400GBASE ZR transceiver is the industry’s first multi vendor DWDM standard, a Digital Coherent Optical module

This article describes a feature for Tap Aggregation mode, which strips IEEE 802.1BR E-Tag and Cisco VN-Tag headers from all tagged packets received on tap interface before delivering them out of tool interfaces.

BFD (Bidirectional Forwarding Detection) session telemetry allows for the collection of per session statistics as

The DHCP relay feature, forwards DHCP packets between a client and the DHCP server when the server is not in the same broadcast domain as the client. The DHCP relay should be configured on the gateway interface (SVI/ L3 interface) for the clients.

The feature allows assigning of class E addresses to interfaces by default with no option to turn that off and routing

The Segment security feature provides the convenience of applying policies on segments rather than interfaces or subnets. Hosts/networks are classified into segments based on prefixes. Grouping prefixes into segments allows for definition of policies that govern flow of traffic between segments. Policies define inter-segment or intra-segment communication rules, e.g. segment A can communicate with segment B but hosts in segment B can not communicate with each other.

In EVPN deployment with VXLAN underlay when an EVPN type 5 prefix is imported into an IP VRF, the IGP cost of the underlay

InfluxDB telemetry streaming feature enables telemetry data collection with Telegraf on box, and allows streaming

In a multihomed EVPN MPLS configuration, BUM packets sent from a non-designated forwarder (Non-DF) PE to a designated forwarder (DF) PE must carry ESI label advertised by the egress DF PE.

This feature may be used for redistributing OSPFv2 leaked and non leaked routes from one instance to another when

Sampled flow tracking with IPFIX export is supported on most of the Arista platforms. User configured sampling rate is used for sampling in ingress and/or egress direction on the configured interfaces. An EOS software agent on CPU processes samples received from hardware, samples are used to create flow records that are exported to IPFIX collectors. Refer to Sampled flow tracking TOI for additional details.

4.25.2F introduces storm control with packet per second support in the platforms listed below. TOI describing the

Prior to 4.25.2F, support for BGP PIC was restricted to locally identifiable failures such as link failures. If a

By default, sFlow samples that are generated have a fixed size: 128 bytes. This feature adds support for a

This feature addresses cases where the deployment infrastructure in an OpenStack setup which manages Virtual

This feature terminates GRE packets on a TapAgg switch by stripping the GRE header and then letting the decapped packets go through the normal TapAgg path. With this feature, we can use an L3 GRE tunnel to transit tapped traffic to the TapAgg switch over an L3 network. That would widely extend the available use cases for TapAgg.

In EOS 4.25.2F release, VRRP support is enabled on the following platforms,. DCS 7280R3. DCS 7500R3.
