This feature supports counting ECN-marked packets (ECN = Explicit Congestion Notification) on a per egress port per tx-queue basis. The feature can be used to gather these packet counts via CLI or SNMP. There are two cases when an ECN-marked (congestion) packet is counted on the egress port/queue:

EOS-4.24.0 adds support for hardware-accelerated sFlow on R3 systems. Without hardware acceleration, all sFlow processing is done in software, which means performance is heavily dependent on the capabilities of the host CPU. Aggressive sampling rates also decrease the amount of processing time available for other EOS applications.

ITU-T G8275.1 is a PTP profile defined by ITU-T for telecommunication applications. It defines a set of functions from the IEEE 1588 to achieve phase/time synchronization with full timing support from the network (meaning, all of the network devices support PTP).

RSVP-TE, the Resource Reservation Protocol (RSVP) for Traffic Engineering (TE), is used to distribute MPLS labels for steering traffic and reserving bandwidth. The Label Edge Router (LER) feature implements the headend functionality, i.e., RSVP-TE tunnels can originate at an LER which can steer traffic into the tunnel.

Subinterfaces divide a single ethernet or port channel interface into multiple logical L2 or L3 interfaces based on the 802.1q or 802.1ad tags of incoming traffic. Subinterfaces are commonly used in the L2/L3 boundary device, but they can also be used to isolate traffic with 802.1q tags between L3 peers by assigning subinterfaces to different VRFs or different L2 bridging domains.

IPv4 Unicast Reverse Path Forwarding (uRPF) can help limit malicious IPv4 traffic on a network. uRPF works by enabling the router to verify reachability (routing) of the source IP address (SIP) in the packet being forwarded. If the SIP is determined to not be a valid address, the packet is dropped.

This document describes the OSPFv2 feature that allows the setting of “Down” (DN) bit in type-5 and type-7 LSAs. The DN Bit is a loop prevention mechanism implemented when OSPF is used as CE - PE IGP protocol. Its usage in OSPF is explained by RFC4576. By default, OSPF honors the DN-bit in type-3, type-5 or type-7 LSAs in non-default VRFs.
