350-601 Implementing and Operating Cisco Data Center Core Technologies (DCCOR) Vocabularies and URLs

Vocabularies:

NPIV – N-Port Identifier Virtualization, allows a Fibre Channel host connection or N-Port to be assigned multiple N-Port IDs or Fibre Channel IDs (FCID) over a single link.
FCID – Fibre Channel IDs
EPLD – electronic programmable logic device, image upgrades solution to enhance hardware functionality or to resolve known issues. EPLDs are hardware components such as ASICs on I/O modules that can be upgraded without having to replace the hardware. EPLD upgrades are typically not required, but in some cases, such as new chassis installs or chassis redeployments, we recommend that you upgrade to the latest EPLD version to ensure that all upgradable hardware components have the latest feature enhancements and caveat fixes
RPF – Reverse Path Forwarding, Reverse path forwarding (RPF) is a technique used in modern routers for the purposes of ensuring loop-free forwarding of multicast packets in multicast routing and to help prevent IP address spoofing in unicast routing.
RPF, unicast – Unicast RPF does a reverse lookup in the Cisco Express Forwarding table to check if any packet received at the interface of a device arrive
RPF, multicast – Reverse path forwarding (RPF) is a technique used in modern routers for the purposes of ensuring loop-free forwarding of multicast packets in multicast routing and to help prevent IP address spoofing in unicast routing.
LUN – logical unit number, is a slice or portion of a configured set of disks that is presentable to a host and mounted as a volume within the OS.
EPG – Endpoint Groups, ACI EPG provide a new model for mapping applications to the network.
VMM – Virtual Machine Manager, as in VMM Domain, A VMM domain enables VM mobility within the domain but not across domains.
APIC – Application Policy Infrastructure Controller, is the unifying point of automation and management for the Application Centric Infrastructure (ACI) fabric.
ACI – Application Centric Infrastructure, ACI makes application deployment simpler, faster and more efficient.
POAP – PowerOn Auto Provisioning as in NX-OS, automates the process of upgrading software images and installing configuration files on devices that are being deployed in the network for the first time.
HyperFlex – HyperFlex systems combine software-defined storage and data services software with Cisco UCS (unified computing system), a converged infrastructure system that integrates computing, networking and storage resources to increase efficiency and enable centralized management.
ISSU – In-Service Software Upgrade, a process that upgrades an image to another image on a device while the network continues to forward packets.
NFS – Network File Sharing, uses Kerberos-based security model
AAEP – Attachable Access Entity Profile (AEP for short) as in Cisco ACI Fabric, a construct of the ACI fabric that joins separate entity types. It is a critical policy object with associating a given domain type and VLAN pool with interface policy that will be used within tenant space.
CoPP – Control Plane Policing (CoPP) is the mechanism that allows us to policy the coming traffic to the Control Plane. Here, CoPP defines traffic classification, queue mapping and queue shaping for control plane packets. This protects Control Plane from malicious network attacks like DoS Attacks.
VNTag – Virtual Network Tag
FCoE – Firbre Channel over Ethernet
SMB – The Server Message Block protocol is a network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network. The SMB protocol can be used on top of its TCP/IP protocol or other network protocols.
WWPN – World Wide Pool Name, A WWPN pool is a WWN pool that contains only WW port names. If you include a pool of WWPNs in a service profile, the port on each vHBA of the associated
WWNN – World Wide Node Name
BFD – Bidirectional Fowarding, BFD is a detection protocol that you enable at the interface and routing protocol levels. Cisco supports the BFD asynchronous mode, which depends on the sending of BFD control packets between two systems to activate and maintain BFD neighbor sessions between routers.
