To reduce configuration errors and simplify administration, the switch distributes the configuration data to
all the connected adapters.
STP Lite
FCoE does not require full Spanning Tree Protocol (STP) because FCoE has no bridging functionality, which
means that no STP loops are created in the network. STP Lite on FCoE interfaces ensures rapid convergence
across the network by sending an agreement Bridge Protocol Data Unit (BPDU) whenever it receives a proposal
BPDU. The FCoE link sends the identical agreement BPDU in response to either an Multiple Spanning Tree
(MST) or a Per VLAN Rapid Spanning Tree Plus (PVRST+) proposal BPDU. Additionally, STP Lite suppresses
the MAC address flushing function for FCoE VLANs.
STP Lite is enabled automatically by default across the entire device for FCoE VLANs as soon as the first
FCoE VLAN comes up. At the same time, the system automatically converts all FCoE links as the STP-type
normal ports. This feature runs only in FCoE VLANs.

Licensing Requirements for FCoE
License
Product
Each F Series module that runs FCoE requires an
FCoE license. FCoE enabled in a nondefault VDC
does not require the Advanced Services License. For
a complete explanation of the Cisco NX-OS licensing
scheme and how to obtain and apply licenses, see the
Cisco NX-OS Licensing Guide.
