Всё делаю так же, но...
при загрузке:

00:00:19: %LINK-5-CHANGED: Interface Async48, changed state to reset
00:00:24: %LINK-3-UPDOWN: Interface Async48, changed state to down

и потом на sh int :

Чё за беда...
И вообще, почему-то обратиться к этому интерфейсу можно только по номеру (1/1 и т.п. не катит). Кстати, я и line тоже 48 нумерую. Правильно или нет?
