With the 13.0 release, CloudVision Cognitive Unified Edge (CV-CUE) can redirect onboarding clients to a dynamic URL defined by the RADIUS. If the  RADIUS access-accept request has a role and a redirection URL for a client, access points (AP) can redirect such client’s HTTP or HTTPS requests. 

Some data plane features on some switch platforms may require packets to be recirculated through the switch chip in

This feature allows to advertise routes learnt via BGP into IS IS network or IS IS routes into BGP network. It also

This feature removes an ARP entry when the physical port, on which the ARP entry's MAC address is learned, goes down.

This feature allows routing traffic across two Vrf domains on the same switch using an external loopback cable

In an MLAG setup, routing on a switch (MLAG peer) is possible using its own bridge/system MAC, VARP MAC or VRRP MAC.

With the 13.0 release, you can integrate SAML SSO with a captive portal for authentication. The SAML integration functionality is only available for captive portals hosted on the Arista Cloud. It is not available if the captive portal is hosted on third-party servers or on the access point.

Sampled Mirroring is an extension of the Mirroring feature and sampling is a property of the

Source ARP with a virtual IP is a new VARP feature. The purpose of this feature is to change the ARP request header's

With the 13.0 release, you can enable spatial reuse from CloudVision Cognitive Unified Edge (CV-CUE) to improve the spectral efficiency and optimally allocate resources to meet the Quality of Service (QoS). With spatial reuse, two or more Wi-Fi devices (AP or client) that support 802.11ax protocols can send transmissions simultaneously without any significant data loss.

Spectrum analysis is a tool to analyze the RF environment for interference. For monitoring and troubleshooting of wireless networks, you must be aware of the RF environment in which the  APs operate.
