Привет!

На маленьких цисках 2940 наблюдаю престраннейшую херню постоянно растет значение ignored ошибок на порту прихода. При этом сыпется IP-TV. Облазил что что только можно не могу найти причину. Если переткнуть приход в Fa порт то проблема пропадает. Я чето не нашел инфы про тюнинг буферов как их правильно надо настроить. Помоги советом как решить эту проблему. Вот данные о свиче.
