This document describes the supported IPFIX functionality on platforms that make use of the SFE forwarding agent.

Arista CloudEOS provides optimized routing and security functionality by connecting different enterprise branches, DCs and head office across different geographical regions, zones and sites. It uses traffic engineering to leverage the best paths across a bunch of Dynamic Path Selection( DPS ) tunnels which are used to carry the overlay data traffic. It uses the concept of AVT( Adaptive Virtual Topology) to map any given VRF traffic into a specific subsets of traffic each of which is treated uniformly for the routing/security perspective.

Network Address Translation (NAT) is a feature used to obfuscate private internal addresses to the external world. The feature makes sure that private internal addresses are translated into a publicly visible address which is used by all external hosts and it also does the reverse translation of the public address to the private internal address.

Network Hierarchy transforms the way you monitor and manage your campus network by providing an aggregated view of metrics and telemetry across distinct network layers. With just a few clicks, you can drill down through the aggregated state of the network to individual interfaces, providing you with both high-level and granular perspectives of the network, device, and interface states.

Profiles are assigned to user accounts to customize their landing page on CloudVision and present information relevant to them. You can use built-in profiles or create custom ones. Profiles are assigned in Users to user accounts.

In a typical CloudVision-DMF integration deployment, CloudVision Portal (CVP) deploys alongside the DANZ Monitoring Fabric (DMF). The DMF Controller communicates with CVP to retrieve its managed device inventory and configures port mirroring sessions on any CVP-managed production devices that are Arista Extensible Operating System (EOS) switches.

Cluster Load Balancing is a feature designed to ensure optimal load balancing of flows used as part of GPU based cluster communication. When this feature is enabled, a TOR router monitors RoCE traffic flowing between the GPU servers and spine uplinks and ensures optimal load balancing in the network.

Cluster Load Balancing for Spine is a feature designed to ensure optimal load balancing of flows used as part of GPU based cluster communication in a network that uses multiple links to connect a TOR router to a Spine router.. When this feature is enabled on a Spine, it monitors RoCE traffic coming from a TOR and applies optimal load balancing when forwarding the traffic to the next TOR router hosting the destination GPU server.

Common Management Interface Specification (CMIS) defines, starting with revision 4.0, a standard mechanism for managing the firmware of compliant transceivers. This mechanism allows for transceivers’ firmware to be updated without having to remove the transceiver from the switch. Firmware updates may be necessary in a testing or production environment to resolve potential firmware bugs. Some transceivers may also support firmware management operations in a hitless manner (without impacting traffic).

Coherent signaling technology is used for data transmission over long distances. These transmitted signals are

Traditional policers treat all packets equally without considering the color of the incoming packet, potentially leading to transmission of excess packets that have already been marked with lower priority. Color aware flag in a policer configuration addresses this by providing the ability to consider the incoming packets’s drop precedence (DP) value while taking the policing decision on a given interface.

Command API's authentication can now be accomplished via X.509 public key certificates. Public key

Command API requests for "show" commands return structured outputs which are based on some internal models in EOS. In

CloudVision allows users to maintain multiple login sessions simultaneously. However, to prevent account sharing, administrators can now limit the number of active login sessions a user can have and terminate a user’s open sessions if that have reached their limit and are unable to log in.

Config checkpoint mechanism provides a shortcut to copy the current running config into a file stored in checkpoint

The Commit Timer mechanism provides a way to automatically rollback changes done by a config session, unless

In EOS 4.15.0F release, we have introduced the configuration sessions feature. Configuration sessions allow the

Under config router bgp mode, the following is the format for configuring remote port for a peer or peer grou

Currently when programming ECMP routes only one path is programmed in the kernel. There exists an environment variable (KERNELFIB_PROGRAM_ALL_ECMP) that allows users to program all paths from an ECMP route in the kernel. However, setting the variable requires restarting the KernelFib agent. This restart then reprograms all the routes.

An IPv6 link local address for an interface is generated automatically using the modified EUI 64 scheme. All IPv6

A DMF interface used by a DMF policy as both a filter and a delivery interface is known as a filter-and-delivery interface. Filter-and-delivery interfaces now support configuring sFlow in the DMF Controller.

Configurable TPID enables TPID to be configured per switchport (default TPID on switchport is 0x8100) on

On 7280R/R2, "Configurable TPID" enables a TPID to be configured per switchport (default TPID on switchport is 0x8100). A packet is considered tagged (both from ingress and egress point of view) on an interface if and only if TPID of the outermost VLAN tag on the packet matches the TPID configured on the interface.  Up to 3 distinct (non-default) TPID values may be recognized per chip.

Transmit queues are logical partitions of an Ethernet port’s egress bandwidth. Data streams are assigned to queues based on their traffic class, then sent as scheduled by port and transmit settings. Sand platform switches have eight queues, 0 through 7, and all queues are exposed through the CLI. However, queue 7 is not user-configurable. Queue 7 is always mapped to traffic class 7, which is reserved for control plane traffic. This feature allows tx-queue 7 to be configurable. As of 4.33.0F, a limited set of features are configurable on tx-queue 7.

Antenna gain measures an antenna's effectiveness in sending and receiving signals. It doesn’t amplify the total radio signal strength but redistributes the signal in the desired direction to maximize signal coverage, reduce interference, and enhance network performance.

Arista Access Points (AP) support configuring the Maximum Transmission Unit (MTU) to send large packets without fragmentation. The default MTU is 1500 bytes.

Connectivity Monitor is an EOS feature that allows users to monitor their network resources from their Arista switches. The resources being monitored may or may not be Arista devices. Connectivity monitoring is unidirectional in nature.

A new Connectivity Monitor panel allows users to easily view the health of device connections in Dashboards. The Connectivity Monitor panel displays EOS probes, categorizes connections as either Healthy or Unhealthy, and identifies the number of devices involved. By clicking on an Unhealthy connection, you can view the Connectivity Monitor events related to the connection.

This feature is an extension to the Explicit Congestion Notification (ECN) functionality for non ECN Capable

With the 12.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces the capability to copy policies from one Wireless Manager server and reuse it in another server.

With the 16.0 release, network administrators do not have to define the VLANs received from the RADIUS server or CoA servers. The RADIUS server can dynamically generate VLANS for clients and send the VLAN to the access point (AP) when the client connects. This eliminates the need to manually configure all the dynamic VLANS in the SSID and Device settings. When Dynamic VLAN is enabled, network administrators do not have to configure the VLANs in SSID Settings; they are created dynamically on the AP.

This feature supports configuring more than one L3 delivery interface over the same subnet using the same gateway.

The feature adds cross-VRF support for dynamic prefix-list.

Dynamic prefix-list policy construct is similar to the traditional IP and IPv6 prefix-list, except that they have an additional state associated. This state associated with the dynamic prefix-lists, is determined on the basis of the route entries in FIB, and hence as and when the FIB changes, the state also changes dynamically. This state determines the dynamic prefix-list behavior, when used in route-map/RCF match clauses or route injection.

Until the DMF release 8.9, DMF users had no direct visibility into the current scale against the verified scale across the DMF fabric. This feature exposes the current scale against the verified scale via REST APIs, GUI, and CLI commands. The verified scale represents the capacity tested under reference conditions.

This feature allows the configuration of custom DSCP-to-DSCP maps on a per-Nexthop Group (NHG) basis. When applied it rewrites the DSCP of the outer IPv4 header of IPvX-in-IPv4 (X represents both v4 and v6) encapsulated packets using the inner IPvX header’s DSCP value while ensuring the DSCP of the inner IPvX overlay is preserved.

This feature allows the user to define a custom COS To Traffic-Class (TC) and Drop-Precedence (DP) map and apply it to an interface.

This feature allows the user to define a custom COS To Traffic-Class (TC) profile and apply it to an interface.

This feature allows the user to define a custom DSCP-To-TC map and apply it to an interface.

The feature allows to create a custom (i.e. named) TC, DP to DSCP mapping profile that can be applied on an interface.
