Возникла необходимость ограничить доступ к управлению железкой. Собрав всю информацию которую получилось (в силу моих возможностей), решил это сделать при помощи COPP (как мне кажется для этого предназначенной фичи). Текущий конфиг COPP (он по сути дефолтный) выглядит так:

Из него видно что политики доступа ssh прописаны в access-list copp-system-acl-ssh в котором по умолчанию всем можно ходить на 22 порт:

IP access list copp-system-acl-ssh
        10 permit tcp any any eq 22
        20 permit tcp any eq 22 any

Изменил acl до следующего состояния:

IP access list copp-system-acl-ssh
        10 permit tcp 10.1.1.0/24 any eq 22

Но доступ к ssh не пропадает даже при 1 deny tcp any any eq 22

 

Подскажите, каким  рабочим способом можно выполнить мою задачу на этом коммутаторе?

COPP это не про доступ к управлению. Это защита control plane от всяких неприятностей.

Вот так делаем. И обычный ACL.

Спасибо, вполне рабочий вариант :).
