[Spectrum-X Configuration] When creating a simu-lation in NVIDIA AIR, what syntax would you use to define a link between port 1 on spine-01 and port…

NVIDIA AIR uses a YAML-based syntax to define network topologies. Links between devices are specified in a links.yml file. The correct format for defining a single link is a string: "":"" - "":"". NVIDIA Spectrum switches, commonly simulated in AIR, use the swp convention for front-panel switch ports. Therefore, the syntax correctly identifies the spine and leaf hosts, uses the swp port naming convention, and connects them with a hyphen. The asterisks in the option are likely typographical errors, but the fundamental syntax and naming convention are correct.

B. This option is incorrect because it uses the word "to" as a separator, whereas NVIDIA AIR link definitions require a hyphen (-).

C. This option is incorrect for two reasons: it uses the "eth" port naming convention, which is not standard for Spectrum switch fabric ports, and it uses the wrong "to" separator.

D. This option uses the correct hyphen separator but employs the incorrect "eth" port naming convention for switch fabric ports, which should be swp.

1. NVIDIA Air User Guide: In the "Building a Custom Topology" section, the documentation specifies the format for the links.yml file. It provides examples showing the "":"" - "":"" syntax. (Reference: NVIDIA Air User Guide, Chapter 4: Building a Custom Topology, Section: links.yml).

2. NVIDIA Cumulus Linux User Guide: The documentation for Cumulus Linux, which is often the network operating system simulated by NVIDIA AIR, details the port naming convention. It specifies that front-panel ports on NVIDIA Spectrum switches are named swp. (Reference: Cumulus Linux 5.8 User Guide, Chapter: Interfaces, Section: Interface Naming).
