Коммутатор Cisco WS-X6708-10G-3C

Описание товара

8-портовый 10-гигабитный оптический модуль поддерживающий до 66 портов 10 Gigabit Ethernet в одном шасси Cisco Catalyst 6509 и 132 порта 10 Gigabit Ethernet в VSS. WS-X6708-10G-3C поддерживает локальную коммутацию на 64 Гбит/с, что делает его идеальным для развертывания на уровне ядра или агрегации в кампусах LAN и центрах обработки данных. Все 8 портов могут использоваться для создания виртуального коммутатора в VSS.
