Startup Configuration Verification
Dell EMC Networking OS comes with startup configuration verification feature. When enabled, it checks the integrity of the
startup configuration that the system uses while the system reboots and loads only if it is intact.
Important Points to Remember
● The startup configuration verification feature is disabled by default on the Dell EMC Networking OS.
● The feature is supported for startup configuration files stored in the local system only.
● The feature is not supported when the fastboot or the warmboot features are enabled on the system.
● If the startup configuration verification fails after a reload, the system does not load your startup configuration.
● After enabling the startup configuration verification feature, use the verified boot hash command to verify and store
the hash value. If you don’t store the hash value, you cannot reboot the device until you verify the image hash.
● If OS image verification fails, the system does not load your startup configuration and displays an error message until you
remove the verified boot command from the configuration.
Dell EMC Networking OS Behavior after System Power-Cycle
If the system reboots due reasons such as power-cycle, the current startup configuration may be different than the one you
verified the hash using the verified boot hash command. When the system comes up, the system may use the last-
verified startup configuration.
Dell EMC Networking recommends backing up the startup configuration to a safe location after you use the verified boot
hash command. When the startup configuration verification fails, you can restore it from the backup.
The system continues to display a message stating that startup configuration verification failed. You can disable the startup
configuration feature either by disabling startup configuration verification or save the running configuration to the startup
configuration and update the hash for the startup configuration.
Enabling and Configuring Startup Configuration Hash Verification
To enable and configure startup configuration hash verification, follow these steps:
1. Enable the startup configuration hash verification feature.
CONFIGURATION mode
verified startup-config
2. Generate the hash checksum for your startup configuration file.
EXEC Privilege
generate hash {md5 | sha1 | sha256} {flash://filename | startup-config}
3. Verify the hash checksum of the current startup configuration on the local file system.
EXEC Privilege
verified boot hash startup—config hash-value
NOTE:
The verified boot hash command is only applicable for the startup configuration file in the local file
system.
