Description (partial)

Symptom:
Dynamic VLANs are programmed on interfaces that are not associated to the VLAN pool/AEP.  This behaviour is seen when a UCS Fabric Interconnect blade switch has multiple uplinks to the fabric. Although some of those uplinks are mapped to a different AEP and the is EPG set for pre-provision, dynamic EPGs still are reported for that EPG.

Conditions:
This issue occurs when a blade switch or 'unmanaged node' has multiple uplinks discovered through CDP/LLDP on different leaf switches, which are associated to different AEPs.
