Как просмотреть / сбросить статистику ошибок / показателей на интерфейсах Cisco

Собственно эти 2 команды: просмотр статистики show interface ИмяИнтерфейса и сброс счетчиков clear counters ИмяИнтерфейса.

router#clear counters tunnel1
Clear "show interface" counters on this interface [confirm]y
router#

Ну и за комнанию сброс счетчиков на ACL листах - команда clear ip access-list counters.

router#clear ip access-list counters ?
  <1-199>      Access list number
  <1300-2699>  Access list number (expanded range)
  WORD         ACL Name

It анекдот

Мой сын точно будет хакером - он еще в презервативе нашел уязвимость.
