DES-1210-28/ME cpu load 100%

[lousx]

DES-1210-28/ME

 

System boot version : 1.00.003

System Protocol version : 2.001.004

System firmware version : 6.01.B051

System hardware version : B2

 

 

В fdb свича порядка 200 маков.

 

Не более 10 активных пользователей.

 

Трафик на магистрале не более 10 мбит в секунду.

Клиенты не жалуются пока, но такая нагрузка не дает даже в cli нормально работать.

 

Какие еще необходимы сведения?

[bos9]

если уверены в отсутствии штормов, то попробуйте последовательно отключать используемые фишки и следить за изменением cpu load. начните с acl )

[lousx]

Бося, опять Вы) Убрал acl - нагрузка упала до ~40%

В чем же дело? Правил то было не более 10 и те ip+port привязки.

Странно конечно, всего 10 правил укладывают цпу в полку... Я с данной моделью дела не имел, но свич то, по правде говоря, слабенький. Возможно анализ L3 заголовков для него и вправду предел возможностей ) Или это у вас единичный случай из кучи успешно работающих узлов?

[SmokerMan]

Поставьте последнюю доступную прошивку. Старые тупили даже от транзитных dhcp запросов...

Единичный случай использования этого свича.

Стояла последняя. Откатился чуть назад. Ни какой разницы.

[bos9]

Единичный случай использования этого свича.

 

а в остальном, что используете?

Конфиг покажите.

тогда нет смысла так деградировать ) выкиньте это барахло (DES-1210) и забудьте )

Хотели попробовать в малонаселенный сегмент.
