A
AC A physical or virtual attachment circuit (AC) connects a BEB to a user network.
Active zone set Zones in the active zone set of a VSAN control access to N_Ports of servers or storage devices.
There is only one active zone set in a VSAN.
Appointed port To avoid loops, TRILL requires all the traffic of a VLAN on a broadcast network to enter and leave
the TRILL network through the same port of an RB. The port is the appointed port.
AVF To avoid loops, TRILL requires all the traffic of a VLAN on a broadcast network to enter and leave
the TRILL network through the same port of an RB. The RB is the appointed VLAN-x forwarder
(AVF) of the VLAN, and the port is the appointed port.
B
AVF To avoid loops, TRILL requires all the traffic of a VLAN on a broadcast network to enter and leave
the TRILL network through the same port of an RB. The RB is the appointed VLAN-x forwarder
(AVF) of the VLAN, and the port is the appointed port.
B-VLAN BCBs forward MAC-in-MAC frames based on the B-MAC and B-VLAN in an SPBN network. BEBs
encapsulate customer frames with MAC addresses and VLANs assigned by the service provider.
MAC addresses and VLANs assigned by the service provider are backbone MAC addresses
(B-MACs) and backbone VLANs (B-VLANs).
BCB Backbone core bridges (BCB) are core nodes of an SPB network. They are identical to the provider
devices in an MPLS VPN network. BCBs forward MAC-in-MAC frames based on the B-MAC and
B-VLAN. They just forward the packets and do not learn customer MAC (C-MAC) addresses to
lower network deployment cost and provide better scalability for SPBN.
BEB Backbone edge bridges (BEB) are edge nodes of the SPBM network. They are identical to provider
edges (PEs) in an MPLS VPN network. BEBs encapsulate customer frames into MAC-in-MAC frames
before forwarding them to an SPBM network. BEBs also decapsulate MAC-in-MAC frames before
sending them to a customer site.
C
CEE Converged enhanced Ethernet, also known as date center Ethernet (DCE), is enhancement and
expansion of traditional Ethernet local area networks for use in data centers.
CEE interface A CEE interface is an Ethernet interface on which DCBX parameters are configured. CEE interfaces
are used to connect switches and servers and enable the switches to control server adapters for
forwarding consistency.
CSNP A Complete Sequence Number PDU (CSNP) records all LSP digests of the local LSDB. On a
broadcast TRILL network, the DRB advertises CSNPs at the CSNP interval to perform network-wide
LSDB synchronization.
D
DC A data center is a facility that houses data, provides services, and includes servers, network
devices, storage devices, and others. VFM manages DC networks and the network devices,
servers, storage devices in DCs.
DCBX The Data Center Bridging Exchange Protocol (DCBX), as part of CEE/DCE protocols, is used to
negotiate and remotely configure the bridge capability of network elements. DCBX applies to an
FCoE based data center network, and operates on an access switch. DCBX enables the switch
to control the server adapter, and simplifies the configuration and guarantees configuration
consistency.
Distributing zones Distributing zones indicates that a device distributes its active zone set or zone database to all
the other devices in the same fabric. The distributing device is called a "manager switch," and
all the other devices are called "managed switches."
