Проверка избыточности модуля Supervisor на коммутаторах Catalyst 4500 Series выполняется с помощью следующих команд: С помощью команды show module можно проверить, что резервный модуль Supervisor существует и находится в режиме ожидания. С помощью команды show redundancy можно проверить сведения использования избыточности. Switch# show redundancy Redundant System Information :
