"Cisco2620, один асинхронный порт упал - почему?"
Отправлено Bulat , 06-Июн-04 15:05

Cisco2620, гидра на 32 интерфейса, задействовано 20, все интерфейсы async сконфигурированы одинаково. Все каналы спутниковые 19,2 кБит/с соединены с удаленными серверами и собирают информацию. Один интерфейс async упал и пишет: async41 is reset, line protocol is down.
Сам подозрительный канал протестирован, работает.
Привожу фрагмент ответа на show in:
