Which of the following is true of Cisco FabricPath edge ports?
- They allow only FabricPath VLAN traffic.
- The can be configured only as trunk ports.
- The encapsulate Ethernet frames in a FabricPath header.
- They are classic Ethernet ports.
Cisco FabricPath edge ports are classic Ethernet ports. Cisco FabricPath uses Open Systems Interconnection (OSI) networking model Layer 3 routing combined with Layer 2 switching to construct a unified and scalable Layer 2 fabric. An edge port is a Cisco FabricPath component port that does not operate as part of the FabricPath network.
Cisco FabricPath edge ports can be configured either as Institute of Electrical and Electronics Engineers (IEEE) 802.1Q trunk ports or as access ports. Trunk ports enable switches to transmit and receive data on multiple virtual local area networks (VLANs) over the same link. In a Cisco FabricPath network, core ports can be configured only as trunk ports. Core ports are ports that operate as part of the FabricPath network.
Cisco FabricPath core ports, not edge ports, allow only FabricPath VLAN traffic. Edge ports or normal trunk ports can carry classic Ethernet VLAN traffic. In addition, core ports encapsulate Ethernet frames in a FabricPath header because core ports operate as part of the FabricPath network. Edge ports carry classic Ethernet traffic and do not need to encapsulate that traffic in FabricPath headers.
