EOS 4.25.2F TOI

This feature adds support for a selected set of configured interfaces to collect egress flow samples. Egress sFlow can be configured on ethernet and port-channel interfaces.

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.

Access Control Lists (ACL) use packet classification to mark certain packets going through the packet processor pipeline and then take configured action against them. Rules are defined based on various fields of packets and usually TCAM is used to match packets to rules. For example, there can be a rule to match the packet source IP address against a list of IP addresses, and drop the packet if there is a match. This will be expressed in TCAM with multiple entries matching the list of IP addresses. Number of entries is reduced by masking off bits, if possible. TCAM is a limited resource, so with classifiers having a large number of rules and a big field list, TCAM runs out of resources.

This article describes the Tap Aggregation MPLS Pop feature. The purpose of this feature is to support tools that do not parse MPLS labels and therefore need the switch to remove (pop) the MPLS header.

Traffic steering is an existing Tap Aggregation feature that supports redirection of traffic based on configurable

As of EOS-4.25.2F some advanced Tap Aggregation features require the hardware forwarding profile to be set. On EOS-4.25.2F these features are MPLS Pop and 802.1br-E/VN Tag Stripping.

This feature adds support for viewing the Digital Optical Monitoring (DOM) parameters for the optics that support

Unicast Reverse Path Forwarding (uRPF) can help limit malicious traffic on a network. uRPF works by enabling the

VLAN tagged MACsec refers to frames that have a VLAN tag between the MAC source address and the MACsec ethertype.  This VLAN tag is unencrypted (in the clear) so that intermediate devices between the MACsec endpoints can forward the MACsec frames based on this unencrypted VLAN tag.

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

This document describes the support of VxLAN Bridging and Routing on the R3 series of DCS 7280, 7500 and 7800 Arista
