I have just restarted the VNA Spectrum landscape and after the restart every interface in the landscape has 2 alarms, PORT CONTACT LOST and PORT OPERATIONAL STATUS IS REPORTED AS DOWN.
Spectrum pulls the interface information from VNA and their plugin, in this case Viptela.
The AdminStatus and OperationalStatus are shown with null values from VNA.
Release : 20.2
Component : Virtual Network Assurance
VNA will add AdminStatus and OperationalStatus to the VNA inventory and should be released within the February 2021 end of month kit. Once VNA has been upgraded, Spectrum should provide only 1 alarm per interface.
