device and is a prerequisite for all protocol-specific configuration sections.

Examples

Example 1: VXLAN leaf switch with full Spine-Leaf EVPN feature set

nxos:
  devices:
    - name: LEAF1
      configuration:
        feature:
          bgp: true
          ospf: true
