What's New in this Release

This chapter describes features that are new in the 21.2 release of CloudVision Cognitive Unified Edge (CV-CUE).

Monitoring and Troubleshooting

Infrastructure Dashboard

The Infrastructure Dashboard provides an overview of the health of all managed access points (APs). This dashboard provides a real-time health snapshot of your access points, covering connectivity status, performance metrics, link speed, power delivery, RF noise, channel usage, and distribution.

Advanced Parameters in Alerts

Configure the advanced alert parameters to fine-tune alert sensitivity and reduce false positives in diverse Wi-Fi environments. These parameters allow administrators to customize alert timing, volumetric thresholds, and apply contextual filters.

Operations

Unicast Wireless Clients for DHCP Requests

Configure the SSID settings to unicast a DHCP response directly to the client, without flooding the AP. This configuration sets the Broadcast bit to 0, indicating a unicast message. If the Broadcast bit is set to 1, it indicates a broadcast message. If a client has a default request for a broadcast response from the DHCP server, then enabling this setting overrides the client’s request and changes the DHCP server response to a unicast response.

Ignore Low RSSI Packets in High-Density Deployments

The Ignore Low RSSI Packet threshold is a radio setting, and you can configure it for each band. You must define the thresholds for RSSI and CCA-ED.

DHCP Options 16 and 17 for IPv6

Arista Wi-Fi Access Points (AP) use DHCP Options 16 and 17 for IPv6 to discover and connect to a specific CV-CUE server on-premises or in the cloud. For a dual-stack DHCP server, IPv4 is preferred over IPv6.

Jumbo Frame Support in Access Points

Arista Access Points (AP) support configuring the Maximum Transmission Unit (MTU) to send large packets without fragmentation. The default MTU is 1500 bytes. MTU configuration is supported for IPv6 and IPv4. MTU configuration applies to the Bridge and Network VLAN. It’s not available for Tunnel VLAN. It is an AP-level setting and applies to all APs at a location.
