И вообще, судя по тому, что имеет место быть такое на SSH, следует посмотреть, а если CoPP вообще на железке.

CoPP есть, но не используется.

Кстати, за приведенный пример был бы очень признателен.

Судя по feature navigator, 15.2 последняя версия для 7201. 

Недавно была похожая проблема на 2921 роутере, там решилось обновлением софта.

А в данному случае - возможно, стоит посмотреть настройки доступа ssh и обновить rsa ключи. Но могу ошибаться.
