LACP Link Aggregation Control Protocol (LACP) provides a method to control the

bundling of several physical ports together to form a single logical channel.

LACP allows a network device to negotiate an automatic bundling of links by

sending LACP packets to the peer (directly connected device that also imple-

ments LACP).

LDAP The Lightweight Directory Access Protocol is an application protocol for

reading and editing directories 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.

LLDP Link Layer Discovery Protocol (LLDP) is an industry standard protocol

designed to supplant proprietary Link-Layer protocols such as Extreme's EDP

(Extreme Discovery Protocol) and CDP (Cisco Discovery Protocol). The goal

of LLDP is to provide an inter-vendor compatible mechanism to deliver Link-

Layer notifications to adjacent network devices.

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.

PFC/FC Priority Based Flow Control applies pause functionality to traffic classes OR

classes of service on the Ethernet link.

QoS or Quality of Service Quality of service is the ability to manage different applications or users by

priority such that a required bit rate, delay, packet dropping probability, and/or

other measures may be guaranteed.

QSFP_AMBIENT_TEMP Ambient temperature sensor of the QSFP cage for the selected Leaf or Spine

module

RADIUS Remote Authentication Dial In User Service. A networking protocol that

enables AAA centralized management for computers to connect and use a net-

work service.

RDMA (Remote Direct Memory

Access)

Accessing memory in a remote side without involvement of the remote CPU.

RSTP Rapid Spanning Tree Protocol. A spanning-tree protocol used to prevent loops

in bridge configurations. RSTP is not aware of VLANs and blocks ports at the

physical level.

SA (Subnet Administrator) 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.
