> show interfaces interface-name switching Большое спасибо за пояснение. Ниже привожу sh int. И throttles по всем интерфейсам равен 0. Меня заинтересовала загрузка CPU на моем маршрутизаторе из-за тормозов вещания IPTV при загрузке какого-либо файла из интернета... Просто при использовании DIR-615 таких проблем не было, вот мне и стало интересно, что неужели cisco "хуже" d-link? :)
