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. After enabling and configuring startup configuration verification, the device verifies the hash checksum of the startup configuration during every reload. DellEMC# verified boot hash startup-config 619A8C1B7A2BC9692A221E2151B9DA9E 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 88 Management
