Juniper J Series J6300 — router. Published end-of-sale (last order) and end-of-support (EOSL) dates from Juniper JTAC End-of-Life bulletins.

Every tracked Juniper J Series J6300 SKU group is past Juniper end of service life (last group Apr 2012). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure.
