Добрый день!
Вводим в эксплуатацию стэк из двух MES 3348 на замену cisco 3560.
Стэк используем в качестве "ядра" сети.
При подключении наблюдаем сильную загрузку процессора MES-ов, хотя на CISCO все нормально.
Также на блюдаем пинг с провалами устройств находящимися за MES-ми.
Ситуация схожая с обращением viewtopic.php?f=10&t=9480
Поменяли параметр service cpu-rate-limits routing 20 нагрузка спала до 50%.
Подскажите в чем может быть проблема?
show cpu input-rate detailed показывает, что нагрузка CPU в основном на route unknown.
Судя по выводу show tasks util, проблема в сильной загруженности сервиса exRX.
За что отвечает данный сервис?
Вообщем прилагаю show tech-supp

Здравствуйте.

Прошу обновиться на актуальную версию ПО с сайта. Проблема должна решиться после этого.

Хорошо, но уже наверно понедельник.
А параметр service cpu-rate-limits routing 20 оставить или вернуть в дефолтный режим?

Лучше оставить на таком уровне до обновления. Потом можно повысить.

Прошили стэк на новую версию(4.0.13.3), как Вы и рекомендовали.
Загрузка процессора держится на 48 - 58 %.
В архиве after_update вывод tech-supp и вывод команд загрузки процессора, текущие процессы.

Напрягает параметр route unknown почему то самый большой из всех.С чем это может быть связано?
