Questions & Answers
What is Cisco flash memory?
Cisco flash memory is non-volatile storage on routers and switches that holds the OS image, configuration files, and logs. It retains data without power and enables device boot and software upgrades.
What is the difference between Cisco flash and NVRAM?
Cisco flash stores IOS images, files, and logs persistently, while NVRAM holds the device’s running-configuration only. Flash capacity is larger for software storage; NVRAM is optimized for config retention.
How do I check flash memory usage on a Cisco device?
Run the CLI command show flash: or show file systems to display total, used, and free flash space. Look for “flash:” or “bootflash:” entries to view detailed usage statistics.
How can I free up space on Cisco flash memory?
Delete unneeded files with delete flash: or archive old IOS images to a TFTP/FTP server using the copy command. Then verify free space with show flash:.
