Имеется Cisco 7609 с мозгами RSP720-3CXL-GE, и ethernet модулем на 48 гигабитных SFP WS-X6748-SFP c плиткой WS-F6700-DFC3CXL. Все это хозяйство испытвает проблемы от высокой загрузки CPU, это при том что нагрузка на нее подана детская, а именно:
1) Принимает full-view от двух провайдеров. Поток трафика в пики гигабит на входящий, 500 мегабит исходящий
2) Подняты 3 L2-транка (протокол Lacp) два с агрегационными узлами и один с интернет провайдером
3) Подключены еще 4 слабонагруженных узла.
Итого на ethernet модуле используются 11 портов из 48. С общей нагрузкой в пиках не более 6 Гигабит/с
4) Явлется транзитом для тунелированного трафика GRE в 1 Гбит/с
5) Мультикаст маршрутизатор, доля мультикаст трафика очень мала чтобы на нее грешить.
NAT-ом практически не занимается (занатил несколько сервером и пару рабочих компов для технических нужд) в пиках не более 2000 трансляций.CEF включен на всех ip интерфейсах.
Из security используются технологии ip arp inspection и ip dhcp snooping.
Загрузка вечерами под 80%, что очень много для такого маленького потока трафика. У меня на порядки загруженней узлах стоит cisco 3750 и загрузка выше 40 не поднимается (правда без BGP).
