Overview

Structure

Section titled “Structure”

The NX-OS data model documentation is divided into the following sections:

  • Inventory: The building blocks of the data model, such as global, devices, device_groups, interface_groups and templates.
  • System: Device-wide system settings, such as hostname, boot, hardware resources, features, clock, DNS, NTP and management access.
  • Interface: Ethernet, port-channel, subinterface, loopback, SVI and management interfaces, and global interface settings.
  • Layer 2: VLANs, spanning tree, vPC, VTP, link-layer protocols (LACP, LLDP, CDP, UDLD), IGMP snooping and the MAC address table.
  • Routing: Routing protocols, static routes, VRFs, BFD and HSRP.
  • Routing Policy: Route maps, prefix lists, community lists and AS-path access lists.
  • IP Services: ARP, IPv6 neighbor discovery, DHCP, ePBR, IP SLA and object tracking.
  • Overlay: VXLAN EVPN, fabric forwarding and the NVE interface.
  • Security: AAA, access lists, object groups, key chains, MACsec, security groups and Hypershield.
  • QoS: Classification and marking, queuing and network QoS policies.
  • Monitoring: Logging, SNMP, telemetry, analytics, NetFlow, sFlow and SPAN.

Interface-level protocol settings, such as OSPF or PIM on an interface, are documented on the respective protocol pages.

Additional Resources

Section titled “Additional Resources”

The Data Model describes how to create resources but not what functional purpose they serve within the NX-OS configuration. For more information about NX-OS please visit the documentation.
