Ingress policing provides the ability to monitor the data rates for a particular class of traffic and perform action when traffic exceeds user-configured values. This allows users to control ingress bandwidth based on packet classification.  Ingress policing is done by a policing meter which marks incoming traffic and performs actions based on the results of policing meters.

The goal of IAR operation is to minimize the CPU processing and churn in hardware by identifying a set of nexthop adjacencies such that updating those adjacencies in-place is sufficient to correctly forward the traffic quickly for all the affected routes.

Sflow samples can be augmented with additional Extended gateway data by getting data from BGP in addition to

This feature allows failover to the backup path to occur in constant time per interface going down for features such as RSVP link protection, RSVP node protection, TI-LFA link protection, and BGP PIC. Without this feature enabled, it would take time proportional to the number of paths going over the interface experiencing the link down event to failover to the backup path. With this feature enabled, the failover time would be constant regardless of the number of paths.

In the Centralized Anycast Gateway configuration, the Spines are configured with EVPN IRB and are used as the IP

In EOS 4.22.0F, EVPN VXLAN all active multi homing L2 support is available. A customer edge (CE) device can connect to


Fastdrop static is a feature that allows the static multicast routing agent to respond to cache miss messages and

The FEC (= Forward Error Correction) traffic analyzer is designed to estimate the performance of the FEC layer, identify error statistics, and the source of correlated errors on physical interfaces.

This feature adds support for offloading BFD Transmit path to hardware (ASIC) for specific types of BFD sessions. This will improve accuracy of transmit timer implementations for BFD (especially with fast timers like 50 ms) and relieve pressure on the main CPU in scenarios of scale.

This feature allows classification of packets based on the inner VLAN value along with the VLAN and CoS bits in a double tagged packet.

Mirror on drop is a network visibility feature which allows monitoring of MPLS or IP flow drops occurring in the ingress pipeline. When such a drop is detected, it is sent to the control plane where it is processed and then sent to configured collectors. Additionally, CLI show commands provide general and detailed statistics and status.

On DCS 7280E, DCS 7500E, DCS 7280R, DCS 7500R, DCS 7020R, DCS 7280R2, DCS 7500R2 systems, it is possible to select

This feature enables per port TC-To-COS mapping, where TC represents Traffic-Class and COS represents Vlan tag PCP bits. While at present there is a global TC-To-COS mapping, we can use the TC-To-COS feature to create custom profiles which can be applied to the required interfaces.
