Overview

AAA

Authentication, Authorization, and Accounting:

• Authentication—verifies user credentials (username and password).

• Authorization—grants or refuses privileges to a user/client for accessing specific services.

• Accounting—tracks network resources consumption by users.

ARP

Address Resolution Protocol. A protocol that translates IP addresses into MAC addresses for communication over a local area network (LAN).

CLI

Command Line Interface. A user interface in which you type commands at the prompt

DHCP

The Dynamic Host Configuration Protocol (DHCP) is an automatic configuration protocol used on IP networks.

DNS

Domain Name System. A hierarchical naming system for devices in a computer network.

Fabric management

The use of a set of tools (APIs) to configure, discover, and manage and a group of devices organized as a connected fabric.

FTP/TFTP/sFTP

File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the Internet.

Gateway

A network node that interfaces with both InfiniBand and Ethernet, using different network protocols

GID

Global Identifier. A 128-bit number used to identify a Port on a network adapter (see below), a port on a Router, or a Multicast Group.

GUID

Globally Unique Identifier. A 64-bit number that uniquely identifies a device or component in a subnet.

HA

High Availability. A system design protocol that provides redundancy of system components, thus enables overcoming single or multiple failures in minimal downtime.

Host

A computer platform executing an Operating System which may control one or more network adapters

IB

InfiniBand

LDAP

The Lightweight Directory Access Protocol is an industry standard application protocol for accessing and maintaining distributed directory information services over an IP network.

LID

Local Identifier. A 16 bit address assigned to end nodes by the subnet manager. Each LID is unique within its subnet.

MAC

A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used for numerous network technologies and most IEEE 802 network technologies including Ethernet.

MTU

Maximum Transfer Unit. The maximum size of a packet payload (not including headers) that can be sent /received from a port.

Network Adapter

A hardware device that allows for communication between computers in a network.

RADIUS

Remote Authentication Dial In User Service. A networking protocol that enables AAA centralized management for computers to connect and use a network service.

SA

Subnet Administrator (SA) is the interface for querying and manipulating subnet management data.

SCP

Secure Copy or SCP is a means of securely transferring computer files between a local and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol.

SNMP

Simple Network Management Protocol. A network protocol for the management of a network and the monitoring of network devices and their functions.

SOL

Serial Over LAN

NTP

Network Time Protocol. A protocol for synchronizing computer clocks in a network.

SSH

Secure Shell. A protocol (program) for securely logging in to and running programs on remote machines across a network. The program authenticates access to the remote machine and encrypts the transferred information through the connection.

syslog

A standard for forwarding log messages in an IP network.

TACACS+

Terminal Access Controller Access-Control System Plus. A networking protocol that enables access to a network of devices via one or more centralized servers. TACACS+ provides separate AAA services.
