BPDU Bridge Protocol Data Unit: A spanning tree configuration frame
exchanged between switches in the same spanning tree domain
CDP Cisco Discovery Protocol: A proprietary Cisco protocol used to exchange
neighbor information between two directly connected Cisco devices
CX-4 An industry standard cabling specification used by VC for network
connectivity using 10 Gbit Ethernet over copper.
DCBX DCBX is a discovery and capability exchange protocol to
discover peers and exchange configuration information
between DCB–compliant bridges.
ETS Enhanced transmission selection (ETS; IEEE 802.1 Qaz) Enables bandwidth
management between traffic types for multiprotocol links.
External Network The network and associated network devices external to the VC domain
FCOE Fibre Channel Over Ethernet – Fibre Channel frames are encapsulated in a
Ethernet Frame and transported over the Ethernet network.
Internal cross-connect A non-visible port that interconnects two horizontally adjacent VC-Enet
Modules – used for updating the Virtual Connect Managers on each of the
Virtual Connect Modules.
LACP Link Aggregation Control Protocol: An 802.1ax Link Aggregation
configuration frame exchanged between two devices that form a port
trunk\channel between them. This was originally part of the 802.3AD
specification but was moved to the 802.ax – 2008 specification.
LAG Link Aggregation Group. 802.1ax terminology for a port trunk\channel
group
LLDP Link Layer Discovery Protocol. An IEEE protocol that provides CDP-like
functionality
Logical Path A single physical port or a single port channel. Both represent a single
communication path.
LOM LAN on Motherboard. A NIC embedded on the system board of a
server.
Oneview HP’s new Server Management platform.
PFC Priority-based Flow control (PFC; IEEE 802.1 Qbb) Provides capability to manage
bursty, single traffic source on a multiprotocol link.
Port Trunk (channel group) A group of two or more ports that operate as a single logical port and
single logical path for the purposes of load balancing. 802.3ad and
EtherChannel are both port trunking technologies
Quality of Service (QoS) A very broad term associated with network traffic classification,
prioritization, queuing, marking, etc. Quality of service is particularly important
for the transport of traffic with special requirements. In particular, much
technology has been developed to allow computer networks to become as useful
as telephone networks for audio conversations, as well as supporting new
applications with even stricter service demands.
Server Profile An object within the Virtual Connect domain that is assigned to a server bay
