Rev 1.6.9 Table 4 - Glossary Term Description HA (High Availability) A system design protocol that provides redundancy of system components, thus enables overcoming single or multiple failures in minimal downtime. IB InfiniBand. LACP LDAP LID (Local IDentifier) 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 implements LACP). The Lightweight Directory Access Protocol is an application protocol for reading and editing directories over an IP network. 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 LinkLayer 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 QoS or Quality of Service Priority Based Flow Control applies pause functionality to traffic classes OR classes of service on the Ethernet link. 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 network service. RDMA (Remote Direct Memory Accessing memory in a remote side without involvement of the remote CPU. Access) 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. Mellanox Technologies 16 Mellanox® Technologies Confidential
