 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.

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.

CloudVision allows users to monitor a device’s environment by displaying graphs for temperature, power supply and fan speed. Power Supply shows the power used at each power socket on the device. Previously users could only view a visualization of output power. A visualization for input power is now available to view.

With the 12.0 release, you can configure DHCP fingerprinting to allow or deny clients getting connected to an SSID. Using DHCP fingerprinting, you can identify the operating system (OS) of the client based on the DHCP exchange packets between the client and the DHCP server.
