Acronym or Abbreviation
Expansion and Description
AMQP
Advanced Message Queuing Protocol
AMQP is a message bus architecture protocol for communication with exter
nal components. Cisco Prime™ Data
Center Network Manager (DCNM) includes a built-in AMQP server and uses this protocol to send and receive
northbound AMQP notifications to the orchestration layer to create, update, delete, etc. workload-automation
profiles. All organization, partition, network create/delete/update etc. events received by the DCNM via REST APIs
are published to a queue on the AMQP server. In this way, external entities can subscribe to these events and
consume selected ones on a need basis. An example includes the Cisco Prime Network Services Controller (NSC)
for seamless services integration with the Cisco Unified Fabric.

Anchor leaf
Specific functionality of a Physical Switch in an Optimized Network Fabric; Coexists with or uses Migration
mode with Cisco FabricPath
mode with Cisco FabricPath
An anchor leaf node provides the Layer 3 first-hop gateway for Layer 2-only Cisco FabricPath server leaf switches.
Optionally, a border leaf switch can function as an anchor leaf.

ARP
Address Resolution Protocol
ARP is a protocol mainly used on end-host devices to learn the MAC address for a given IP address. Depending of
the configuration of distributed gateway feature integrated into the Cisco Unified Fabric on the leaf, the leaf switch
responds to the ARP request locally, or the ARP request is flooded across the Cisco Unified Fabric. ARP packets
can be used to detect and track IPv4 end-hosts in conjunction with the Host Mobility Manager (HMM) and trigger
end-host profile instantiation.

BFD
Bidirectional Forwarding Detection
BFD is a lightweight protocol designed to quickly detect failures in the path between two adjacent nodes. In the
data center fabric, BFD is used with Cisco FabricPath Intermediate System-to-Intermediate System (IS-IS) protocol.
Configuration of BFD on Cisco FabricPath IS-IS links with back-to-back dark fibers can provide an additional
safeguard to detect failures not signaled over Layer 1, such as upper protocol software failures or unidirectional link
failures.

BiDi
Bidirectional; refers to Cisco QSFP 40-Gbps Bidirectional Transceiver
The 40-Gbps BiDi optical module supports 40 Gigabit Ethernet over one pair of multimode fiber (MMF) cables with
LC connectors while allowing 40 Gigabit Ethernet to be deployed using the same infrastructure as 10 Gigabit
Ethernet (10GBASE-SR). This innovative Cisco 40-Gbps QSFP BiDi technology offers customers no-cost fiber
migration from 10 Gbps to 40 Gbps.

Border leaf
Specific Role of a Physical Switch in an Optimized Network Fabric
A border leaf node typically is a node with connections outside the Cisco Unified Fabric: for example, the
attachments of the data center interconnect (DCI) or connectivity to the enterprise network or WAN.

CPOM
Central Point of Management
Please see the information provided for DCNM.
DCI
Data Center Interconnect
DCI refers to a connection between two or more data centers. It typically provides Layer 2 connectivity. Overlay
Transport Virtualization (OTV) and Virtual Private LAN Services (VPLS) typically are considered to be Layer 2 DCI
technologies. The attachment point of the DCI is the border leaf. In addition, workload mobility is provided through
the enhanced forwarding capabilities of the distributed gateway over a Layer 3 DCI connection between the border
leaf switches.

DCNM
Data Center Network Manager; refers to Cisco Prime Data Center Network Manager
Cisco Prime DCNM is designed to help network administrators efficiently implement, visualize, and manage Cisco
Unified Fabric. It includes a comprehensive feature set and a customizable dashboard that provides enhanced
visibility. It provides a ready-to-use day-1 switch deployment solution through Power-On Auto-Provisioning (POAP)
and automated workload fabric provisioning for end-hosts with autoconfiguration templates. It also provides
enhanced fabric management capabilities for both LAN and SAN services while also bundling a DHCP server, tftp
server, XMPP server, and a LDAP server. Cisco Prime DCNM often is described as a common point of
management (CPOM).
