"Высокая загрузка CPU, на 3750"
Отправлено gfsergey , 13-Июн-06 05:00

Добрый день!
Есть проблемма в работе WS-C3750G-24TS-1U, прошивка c3750-ipservicesk9-mz.122-25.SED
Есть в наличии 3 разных  VLAN
скорость обмена между хостами внутри VLAN. Скорости 23-28 Mb
когда идет обмен между хостами в разных VLAN скорость копирования 2,3 - 2,7 Мб в сек.
загрузка проца в циске в этот момент 80-100 %
Сильно похоже на неработающий CEF
К примеру общение двух хостов из Vlan 20 и Vlan 3
Создает такую картину
c3750-m#sh proc cpu so 5s
CPU utilization for five seconds: 92%/25%; one minute: 33%; five minutes: 13%
PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process

при этом CEF включен и работает.
