Known Affected Releases

11.4(0.137)

Description (partial)

Symptom:
During the brownfield migration in the Cisco DCNM Release 11.1(1), the overlay configuration profiles are deployed to switches and all the overlay related configurations are captured in the respective network or VRF freeform configs. Post migration, switches have both the original configuration CLIs and the config-profiles. This is ter"double intent".

From Cisco DCNM Release 11.2(1), during the brownfield migration, the overlay config-profiles are deployed to the switches, and the original configuration CLIs are automatically removed as part of the import process. Post migration, the switches only have the configuration profiles and any extra configuration that is not part of the configuration profile.
This behavior occurs only if the switches in the brownfield migration have the following Cisco NX-OS images:
* Cisco NX-OS Release 7.0(3)I7(6) or newer
* Cisco NX-OS Release 9.2(3) or newer

If the switches do not meet these requirements, the brownfield migration behavior is the same as described for the Cisco DCNM Release 11.1(1).

Having double intent will cause issues when overlay parameters are updated. Both the config profiles and the intent in the freeforms must be consistent.

Conditions:
The double intent for the overlay VRFs and Networks occurs under the following conditions:
* Brownfield migration is done in DCNM 11.1 irrespective of the NXOS image versions
* Brownfield migration is done in DCNM 11.2 and newer and NXOS image versions do not meet these requirements:
     - Cisco NX-OS Release 7.0(3)I7(6) and newer
     - Cisco NX-OS Release 9.2(3) and newer
