Starting EOS 4.15.0F, a BGP route reflector can preserve the BGP attributes (next hop, local preference and metric)

Provisioning Settings allows you to configure CloudVision's default behavior when pushing configuration and image changes to devices. Each setting relates to an action used in Change Control. Ordinarily you should only need to use the default settings, but you can alter them for more control over CloudVision and EOS interactions for devices in your network. 

This document describes the enhancements to Arista's IEEE 1588 PTP implementation introduced in EOS 4.15.0F.

CloudVision provides more than 20 overlay options to help you visualize the properties of network devices, interfaces, and links. Use the PTP overlay to visualize the topology of PTP enabled devices and their links. At a glance, you can see which device in a PTP domain is the grandmaster and which devices belong to a PTP domain.

This feature makes ARP and ND packets use a higher priority output queue when software forwarded on the switch. Doing

Since, now there can be multiple inputs, conflicts may arise. Non conflicting configurations are when non default

QSFP+ modules that support TX power DOM will now display the reported TX power value via show interfaces transceiver.

Forward Error Correction (FEC) is required with some QSFP100 media to achieve error free operation of the link when

RACL divergence enables the optimization of the utilization of hardware resources by installing ACLs only on the

TCAM sharing between different VLAN Interfaces when they have same ACL attached : Configurable via CLI

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.

In the 14.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces a new Report, WiFi-Radios Instantaneous.

Arista WM gathers a wealth of data about the wireless deployment. The data gathered includes Wireless Intrusion

Equal Cost Multi path (ECMP) provides the ability to load share traffic across multiple next hops.

When this feature is enabled, responses to gNMI get requests as well as NETCONF get-config responses will contain the default values for YANG leafs if those leafs do not have any other value. This means that where a leaf value would normally be returned in a response, its default value (as defined in the YANG model) will be returned if the leaf does not have any other value assigned to it. Before this change, leafs that had a default value would not have been included in gNMI get responses.

The transmit power configured on UI is now treated as EIRP (Equivalent Isotropically Radiated Power) instead of

The BGP labeled unicast (LU) RFC is used to advertise BGP routes with a stack of MPLS labels, thereby allowing

This feature provides support for advertising IPv4 unicast Network Layer Reachability Information (NLRI) with

Multi Agent, Platform independent. This feature supports RFC 7606, which  provides improved security and

With the 16.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces the Client Roaming Explorer. It provides a graphical and tabular view of a client’s roaming events from one access point (AP) to another AP.

Creating a scope, or attribute, for your SAML provider allows you to pass CloudVision roles from the corresponding identity provider to CloudVision. This allows CloudVision user accounts to be automatically created with these roles when a new user logs in with that provider.

The broadcast queue towards the CPU is shared among all interfaces of the forwarding chip. So broadcast storm on a

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

Routing control functions (RCF) is a language that can be used to express route filtering and attribute modification logic in a powerful and programmatic fashion.

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

RSVP-TE P2MP LSR adds transit support for Point-to-Multipoint (P2MP) LSPs. Specifically the feature adds protocol support for the transit role as described in RFC 4875.

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 individual mirroring session: when the session's sample rate N is specified, a packet eligible for mirroring will have a 1/N chance of being mirrored, that is, 1 packet is mirrored for every N packets.

With the 17.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces the ability to schedule the generation of Client Visibility and Client Association reports. You can schedule report generation on a one-time basis or recurring basis.  Note: Users with Admin or Operator roles only can schedule a report.

With the 13.0 release, you can schedule the Automatic Channel Selection (ACS) to run at a specific time of the day and minimize service disruption.

Secondary private VLAN trunk ports are introduced in the EOS 4.15.2F release. This feature can

With the 16.0.1 release, clients connecting to the 6 GHz band can seamlessly connect to OWE-enabled SSIDs having Transition Mode. Arista APs support the Enhanced Open security protocol with Transition Mode built for open networks. Enhanced Open is based on Opportunistic Wireless Encryption (OWE). It is supported only in WiFi 6 and higher AP models. A few examples are C-360, C-260, C-250, C-230, O-235, etc.

The Dynamic Load Balancing (DLB) feature is currently supported in the DCS-7060 Arista switches in order to provide an alternative to the hash-based ECMP load balancing, which selects the next hop for routed packets using a static hash algorithm. DLB considers the state and quality of the port while assigning egress ports to packets, resulting in a more even flow. The state of each port member is determined by measuring the amount of data transmitted from a given port and the total number of packets enqueued to a given port.
