Пинг у вас рваный – неестественный.
У меня сервисники спрятаны в изолированой сети – общаются только с HMC, которая работает в качестве DHCP. Пинги между HMC и FSP всегда ровные от 200 до 600 милисекунд.
Сетевые проблемы есть, но они не связаны с версией FSP, а касаются логики работы DHCP на консоли.

А в общей сети может быть все, что угодно.
Сейчас копаюсь в логах консоли и нашел даже следы атак KIDO. Консоль одним портом выходит в общую сетку. На него периодически стучится эта зараза – стучит по портам и следом через 30 секунд идет серия попыток зацепиться перебором паролей.
