Re: what is the UCS FI mechanism that update vlan created on

There is no mechanism. VLANs are locally significant unless the FIs trunk them northbound. The easiest way to think of it is the FIs are a server themselves. In end host mode the FIs don't do northbound mac learning like a normal switch, only southbound to the blades. The northbound switches only know of the UCS VLANs based on the data plane, there is no control plane protocol like STP or VTP.
