"Загрузка CPU на Cisco 881" Отправлено ViT, 08-Фев-17 15:53
Добрый день, всем! Прошу у вас помощи разобраться в проблеме с загрузкой CPU на cisco 881. Сразу обозначусь, что данная циска является домашним роутером и за NATом находятся несколько устройств, в том числе 2 приставки под IPTV. Ниже прикладываю show run и show processes. Процессор загружается даже если запустить speedtest. Как вы видите из sh process, что 98% cpu уходит на обработку прерываний. Так вот вопрос, что с этим можно сделать?
