Scenarios and Migration Results
We recommend that
you migrate your legacy IP Device Tracking (IPDT) and IPv6 Snooping CLI
configuration to the new device-tracking CLI commands, using the
Based on the legacy
configuration that exists on your device , the
upgrade-cli command upgrades your CLI differently. Consider the following
scenarios and the corresponding migration information before you migrate your
Only IPDT Configuration
If your device has
only IP Device Tracking (IPDT) configuration, running the
upgrade-cli command internally translates the configuration to use the new
SISF policy that is created and attached to the interface. You can then update
this SISF policy.
Only IPv6 Snooping
On a device with
existing IPv6 Snooping configuration, the old IPv6 Snooping commands are
available for further configuration. The following options are available:
(Recommended) Use the device-tracking upgrade-cli command to migrate all your legacy configuration to the new SISF-based device-tracking commands. After all the legacy commands have been converted, only the new device-tracking commands will work on your device.
Use the legacy IPv6 Snooping commands for your future configuration and do not run the device-tracking upgrade-cli command. With this option, only the legacy IPv6 Snooping commands are available on your device, and you cannot use the new SISF-based device-tracking CLI commands.
policy named Default is created by the conversion process. You cannot manually
attach this policy to other interfaces.
Both IPDT and IPv6 Snooping
On a device that has both legacy IPDT configuration and IPv6 Snooping configuration, use the device-tracking upgrade-cli command to convert legacy commands to the new device-tracking CLI commands. However, note that only one snooping policy can be attached to an interface, and the IPv6 Snooping policy parameters override the IPDT settings.
If you do not migrate to the new SISF-based commands and continue to use the legacy IPv6 Snooping or IPDT commands, your IPv4 device tracking configuration information may be displayed in the IPv6 Snooping commands, as the unified feature handles both IPv4 and IPv6 configurations. To avoid this, we recommend that you migrate your legacy configuration to use the new device-tracking commands.
No IPDT or IPv6 Snooping
If your device has
no legacy IP Device Tracking or IPv6 Snooping configurations, you can use only
the new SISF-based
device-tracking commands for all your future configuration.
The legacy IPDT commands and IPv6 Snooping commands are not available.
