[mikhajjlovskijj]

Изначально на версии JunOS qfx-5e-17.2R2.8 не заводились VC-ports на 100G, после обновления на 17.4R1.16 порты стали определяться в VC.

•   Включаем preprovisioned configuration mode

set virtual-chassis preprovisioned

•   Добавляем свитчи в стек

set virtual-chassis member 0 serial-number abc123 role routing-engine
set virtual-chassis member 1 serial-number abc456 role routing-engine

•   Если свитча два

set virtual-chassis no-split-detection

•   Далее:

set system commit synchronize
set chassis redundancy graceful-switchover
set protocols layer2-control nonstop-bridging
set routing-options nonstop-routing

•   настраиваем порты VC-port

request virtual-chassis vc-port set pic-slot 0 port 48
request virtual-chassis vc-port set pic-slot 0 port 51

•   Включаем второй коммутатор и настраиваем на нем так же VC-port
•   Итого
