Campus Fabric (SPX) Image Upgrade

Any unit that is part of a Campus Fabric domain is automatically updated with the correct image if an image mismatch within the same major version occurs.
Note: A PE candidate can be discovered and added to the Campus Fabric Domain by the zero-touch or the SPX interactive-setup utility; however, because Campus Fabric requires a router image, the new device will initially be in a non-operational state due to an image mismatch. If tftp-server is configured and image-auto-copy is not disabled, the CB will download a router image to a non-operational PE unit. The PE reloads, joins the Campus Fabric domain, and becomes operational.
Note: If the CB and PE are running different major release versions, for example, FastIron 08.0.30 and FastIron 08.0.40, then the auto image copy process cannot copy the image.

When an image mismatch occurs in a traditional stack, the active controller (master unit) copies its own image to the mismatched units. As part of a CB stack, CB units can be updated in the same way. However, in a Campus Fabric domain, the CB and PE require different images. In addition, the PE image cannot be stored on an ICX 7650, ICX 7750, or ICX 7850 stack unit.

Verify previous statement.

To copy the image of a PE in a Campus Fabric domain, the auto image copy process accesses the correct PE image on a TFTP server. If the correct image is found on the server, it is downloaded to the mismatched unit. Once the correct image has been copied, the mismatched unit is reloaded to activate the new image. If more than one PE unit is being updated, all mismatched units are reloaded at the same time. When the auto image copy process is complete, all units are up to date and available.

Commands are provided to configure the TFTP server. If no TFTP server has been configured when a mismatch occurs, you are prompted to provide the IP address for the server. If the server cannot be reached or if the correct image cannot be found on the TFTP server, the system checks for any attached USB drive and updates the mismatched PE unit or units if a PE image is found. Otherwise, the unit or units remain in an image mismatch state until you manually copy the image from an external server.

Auto Image Copy Considerations

  • The process does not execute if the running image and corresponding flash image are not the same.
  • The process is not triggered if the major versions of the mismatched units are not the same.
  • The process may run more than once if stack units are placed in nonoperational mode at different times.

In this section:

  1. Disabling or Re-enabling the Auto Image Copy Process for a Campus Fabric (SPX) Configuration
    The auto image copy process is enabled by default but may be disabled.
  2. Configuring a TFTP Server for Campus Fabric (SPX) auto image copy
    You can designate a TFTP server from which the auto image copy process downloads the correct PE image to a mismatched unit.
  3. Manual Upgrade of Campus Fabric (SPX) Images Using a Manifest File
    Manifest files are prepared for every release. They contain and list all boot, firmware, and application images as well as signature files. A manifest file also specifies a relative directory path to the images.
