Cisco Enterprise Network Function Virtualization Infrastructure Software Configuration Guide, Release 3.5.1

The Cisco Enterprise NFVIS upgrade image is available as a .nfvispkg file. Currently, downgrade is not supported. All RPM packages in the Cisco Enterprise NFVIS upgrade image are signed to ensure cryptographic integrity and authenticity. In addition, all RPM packages are verified during Cisco Enterprise NFVIS upgrade. For more information about the Image Signing and Verification feature, see Image Signing and Verification.

Ensure that you copy the image to the Cisco Enterprise NFVIS server before starting the upgrade process. Always specify the exact path of the image when registering the image. Use the scp command to copy the upgrade image from a remote server to your Cisco Enterprise NFVIS server. When using the scp command, you must copy the image to the "/data/intdatastore/uploads" folder on the Cisco Enterprise NFVIS server. The following is an example on how to use the scp command to copy the upgrade image:


scp -P 22222 nfvis-351.nfvispkg admin@192.0.2.9:
/data/intdatastore/uploads/nfvis-351.nfvispkg

Alternatively, you can upload the image to the Cisco Enterprise NFVIS server using the System Upgrade option from the Cisco Enterprise NFVIS portal.

The upgrade process comprises two tasks:

  • Registering the image using the system upgrade image-name command.

  • Upgrading the image using the system upgrade apply-image command.

Registering an Image

To register an image:


configure terminal
system upgrade image-name nfvis-351.nfvispkg location /data/intdatastore/uploads
commit


Note

You must verify the image registration status before upgrading the image using the system upgrade apply-image command. The package status must be valid for the registered image.


Verifying the Image Registration

Use the show system upgrade reg-info command in the privileged EXEC mode to verify the image registration.


nfvis# show system upgrade reg-info                  
PACKAGE 
NAME             LOCATION                               VERSION        STATUS UPLOAD DATE

Upgrading the Registered Image

To upgrade the registered image:


configure terminal
system upgrade apply-image nfvis-351.nfvispkg scheduled-time 5
commit

Verifying the Upgrade Status

Use the show system upgrade apply-image command in the privileged EXEC mode


nfvis# show system upgrade apply-image
