DRB A designated routing bridge (DRB) is similar to the designated DIS in IS-IS. It helps simplify the
network topology, and appoints AVFs and appointed ports for the VLANs on each RB in the
broadcast network.
E
E mode/E_Port In a SAN network, a port is called E_Port when it is operating in E mode. An E_Port connects to
the E_Port of another switch.
ECT The equal cost tree (ECT) is the best forwarding path generated from one device to another in
an SPBN network. ECT is generated by the shortest path first (SPF) and ECT algorithms based on
the LSDB.
ECT Migration ECT migration refers to the process that the SPB service migrates from one ECT algorithm to
another with minimum traffic loss.
ED An edge device (ED) is the switch device at the DC edge to provide Layer 2 interconnection
between DCs.
Egress RB An egress RB is the node where a frame leaves the TRILL network.
ENDC The EVI neighbor discovery client (ENDC) works with an ENDS to learn neighbor information
and triggers EVI link setup between neighbors.
ENDP The EVI Neighbor Discovery Protocol (ENDP) uses the client/server model to dynamically discover
sites and edge devices, and to establish and maintain EVI links in an EVI network.
ENDS The EVI neighbor discovery server (ENDS) uses ENDP to maintain all neighbor information (such
as IP address) in an EVI network.
EVI Ethernet Virtual Interconnect (EVI), is a MAC-in-IP technology that provides Layer 2 connectivity
between distant Layer 2 network sites across an IP routed network. It is used for connecting
geographically dispersed sites of a virtualized large-scale data center that requires Layer 2
adjacency. EVI maintains MAC routing information on the edge devices without changing the
forwarding or routing information within the sites or the IP network.
EVI device An EVI device is the network device (typically a switch) that supports the EVI technology.
EVI link An EVI link is a bidirectional virtual Ethernet channel between a pair of edge devices in an EVI
network. Data in DCs are conveyed on EVI channels. Each EVI link is uniquely identified by an
EVI-Link interface and IP address of the remote edge device.
EVI network An EVI network is a virtual network established among edge devices in a data center to provide
Layer 2 interconnection among DCs. Through an EVI network, DCs advertises each other the
MAC addresses of all hosts and devices that are connected to edge devices, and forward frames
in a large area at Layer 2.
F
F mode/F_Port In a SAN network, a port is called F_Port when it is operating in F mode. An F_Port connects to
an N_Port or an NP_Port of another FC switch.
Fabric In VFM, a fabric includes FCoE switches, servers, and storage devices and transmits data for
servers and storage devices. When setting up a fabric, you must assign a domain ID to each FC
switch in the fabric and assign an FC address to each node connected to the fabric.
FCF mode When an FCoE switch is operating in FCF mode, it can connect to the E_Port on another FCF
switch through its E_Port, or connect to the N_Port on a node or the NP_Port on an NPV switch
through its F_Port.
FCF switch An FCF switch is an FCoE switch that is operating in FCF mode. Its VFC interfaces support E mode
(E_Port) and F mode (F_Port). VFM manages FCF switches.
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.
FCoE switch The switch supporting the FCoE protocol.
