Which of the following FCoE switch port types is typically connected to a VE port?
- a VF port
- a SPAN port
- another VE port
- a VN port
A Fibre Channel over Ethernet (FCoE) virtual edge (VE) port is typically connected to another VE port. VE ports default to trunk mode and are used to create inter-switch links (ISLs) between Fibre Channel (FC) switches. Spanning Tree Protocol (STP) does not operate on VE ports because these ports typically connect two FC forwarders (FCFs). FC does not require switching loop prevention, because FCFs have no concept of switching loops.
FCoE is used in data centers to encapsulate FC over an Ethernet network. This encapsulation enables the FC protocol to communicate over 10 gigabit-per-second (Gbps) Ethernet. There are two types of FCoE switch ports: a virtual fabric (VF) port and a VE port.
An FCoE VE port typically connects to an end host. A virtual node (VN) port is a port on an end host, such as a host bus adapter (HBA) port. If the end host is connected to an Ethernet network that is configured with virtual local area networks (VLANs), the STP configuration on the Ethernet fabric might require extra attention, especially if the Ethernet fabric is not using Per-VLAN Spanning Tree Plus (PVST+). A proper STP configuration on the Ethernet fabric prevents the Ethernet topology from affecting storage area network (SAN) traffic.
A switched port analyzer (SPAN) port, which is also known as a mirroring port, is a type of port that is used to collect copies of packets transmitted over another port, over a given device, or over a network. In an FCoE configuration, a SPAN destination port can be either an FC interface or an Ethernet interface. SPAN source ports, on the other hand, can be FC interfaces, virtual FC (vFC) interfaces, a virtual SAN (vSAN), a VLAN, an Ethernet interface, a port channel interface, or a SAN port channel interface.
