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.
Analyzing and
reporting
A process that captures metrics and packets.
Ansible A simple agentless automation framework. It can configure systems, deploy software, and orchestrate
advanced IT tasks such as continuous deployments and zero downtime rolling updates. Ansible supports
network automation as part of its core framework.
Anycast address A unicast address configured on more than one Rendezvous Point (RP). A packet sent to the anycast
address is sent to the nearest RP with anycast address, as determined by the routing protocol.
Anycast RP An implementation strategy that provides load sharing and redundancy in Protocol Independent Multicast
sparse mode (PIM-SM) networks.
Authentication,
Authorization,
and Accounting
(AAA)
A standard framework that controls user access to the switch (authentication), user operations
authorized on the switch (authorization), and history of user actions performed during a session
(accounting).
Auto An unauthorized state in 802.1x, in which a device connected to a port is subject to the authorization
process. If the process is successful, the port is authorized and the connected device communicates on
the network.
Automated
switch
provisioning
An automated process that enables configuration and monitoring using RESTCONF APIs, Linux DevOps
ecosystem, and Ansible.
B
Batch Mode
A mode the enables you to run a batch file with multiple commands.
BFD three-way
handshake
A process that exchanges synchronization and acknowledgment messages before the real data
communication process begins. BFD session requires a three-way handshake between neighboring
routers.
BGP
communities
A set of routes with one or more common attributes that are used in dynamic routing policies.
Bidirectional
Forwarding
Detection (BFD)
A protocol that provides rapid failure detection in links with adjacent routers.
Border Gateway
Protocol (BGP)
An external gateway protocol that transmits inter-domain routing information within and between
autonomous systems.
