BGP Prefix Independent Convergence (PIC Edge) refers to fast re-convergence of traffic destined for BGP prefixes on a network event affecting the best path(s) such that the time taken to switch traffic from the active best path(s) to the next best path (i.e. backup path) is independent of the number of prefixes. The above behavior is achieved by pre-programming the best path and alternate backup path in the forwarding agent in steady state. 

The BGP Prefix Independent Convergence (PIC Edge) is an existing feature that was first introduced in EOS 4.15.0F.

The Campus Dashboard provides an overview of your network state. Devices stream telemetry data to CloudVision in real time, giving you immediate and up-to-date insights into your network’s health. The timepicker can be used to view historic data of the network state.

This is an addition to the SSL certificate and key management feature added in EOS 4.15.0F.

 With the 12.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces Channel Maps. This chart displays the number of clients and access points (APs) visible to the managed device at a time on a given channel.

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 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.

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 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.

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.

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.
