L3 switch nima?<\/h2>\n\n\n\n

Layer 3 kommutatori \u2013 bu OSI modelining 3 pog\u2019ona (asosan mac manzili orqali) asosida trafikni uzatuvchi qurilma. Layer 3 switchi barcha kommutatsiya funktsiyalarini qo’llab-quvvatlaydi, shuningdek, VLAN oralig’ida yo’naltirish funktsiyalariga ega.<\/p>\n\n\n
