Description (partial)

Symptom:
VMware vCenter is offline according to the Cisco APIC. The Cisco APIC is unable to push port groups into VMware vCenter. The leader Cisco APIC for VMware vCenter connections shows as disconnected. There are faults on the VMM domain related to incorrect credentials, but the credentials are actually correct. The same credentials can be used to log in to the VMware vCenter GUI successfully. The "administrator@vsphere.local" account does not work either, so permissions should not be a problem.

The /var/log/dme/log/svc_ifc_vmmmgr.bin.log log file on the leader APIC reports a traceback when trying to parse a compEpPD encap with error message "ERROR. exception in parsing base:Encap. Format=vlan-".
