Ситуация такая. Стоял в оффисе и ждал своего часа 3627g на замену коммутатора скажем так уровня агрегации. Стоял в оффисе имел два линка один в сторону узла связи с интернетом другой - на коммутатор - этакая тестовая схемка. Работал пару месяцев. Позавчера попытались наконец ввести в экспдуатацию. Сначала посадили восемь отдельных сегментов, суммарно около 15 коммутаторов и около 100 юзеров. Cacti показал на аплинке максимум 40 мегабит, то есть нагрузка не такая уж. Потом один раз подвис... В журналах ничего холодный рестарт - работает. На следующие сутки попытались увеличить нагрузку. Начал зависать, причем интервалы зависания доходить начали до нескольких минут... Сняли. Унесли в офис. Собрали тестовую схемку аналогичную что была ранее. Поработал и выдал (мониторили через COM порт):

и еще много в таком же духе...

Вопрос - это чтото софтовое или все таки железо?
(PS: reset config делали).
PS.PS. Сейчас вообще то поднимает линк через оптику то не поднимает...

С большой долей вероятности что-то аппаратное
