About this data
Where the specifications on this page come from
Where does the QFX5120-32C data come from?
The QFX5120-32C specifications on this page are sourced from Juniper Networks' published datasheets and product documentation. SKUit extracts and normalises those values into its product catalog, the same data its BOM builder uses. This page summarises them; it is not Juniper Networks' datasheet, and the original documents are published by Juniper Networks.
Create a validated BOM with the QFX5120-32C
SKUit turns a use case into a complete, orderable bill of materials — the right platform, optics, licences and power, reconciled against the same validated data shown on this page.
To create a bill of materials for the QFX5120-32C, you need to log in or create an account. Log in and you will come straight back to the builder with it selected.
