EOSL status of Leaf/ToR generations

Arista A-Care sits at the upper market segment — a typical spine-leaf fabric with 24-48 leaf switches quickly becomes a significant annual maintenance budget item. The hardware layer of the leaf switches is comparatively simple (single-ASIC boxes without modular chassis), the complexity lies in the EOS software stack with MLAG, EVPN-VXLAN, IP Fabric and CloudVision integration. TPM uses this separation — we replace hardware maintenance (power supplies, fan trays, optics, box replacement if needed) at 40-50 percent of the A-Care price, EOS and CloudVision continue independently.

We service Arista Leaf/ToR switches with OEM power supplies, fan trays and optics from our own warehouse. 7050X series has gone through several generations over the years (X, X2, X3) — components are not interchangeable across generations, so we stock all variants. For low-latency 7150/7160 switches, hardware components are identical to 7050X, but EOS configuration is optimized for sub-µs latency — TPM does not affect latency optimization because EOS remains unchanged.

The full OEM-vs-TPM matrix (spare parts, SLA tiers, language, sub-outsourcing, compliance docs, reporting) is the same for every Arista Networks line — see the Arista Networks battle card.

BAIT/MaRisk documentation package, DORA Art. 28 contract template, ISO 27001 and GDPR-compliant media handling apply identically to every Arista Networks line — details on the Arista Networks battle card.

Same four steps for every Arista Networks line: inventory → fixed-price quote in 48 h → contract (BAIT/MaRisk/DORA hooks) → hand-over with spare-parts provisioning. Details on the Arista Networks battle card.

Which Arista Leaf/ToR models do you service?

Complete Leaf/ToR family: 7050X series (all generations X, X2, X3 with SX/QX/TX variants), 7060X series (7060CX-32S, 7060CX2-32S, 7060PX4-32, 7060SX2-48 for 100/400G), 7150/7160 (7150S-24/52, 7160-32/48 for low-latency trading and HPC) and the older 7020/7010T line (7020TR-48, 7010T-48, EOSL reached). Including all power supplies, fan trays and optics modules.

What does TPM cost for Arista Leaf compared to A-Care?

30 to 60 percent savings. For a 7050X3-48S leaf with 24×7×4, TechCare is roughly 55% below the Arista price. For a complete spine-leaf fabric with 32 leaf switches, TechCare is roughly 55–60% below Arista A-Care. For EOSL 7020/7010T fleets we see up to 70 percent — Arista often no longer offers renewal.

Do EOS, MLAG and EVPN-VXLAN continue to work without an Arista contract?

Yes. EOS (Extensible Operating System), MLAG (Multi-Chassis Link Aggregation), EVPN-VXLAN, IP Fabric, all layer 2/3 functions, OSPF/BGP/IS-IS and VXLAN tunneling continue without licensing — they are part of the EOS firmware. EOS updates to newer versions require an active Arista contract. Usually uncritical with stable spine-leaf configurations — many customers run 4-6 years on the same EOS version.

What about Arista CloudVision?

CloudVision (CVP) is Arista's central management and telemetry platform — software subscription independent of hardware maintenance. Customers actively using CloudVision for configuration management, streaming telemetry, NetDB or the application visibility features should keep the CVP subscription with Arista — hardware maintenance runs in parallel via TPM. Switch-to-CVP integration and all CloudVision functions stay functionally active.

Can you service EOSL 7020/7010T and older 7050X?

Yes, a focus area of our Arista business. 7020/7010T (released 2014-2015, EOSL 2022-2023) and early 7050X generation (2013-2015, EOSL 2022-2024) are still productive in DACH data centers — typically in stable spine-leaf fabrics that don't necessarily need refresh. We stock switches, power supplies, fan trays and optics for these generations. EOS on older 7050X continues to work.

Which SLA levels do you recommend for leaf switches?

Spine-leaf fabrics are redundantly designed — leaf switches typically work as MLAG pair, a leaf failure is absorbed by the partner. 5×9 NBD is therefore economically appropriate for most leaf sites. For low-latency 7150/7160 in trading environments, 24×7×4 with German-speaking onsite engineer is standard — trading outage has direct penalty risks. Multi-site contracts with mixed SLA levels are standard in practice.
