Why this score
  • Past end of service life — 40 months ago
  • Vendor-published date, source-linked
  • Category: ethernet switch

Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated

Figure 1. Extreme Networks issues no software maintenance and no security fixes for this product. Third-party maintenance, spares or replacement are the paths from here. EOSL.ai sells none of them and takes no placement fee.
