We've onboarded CISCO ACI devices via VNA plugin in NetOps Performance Management. But if we select any of the leaf or spine in Spectrum we are getting all interfaces in unreachable state.
Release : 21.2.x / 22.2.x
Spectrum with VNA integrated
Devices must be discovered with SNMP in Spectrum first
If the devices are snmp reachable then Spectrum must discover those switches using snmp
Also be sure that the required SNMP Community is set under the Spectrum VNM Model, Information tab -> Auto Discovery control -> protocol tables -> community strings
Once the community string is added, disable the VNA integration - wipes out all sdn based models and then reenable it.
All the switches must get discovered as snmp devices. In case if they are already discovered through snmp then they will get reconciled too.
