In Spectrum release 10.3.x, when the VNA integration is disabled, all the devices modeled in VNA are deleted.


This happens because in Spectrum 10.3.x, when VNA integration is enabled, the models which existed before the integration are moved to VNA Container.
And when VNA integration is disabled, all VNA models are deleted.


Release : 10.3.x, 10.4.0

Component : Virtual Network Assurance For CA Spectrum


This is a known behavior in Spectrum 10.3.x and 10.4.0

A fix to retain all SNMP models in Spectrum after disabling VNA integration is included in Spectrum 10.4.1:
Symptom: When VNA Integration is enabled, the models which existed before integration are moving to VNA Container.

Resolution: Code changes are made to ensure that the models that existed before the VNA integration are not moved to VNA Container. (DE411730, 1329530, 10.4.1)

With this fix, the Spectrum models (SNMP models) will not be deleted after VNA integration is disabled.
All logical VNA models will be deleted after disabling the integration.

To avoid this problem in Spectrum 10.3.x and retain the models after disabling VNA integration, the following workaround can be used:

set the 'is_Existed_Model' attribute (0x133a9) to 'Yes' for all Spectrum models before disabling VNA integration.
