Может кто подскажет решение проблемы.
суть такова есть роутер cisco 2650XM (c2600-js-mz.122-37.bin) подключен к свитчу WS-C2950T-24 (Fas 0/0 <--> Fas 0/1) на интерфейсе на роутере есть ошибки в частности Input queue (drops) и ignored

в чём проблема непонятно. на обоих сторонах прописано speed 100 full-duplex
загрузка интерфейса порядка 1-2 мегабит. циски обе заземлены, кабель менялся несколько раз, длина кабеля не больше 2 метров. Загрузка процессора порядка 5%. память свободная есть.
думал проблема в системных буферах .. но увы увеличение не дало не какого результата. Так же пробовал изменять Input queue с 75 до 1000.. собственно тоже не дало эффекта.buffers small permanent 250

было замечено что ошибки появляются буквально за пару секунд порядка 30-40 тысяч и потом может пройти минут 10-20 ошибок нет потом опять.. вывалится куча в один момент и всё..
кто что может подсказать .. ????

Вообщем ничего такого что могло бы указать на причину.
Проверьте еще так: интерфейс к компу и пинговать усиленно.
Смотрите есть ли потери. линуксовый ping -f самое то
если есть потери, то морг
я с таким сталкивался - просто битый интерфейс

да и если бы битый интерфейс .. то по моему ошибки должны постепенно увеличиваться а в моем случае они появляются в момент и в большом количестве как вот тут#sho int fa0/0

за 1 секунду откуда не возмись вывалилось 53 тысячи ошибок..
я вот думаю может ли это быть из за памяти такое.. может где то битая память или ещё что
в логах по данной теме нету сообщений..
что-то я запутался во всех этих интерфейсах :)
у вас input errors на интерфейсе роутера?? а на интерфейсе свича что творится (sh run int, sh int)?

>творится (sh run int, sh int)?да на интерфейсе роутера ошибки..
на интерфейсе свитча всё в порядке.. проблем нету...

были подобный дропы на 65, добавление в конфиг mls qos полечило все. есть или нет в вашей циске хз.

а если ошибки при отправке пакета в среду ошибки увеличиваются, но на коммутаторе ошибок на интерефейсе нет - есть некая вероятность сбоя интерфейса маршрутизатора.
1. Уменьшите load-interval на интерфейсах для более наглядной информации
2. Необходимо собрать статистику с обоих интерфейсов, возможно короткий шторм со стороны коммутатора (иммется ввиду кол-во пакетов в единицу вермени)
3. Попробывать на коммутаторе выставить storm-control на интферфейсах в сторону абонентов
Частенько в такой ситуации помогает установка speed и duplex принудительно в 100 и full !!!
