3-year cost calculator
Pre-filled for Extreme Networks → SONiC. Adjust every figure with your own numbers.
Every figure here is an illustrative estimate, not a vendor quote. Defaults are editable starting points compiled from public information; real, binding pricing comes from the vendor or an authorized distributor. See our methodology.
Recommended for your requirements: Size for 25G access / 100G uplinks across 100 devices. Confirm ASIC is on the target NOS HCL; plan spine/leaf with N+1 and validate BGP/EVPN scale.
All figures are illustrative and fully editable — adjust the cost-per-device and migration inputs with your own numbers. Not guaranteed vendor pricing (defaults reviewed May 2026). For a binding quote, use the request form below to reach an authorized distributor or partner.
