Имеется Cisco 7204. В течение нескольких недель наблюдается слкдующая проблема. При мониторинге загрузки камня вплываеют пики под сто процентов. Т.е. вредняя загрузка порядка 60 - 70 процентов, но каждые 10 - 15 секунд камень резко нагружается в полку. При таком поведении Cisco происходит задержки пинга, а иногда и потеря пакета.
Среднее количество переливаемого трафика на fa 0/0 - 30 Мегабит на fa 0/1 - 40 Мег. Пробовали послушать трафик, однако ничего подозрительного результат не показал - просто обычная работа клиентов. Помогите господа админы, может кто то сталкивался с такой проблемой?
