Device types and versions are specified in a Device Type Version Capabilities (DTVC) file, which is an encrypted tar.gz file.
The DTVC file contains all the device type and version information that Visibility Manager needs to manage the related devices. DTVC files
for supported devices are included in the xvm-<version-build>.tar file
from which you extracted the installation files. For more information, see the
Extreme Visibility Manager Deployment Guide,
6.0.0
.
You can add a DTVC file at any time, and you are prompted to add a DTVC file when you log in to the interface for the first time. For more information, see Add a Device Type File.
Visibility Manager propagates the new device type and version information to its database and to all required microservices. Newly added devices are then verified against this collected information. Any device you add must match a device type and version in the database.
Each device type can support one or more device type versions and the capabilities of those versions. Capabilities are generally the features supported by a device.
You can delete a DTVC file, which also deletes the associated versions. This process requires you to remove devices that match the device type versions in the DTVC file you deleted.
