1 About this guide The glossary provides a quick definition of the terms used in the OS10 user guide. This guide is intended for system administrators who are responsible for configuring and maintaining networks. Documentation Feedback Dell Technologies strives to provide accurate and comprehensive documentation and welcomes your suggestions and comments.
2 Glossary of Terms A Access Control List (ACL) A filter that controls network traffic by dropping or forwarding packets based on a set of configured rules. Access Port A port on a VTEP switch that connects to an end host and is a part of the overlay network. Address Resolution Protocol (ARP) A protocol that runs over Ethernet and enables end stations to learn the MAC addresses of neighbors on an IP network. Alerting A process that triggers problem reporting.
C Command Alias A shortcut for commonly-used commands. Configuration mode A mode that enables you to change the current running configuration. Control-plane policing A Quality of Service (QoS) mechanism that increases system security by protecting the route processor from unnecessary traffic and prioritizing important control plane and management traffic. Converged Enhanced Ethernet (CEE) A technology that uses DCBX specification v1.
Dynamic Host Configuration Protocol A protocol that provides information to dynamically assign IP addresses and other configuration parameters to network hosts based on policies. E Encapsulated Remote Port Monitoring (ERPM) A protocol that encapsulates traffic from the source port and forwards it to the destination port in another switch. Enhanced Transmission Selection (ETS) A transmission selection algorithm that increases preferred traffic class throughput during network congestion.
Force-authorized An authorized state in which a device connected to the port can communicate on the network without using the authentication process. Full-duplex A transmission mode where a device, such as a switch, can transmit and receive data simultaneously. G gRPC Network Management Interface agent (gNMI) A protocol that enables the telemetry agent to transmit pre-configured sensor groups data to the SmartFabric Director.
L Last Hop Router (LHR) The last router in the multicast path that is directly connected to the multicast receiver. Link Aggregation (LA) A method of grouping multiple physical interfaces into a single logical interface. Link Aggregation Control Protocol (LACP) A protocol that exchanges information between two systems and automatically establishes a link aggregation group (LAG) between them.
Multiprotocol BGP (MBGP) An extension to BGP that supports multiple address families—IPv4 and IPv6. MBGP carries multiple sets of unicast and multicast routes depending on the address family. N N_Port ID Virtualization (NPIV) A process that allows multiple N_Port IDs to share a single physical N_Port. Neighbor Discovery Protocol (NDP) A protocol that determines if neighboring IPv6 devices are reachable and receives the IPv6 addresses of IPv6 devices on local links.
P Performance monitoring A process that establishes baselines and defines triggers for detecting performance problems. PIM Shared Tree (RP Tree) A unidirectional multicast tree whose root node is the RP. When receivers want to join a multicast group, they send join messages along the shared tree towards the RP. PIM Shortest Path Tree (SPT) A shortest path that a multicast packet can take from source to receiver.
Rapid Per-VLAN Spanning-Tree (Rapid-PVST) A protocol that is a combination of rapid spanning-tree (RSTP) and per-VLAN spanning-tree plus (PVST+) for faster convergence and interoperability. Rapid SpanningTree Protocol (RSTP) A protocol that provides faster convergence and interoperability with devices that are configured with the Spanning-Tree Protocol (STP) and Multiple Spanning-Tree Protocol (MSTP).
SNMP agent The software component that is responsible for the launcher object and responds to queries, carries out requests and issues traps. SNMP manager A system that controls and monitors the activities of network hosts using SNMP. SNMP trap A message sent by an SNMP Agent to the SNMP manager indicating that an event has occurred on the host running the network resource. Software Defined An architecture that decouples the software (control plane) from the hardware (data plane).
V Virtual extensible A type of network virtualization overlay that encapsulates a tenant payload into IP UDP packets for LAN (VXLAN) transport across the IP underlay network. Virtual fabric (vfabric) A fabric that divides a physical fabric into logical fabrics. Virtual LANs (VLANs) A group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments.
X X.509v3 certificates Certificates that secure communications between the switch and a host, such as a RADIUS server. Z Zero Touch Deployment (ZTD) A process that automates switch deployment and upgrades an existing OS10 image. It executes a CLI batch file to configure the switch, and executes a post-ZTD script to perform additional functions.
