FCoE switch—The switch supporting the FCoE protocol.
FCoE—Fiber Channel over Ethernet (FCoE) is a protocol that carries FC over Ethernet. It can provide
services for LANs and use SANs for storage simultaneously. In an FCoE solution, the server uses an
FCoE-capable Ethernet adapter, and the FCoE switch (FCoE forwarder) integrates the function of both
traditional IP switch and FC switch to realize I/O Consolidation. FCoE reduces the number of network
adapters, switches, and cables, and the network operation and maintenance workload.
Global DCBX Parameter—Global DCBX parameters take effect on all devices in VFM.
HBA—Host bus adapter (HBA) is an FC storage network card.
Inactive zone set—In a VSAN, there is only one active zone set and other zone sets are inactive. zones
in an inactive zone set cannot control access to N_Ports of servers or storage devices.
Ingress RB—An ingress RB is the node through which a frame enters the TRILL network.
Interface DCBX parameter—The DCBX parameter which takes effect on the interface in VFM.
I-SID—The backbone service instance identifier is the unique number of a VSI. In a single BEB device,
the I-SID indicates the number of the VSI. In an SPBN network, the I-SID indicates the number of an SPB
service.
LSDB—A link state database (LSDB) contains all link state information in the SPB or TRILL network.
LSPDU—A link state data unit (LSPDU) describes local link state information and is advertised between
neighbor devices.
N mode/N_Port—All ports on nodes (servers and storage devices) are in N mode. Port in N mode is
called N_Port. Ports in N mode include N_Ports and NL_Ports. An N_Port directly connects to a fabric.
An NL_Port connects to a fabric through an arbitrated loop.
NP mode/NP_Port—In a SAN network, a port is called NP_Port when it is operating in NP mode. An
NP_Port connects to the F_Port of another switch.
NPV mode—When an FCoE switch is operating in NPV mode, it can connect to the N_Port on a node
(a server or a storage device) through its F_Port or to the F_Port on an FCF switch through its NP_Port.
NPV switch—An FCoE switch is an NPV switch when it is operating in NPV mode. Its VFC interfaces
support F mode (F_Port) and NP mode (NP_Port).
Port mode—In a switched fabric, servers, storage devices, and FC switches communicate with each
other through ports of different modes. Ports of servers and storage devices are in N mode. Ports of FC
switches are in E mode, F mode, NP mode, or Auto mode.
RB—A routing bridge (RB) is a device that runs TRILL. RBs are classified into ingress RBs, transit RBs, and
egress RBs, depending on their position in the TRILL network. A frame enters the TRILL network through
an ingress RB, travels along transit RBs, and leaves the TRILL network through an egress RB.
SAN—Storage area networks (SAT) enable the universal connectivity of servers, network devices, and
storage devices and allow the servers to store, access, and back up data of high storage scalability and
availability. Servers connect to the storage devices and read or write data through the network devices.
SPB device—An SPB device is a network device (typically a switch) that supports the SPB technology.
SPB devices include backbone edge bridges (BEBs) and backbone core bridges (BCBs).
SPBM—Shortest Path Bridging MAC Mode (SPBM) is a bridging method of IEEE 802.1aq SPB. It
encapsulates Ethernet frames into MAC-in-MAC frames and forwards them in compliance with IEEE
802.1ah PBB.
SPBN—In VFM, SPBN is a network implementing the SPBM protocol, also called an SPBM network.
From the perspective of a user, SPBN is a Layer 2 switching network through which Layer 2 connection
