Циска 2650 (10.1.252.10) постоянно теряет пакеты. 2-3% процента, любой величины и с любого хоста.
Может ли быть проблема в IOS? Или в аппаратной части? Всё остальное уже проверил.
Вот немного простынок:

Отсюда пингую:

7120#ping 10.1.252.10 repeat 1000 timeout 5

Type escape sequence to abort.
Sending 1000, 100-byte ICMP Echos to 10.1.252.10, timeout is 5 seconds:

Скорость-дуплекс пропиши ручками на порту роутера и на той железке, в которую он воткнут, поменяй патч, посмотри sh int, есть ли ошибочки.

Спасибо.
Проблема оказалась в D-link DES-3026, который определял соединение с циской, как half-duplex, при том, что циска выставляла full. Решилось ручной установкой порта на длинке в Full/100M.
