file name Server IP address BOOT_USER # : FTOS-SI-9-5-0-169.bin : 10.16.127.35 4. Assign an IP address and network mask to the Management Ethernet interface. BOOT_USER # interface management ethernet ip address ip_address_with_mask For example, 10.16.150.106/16. 5. Assign an IP address as the default gateway for the system. default-gateway gateway_ip_address For example, 10.16.150.254. 6. The environment variables are auto saved. 7. Reload the system. BOOT_USER # reload Using Hashes to Verify Software Images Before Installation You can use the MD5 message-digest algorithm or SHA256 Secure Hash Algorithm to validate the software image on the flash drive, after the image has been transferred to the system, but before the image has been installed. The validation calculates a hash value of the downloaded image file on system's flash drive, and, optionally, compares it to a Dell Networking published hash for that file. The MD5 or SHA256 hash provides a method of validating that you have downloaded the original software. Calculating the hash on the local image file, and comparing the result to the hash published for that file on iSupport, provides a high level of confidence that the local copy is exactly the same as the published software image. This validation procedure, and the verify {md5 | sha256} command to support it, can prevent the installation of corrupted or modified images. The verify {md5 | sha256} command calculates and displays the hash of any file on the specified local flash drive. You can compare the displayed hash against the appropriate hash published on i-Support. Optionally, the published hash can be included in the verify {md5 | sha256} command, which will display whether it matches the calculated hash of the indicated file. To validate a software image: 1. Download Dell Networking OS software image file from the iSupport page to the local (FTP or TFTP) server. The published hash for that file is displayed next to the software image file on the iSupport page. 2. Go on to the Dell Networking system and copy the software image to the flash drive, using the copy command. 3. Run the verify {md5 | sha256} [ flash://]img-file [hash-value] command. For example, verify sha256 flash://FTOS-SE-9.5.0.0.bin 4. Compare the generated hash value to the expected hash value published on the iSupport page. Switch Management 85
