Note Classical Ethernet is referred to as CE in this document. ![]() When the frame leaves the FabricPath network to go to a CE network, the egressing interface decapsulates the frame and leaves the regular CE header. The system builds paths, called trees, through the FabricPath network and assigns a forwarding tag (FTag) by flow to all the traffic in the FabricPath network. When a frame enters the FabricPath network from a Classical Ethernet (CE) network, the ingressing interfaces encapsulate the frame with a FabricPath header. The system randomly assigns a unique switch ID to each device that is enabled with FabricPath. Enhances mobility and virtualization in the FabricPath network.Provides a single control plane for unknown unicast, unicast, broadcast, and multicast traffic. ![]() Provides built-in loop prevention and mitigation with no need to use the Spanning Tree Protocol (STP).Allows Layer 2 multipathing in the FabricPath network.Note You must have an F Series module installed in your Nexus 7000 Series chassis in order to run FabricPath and conversational learning.īeginning with the Cisco NX-OS Release 5.1 and when you use an F Series module, you can use the FabricPath feature.
