Привет.
Вот это настораживает
Цитата
Slad, предлагаю обнулить счетчики и еще раз посмотреть, насколько они вырастают после сесии ssh. Думаю, стоит ожидать, что счетчик overrun опять что-то насчитает. Если он растет - значит, если верить этому документу
http://www.verio.com/support/documents/vie....cfm?doc_id=482, то 'input rate exceeded the receiver's ability to handle the data'.
И покажите, пожалуйста, еще раз свежие выводы 'sh interface' с 3750 с транка этого и с 65 с интерфейсов gi 1/11 и 1/13... Сначала все счетчики обнулите, потом установите сессию и снимите после сессии инфу. Окей?
Дополните еще схему, пожалуйста, скоростями интерфейсов... Ок? Будет нагляднее. Есть одно предположение, но могу ошибаться. Подтвердите, пожалуйста, а на серверах у вас интерфейсы 100-мегабитные.. ? И еще покажите с серверов вывод 'netstat -ni' или аналогичную статистику с интерфейса.
P.S. Если кто найдет такое же понятное объяснение значений вывода команды 'sh interface' на cisco.com, дайте, пожалуйста, ссылку.. Так сказать, на первоисточник. Спасибо.
очистил счетчики, зашел по ssh на фтп:
