Arista EOS Licensing

EOS feature sets are licensed perpetually via License Groups — coarse tiers tied to platform capability. The subscription layer (automation, telemetry, AI Job Observability) is sold separately as CloudVision-as-a-Service.

The Model

Perpetual licenses, tiered by platform

Traditional EOS feature sets — Enhanced L3, Virtualization, FlexRoute, and the rest of the technical feature library — are procured under a perpetual license at a fixed price. The license belongs to the switch and stays with it. The advanced automation, real-time telemetry, and observability features that historically came as add-ons now live in CloudVision-as-a-Service on a monthly subscription term — that's where the recurring revenue model sits.

Fixed Switch Licensing

Group 0 through Group 5

Tier maps to port speed and capability. Entry-level 1G/mG access is Group 0/1; high-density 400G/800G spine sits at Group 4/5.

LIC-FIX-G0 · LIC-FIX-G1

Entry-level 1G and mGig access — out-of-band management, IPMI, low-density edge. Includes platforms like the 7010X.

LIC-FIX-2

10/25G access. Top-of-rack platforms for general-purpose data center workloads.

LIC-FIX-3

100G fixed-config leaf and spine. Platforms like 7260X3 and the high-density mid-tier.

LIC-FIX-4 · LIC-FIX-5

High-density 400G/800G spine. Platforms like 7060X4, 7060X5, 7060X6 for AI fabrics.

Modular Switch Licensing

Tiered by chassis slot capacity

Modular chassis use a separate license-group taxonomy — LIC-MOD-1 for 4-slot, LIC-MOD-2 for 8-slot, LIC-MOD-3 for 12-slot, and LIC-MOD-4 for 16-slot. There's also LIC-MOD-G specifically for modular 1G/mG PoE switches.

Modular Tiers at a Glance

LIC-MOD-1 through LIC-MOD-4

LIC-MOD-1

4-slot modular chassis. Smaller routing/aggregation deployments.

LIC-MOD-2

8-slot modular chassis. Mid-tier routing and DC spine.

LIC-MOD-3 · LIC-MOD-4

12-slot and 16-slot modular chassis. 7800R3 / 7800R4 AI spine class.

LIC-MOD-G

Modular 1G/mG PoE switches — campus and access-aggregation modular platforms.
