## What the models said about Arista Networks

- "Cisco ACI, Nexus 9000 with extensive features enabled, or overly rich SD‑N stacks can introduce configuration‑driven bugs if not fully tested." (GLM 4.7 FlashX, negative prompt, soft negative)
- "Cons: Premium cost; overkill for basic mid-market unless high-speed uplinks needed." (Grok 4.1 Fast, direct prompt, soft negative)
- "one-half to one-third what a comparable Cisco Catalyst or Arista switch runs" (Muse Glimmer 30B, budget prompt, soft negative)
- "Arista EOS + CloudVision Portal for a greenfield or data-center-focused shop: mature EVPN/VXLAN, CLI familiar, CloudVision management/telemetry overlay, and lower operational overhead" (Muse Glimmer 30B, paraphrase prompt, first choice)
- "Arista is positioned as AI-first with ultra-low-latency AI/ML fabrics, hyperscaler pedigree... AI training clusters favor Arista's buffering and EOS" (Muse Glimmer 30B, comparative prompt, first choice)
- "platforms from Arista (CloudVision), Juniper (Apstra), or Cisco (with careful evaluation) are considered more mature and widely supported" (Mistral Small, negative prompt, first choice)

## What the models said about HPE Aruba

- "HPE Aruba is presented as more budget-friendly, though the result emphasizes campus/edge more than data center." (Perplexity Sonar, budget prompt, soft negative)
- "HPE Aruba (AOS-CX) and Cisco (Catalyst 9000/Nexus) are generally considered the top two contenders" (Qwen 3.7 Flash, direct prompt, first choice)
- "Good for integrated campus+DC, competitive pricing | Less established in pure data center switching use cases" (DeepSeek V4 Flash, scale prompt, alternative)
- "If you need campus + data center: Consider Aruba for campus and Arista for data center" (MiniMax M2.5, budget prompt, alternative)
