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.
After enabling and configuring startup configuration verification, the device verifies the hash checksum of the startup configuration during
every reload.

Configuring the root User Password
For added security, you can change the root user password.
If you configure the secure-cli command on the system, the Dell EMC Networking OS resets any previously-configured root access
password without displaying any warning message. With the secure-cli command enabled on the system, the CONFIGURATION
mode does not display the root access password option.
To change the default root user password, follow these steps:
• Change the default root user password.
CONFIGURATION mode
root-access password [encryption-type] root-password
Enter an encryption type for the root password.
• 0 directs the system to store the password as clear text.
• 7 directs the system to store the password with a dynamic salt.
• 9 directs the system to encrypt the clear text password and store the encrypted password in an inaccessible location.
When you configure the root access password, ensure that your password meets the following criteria:
• A minimum of eight characters in length
• A minimum of one lower case letter (a to z)
• A minimum of one upper case letter (A to Z)
• A minimum of one numeric character (0 to 9)
• A minimum of one special character including a space (" !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~")

Locking Access to GRUB Interface
You can configure the Dell EMC Networking OS to lock the GRUB interface using a password. If you configure a GRUB password, the
system prompts for the password when you try to access the GRUB interface.
CAUTION:
After configuring the boot access password, save it to a secure location. If you forget it, you will not be able
to access the options in the startup menu. If you forget both the boot access password and the enable password, the
system may become inaccessible.
To lock the GRUB interface using a password, use the following procedure:
