With the 12.0 release, you can view the criteria and parameters that influenced a channel change event. The data provides you insights on why the access point (AP) selected a particular channel over another.

With the DANZ Monitoring Fabric (DMF) 8.7 release, DMF Controller support for modular chassis switches has been improved by adding platform compatibility for DCS-7289-CH switches. DMF Controller and switch sync-up have also been improved to maintain state consistency.

With the 14.0 release, CV-CUE brings the ability to create checkpoints to save your current configurations, profiles, and settings. Creating and restoring a checkpoint is possible for all configuration settings available in CV-CUE. You can create a checkpoint for location based configurations, group configurations, or global configurations. For all the configurable settings that are available for a network, you can create a checkpoint to save it. 

This feature allows failover to the backup path to occur in constant time per interface going down for features such as RSVP link protection, RSVP node protection, TI-LFA link protection, and BGP PIC. Without this feature enabled, it would take time proportional to the number of paths going over the interface experiencing the link down event to failover to the backup path. With this feature enabled, the failover time would be constant regardless of the number of paths.

Class based forwarding (CBF) is a means for steering network traffic into colored tunnels based on one or more fields of the ingress traffic. Rephrased, CBF is forwarding of traffic based on “classes” which are derived from fields in the ingress packet headers and policies provisioned on the router.

Class Based Forwarding (CBF) provides a means for forwarding traffic through selected tunnels based on the traffic class of the incoming packet. Starting 4.32.2F CBF supports forwarding MPLS labeled traffic based on the EXP value in the incoming packet or the internal traffic class (TC) resolved from the parameters of the packet (e.g TC derived from EXP bits combined with port trust mode). Here, EXP bits refer to the Experimental bits in the MPLS header.

This feature provides the ability to track the reason why a BGP path is excluded from the BGP best path selection

In order to use the BST(Binary Search Tree) resources more efficiently for multicast, we are introducing a new CLI

This feature implements the ability to configure any tx serdes parameters via the CLI. This is useful to work around any L1 issues that customers may encounter due to suboptimal networks/links/transceivers.

With the 18.0 release, you can perform Client Connectivity Tests (CCT) in a network that has deployed proxy servers.  CCT lets you use the Access Point’s third radio as a client that can connect to another AP you want to test. This gives you the ability to proactively validate network connectivity, the reachability of network services, and the quality of experience for critical applications such as VoIP.  For more information on CCT,

With the 17.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces a redesigned dashboard for viewing client details. The following image shows the new client details dashboard:  Along with client and network details, the client details dashboard also contains multiple data points regarding client connectivity, performance, and application experience. From a single dashboard, you can conduct live troubleshooting, and review past data to identify and troubleshoot past issues, thus resulting in a faster resolution.

With the 19.0 release, the Client Listing UI provides more insights into the Wi-Fi capabilities, security settings, and encryption methods each connected client uses. It now includes precise security reporting, distinguishing between configured and actual encryption methods used by devices in mixed-mode SSIDs.

With the 13.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces the Client Explorer view. It helps you view the distribution of clients that are connected to Arista devices. 

Cloud HA feature provides active active redundancy between two vEOS router instances running in Cloud such as AWS and

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 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.

CVA 7 is a full rebuild of the CloudVision Appliance (CVA) software on a new architecture. The new architecture provides a much richer set of management and security primitives. It is fully controllable by REST API, Web based GUI or CLI, all of which expose all features.

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.

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.

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).

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.

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.

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

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.

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 allows the user to define a custom DSCP-To-TC map and apply it to an interface. The custom DSCP-To-TC map would only be applicable when the interface is in DSCP trust mode. This feature allows the user to classify packets based on DSCP bits of the IP header. The exact mapping can be specified using a custom DSCP-To-TC map.

With the 15.0 release, access points can authenticate themselves to the network using respective certificates. With access point (AP) VPN, AP uses the EAP-TLS protocol for authentication. Since EAP-TLS requires the client and network to authenticate themselves using respective certificates, the protocol is considered robust compared to exchanging shared secret and Xauth password. 

With the 14.0 release, you can provide a custom name to your system backup file and also rename it. You can back up the entire system or only the configuration files, and restore them when needed.

Network Administrators can create SSIDs at any location in CV-CUE, and the same SSID can be inherited from a parent to a child location. The inherited SSIDs, by default, share the same attributes as the parent location. With the 18.0 release, Administrators can override certain attributes of SSID at a child location without breaking the inheritance, so that the entire SSID configuration remains the same, except for the overridden attributes.

This feature can be used to customize hardware reported transceiver DOM thresholds to uniformize part-to-part differences in various parameter thresholds.
