​Arista Software License Framework

Arista licensing for software offerings span across physical devices, virtual software platforms, on-prem and cloud-based management offerings via EOS, CloudEOS, CloudVision, CloudVision WiFi, Converged Cloud Fabric, DANZ Monitoring Fabric and MOS software. The licensing model is designed to provide flexibility and consistency, both in the choice of the appropriate feature functionality and in the software consumption model. Arista software licenses are perpetual, unless a term is mentioned in the SKUs. Perpetual licenses are not transferable among products without written authorization from Arista.

Arista EOS Licensing

EOS license SKUs provide the right to use advanced features on Arista switching and routing platforms and covers a variety of use cases in data center, routing, campus etc. These licenses are perpetual and applied on a per-device basis. Licenses are first divided into fixed and modular platforms categories and then further divided into tiers based on the platform capacity, bandwidth, scalability etc. of the platforms, then finally divided by the feature set included in the license.

Fixed Switching Platforms (FIX-X)

The perpetual license on Arista fixed configuration switches are subdivided into platform classes 1, 2, 3, 4, or MG based on the various attributes such as chip capacity, system features, port speeds, etc.

Modular Switching Platforms (MOD-X)

EOS perpetual licenses for modular switches are based on the total number of line card slots. Each of the licenses are subdivided into the following platform classes:

  • X=1: Modular switches with 4-line card slots

  • X=2: Modular switches with 8-line card slots

  • X=3: Modular switches with 12-line card slots

  • X=4: Modular switches with 16-line card slots

  • SS-EOS-Enh-FIX2-1M: EOS Subscription for 1-Month includes EOS E/V/Z/FLX-LITE Licenses and ACare support for 2RU systems

Arista MOS Software

The Arista 7130 Series products include license to Arista MOS, which provides system monitoring, FPGA image management, and other critical resources to allow developers to concentrate on their core application value. There are no separate SKUs.

Arista Converged Cloud Fabric and DANZ Monitoring Fabric
