Setup Guide
However, these changes are backward-compatible and do not aect existing behavior; meaning, you can still use the ip http source-
interface command to communicate with a particular interface even if no VRF is congured on that interface
NOTE: If the HTTP service is not VRF-aware, then it uses the global routing table to perform the look-up.
To enable an HTTP client to look up the VRF table corresponding to either management VRF or any nondefault VRF, use the ip http
vrf
command in CONFIGURATION mode.
• Congure an HTTP client with a VRF that is used to connect to the HTTP server.
CONFIGURATION MODE
DellEMC(conf)#ip http vrf {management | <vrf-name>}
Verify Software Images Before Installation
To validate the software image on the ash drive, you can use the MD5 message-digest algorithm or SHA256 Secure Hash Algorithm, after
the image is transferred to the system but before the image is installed. The validation calculates a hash value of the downloaded image le
on system’s ash drive, and, optionally, compares it to a Dell EMC Networking published hash for that le.
The MD5 or SHA256 hash provides a method of validating that you have downloaded the original software. Calculating the hash on the
local image le and comparing the result to the hash published for that le on iSupport provides a high level of condence 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, prevents the installation of corrupted or modied images.
The verify {md5 | sha256} command calculates and displays the hash of any le on the specied local ash drive. You can
compare the displayed hash against the appropriate hash published on iSupport. Optionally, you can include the published hash in the
verify {md5 | sha256} command, which displays whether it matches the calculated hash of the indicated le.
To validate a software image:
1 Download Dell EMC Networking OS software image le from the iSupport page to the local (FTP or TFTP) server. The published hash
for that le displays next to the software image le on the iSupport page.
2 Go on to the Dell EMC Networking system and copy the software image to the ash 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.
To validate the software image on the ash drive after the image is transferred to the system, but before you install the image, use the
verify {md5 | sha256} [ flash://]img-file [hash-value] command in EXEC mode.
• md5: MD5 message-digest algorithm
• sha256: SHA256 Secure Hash Algorithm
• flash: (Optional) Species the ash drive. The default uses the ash drive. You can enter the image le name.
• hash-value: (Optional). Specify the relevant hash published on iSupport.
• img-file: Enter the name of the Dell EMC Networking software image le to validate
Examples: Without Entering the Hash Value for Verication
MD5
DellEMC# verify md5 flash:file-name
