Сорри, возможно глупый вопрос, но яндекс, гугль и пр. ничего не дали.
На сервере slackware 12 и гигабитная карта. Как на ней включить flowcontrol (средствами линукса)?
Сервер гигабитной картой включен в каталист 3750 (у него тоже гигабитные интерфейсы) по меди. на серверной стороне постоянно сыпятся ошибки:

Вроде между каталистами такие проблемы решались включением flowcontrol.
Может и в моем случае поможет.
