I have a Cisco APIC fabric with one ACI controller, two leaf swethes and one spine switch with version 3.2 (1m). And I decided to upgrade my fabric and now I have a 4.1(1j) version. I successfully upgraded APIC fabric but now from the APIC CLI I can not ping the vCenter server. Although before upgrading I can ping this server.Also, I can not integrate Cisco ACI with vCenter, I see the next fault: "Add-FSM for VM Controller: vCenter VM Domain: Stand-vCenter VM Provider VMware Error: Failed to retrieve ServieceContent from the vCenter server 10.1.1.1". I have the vCenter Server version 6.7 and ESXi version 6.5
Maybe this issue connected with new soft version and ACI do not supported vCenter? Although, I see the next matrix https://www.cisco.com/c/dam/en/us/td/docs/Website/datacenter/aci/virtualization/matrix/virtmatrix.html and everything is ok.
