Добрый день!
Из-за нехватки памяти не удается сохранить running-config в startup-config. Подскажите, что сделать, чтобы решить эту проблему. Боюсь, что если перезапустить, будут сложности с чтением startup-config, так как после попытки erase nvram: он пуст, а скопировать из бэкапа не дает.

c2811gw#copy running-config startup-config
Destination filename [startup-config]?
startup-config file open failed (Not enough space)

%ERROR: Not able to process Signature in nvram:/startup-config.
