There are no new hardware features for this release.

• Auto In-Service State for Transceiver

  The transceiver module is a logical entity that represents a Transceiver equipment. The module can be created using a CLI command or created automatically when the Transceiver (pluggable) is inserted into a port. The transceiver connected to port supports the Auto In-Service State (AINS) functionality. For example, if an alarm is raised during the AINS state, then the alarm is not reported, and the syslog is not generated. You need to enable AINS under the alarms profile and the profile should be attached to the corresponding port.

  For more information, see Auto In-Service States, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• BGP Tracking

  The selective address tracking for Border Gateway Protocol (BGP) next hop fallover with maximum-metric can be enabled using the neighbor ip-address fall-over route-map command.

  For more information on the command, see Cisco IOS IP Routing: BGP Command Reference.

• Card Protection for STS-1 Electricals

  The router supports electrical card protection feature with 1:1 protection, or during events such as when interface module stops responding, software stops responding, or issues in other hardware components.

  For more information, see 48-Port T3/E3 CEM Interface Module Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• DSCP Preservation of MLDP Traffic

  The Differentiated Services Code Point (DSCP) value does not change on both the uniform and pipe modes.

  For more information, see QoS: Classification Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• EVPN Single-Homing

  The EVPN Single-Homing feature utilizes the functionality defined in RFC 7432 (BGP MPLS-based Ethernet VPN), to achieve single-homing between a Provider Edge (PE) and a Customer Edge (CE) device.

  For more information, see the MPLS Layer 2 VPNs Configuration Guide, Cisco IOS XE 17 (NCS 4200 Series).

• EVPN-VPWS Single Homing over Segment Routing

  EVPN-VPWS single homing is a BGP control plane solution for point-to-point services. It has the ability to forward traffic from one network to another using Ethernet Segment without MAC lookup. EVPN-VPWS single homing works on both IP and SR core. IP core is used to support BGP while the SR core is used to switch packets between the endpoints.

  For more information, see the Segment Routing Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).
• Facility Protocol Status Support

  The routers report the protocol status using syslog or trap alarm notifications. Few syslogs and traps are not cleared when the router gets disconnected or reloaded. As a result, the alarms are not notified.

  To avoid this, a new command, show facility protocol status, is introduced that displays the output of the following routing protocols status at any interval of time: IS-IS, OSPF, BGP, LDP, PTP, HSRP, BFD, TE tunnels, Bundles, pseudowires, EVPN pseudowires, CFM, SYncE, and sensor threshold violations.

  For more information, see the see the Cisco NCS 4200 Series Software Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• IPSLAs TWAMP Responder

  The IETF Two-Way Active Measurement Protocol (TWAMP) defines a standard for measuring round-trip network performance between any two devices that support the TWAMP protocols. The TWAMP control protocol is used to set up performance measurement sessions. It is also used to send and receive performance measurement probes.

  For more information on TWAMP Responder, see the IP SLAs Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• IPv4 Interworking Support for MLPPP Interfaces

  The Multilink Point-to-Point (MLPPP) interworking supports IPv4 Layer 2 VPN Interworking with T1 or E1 bundles on the Cisco RSP3 module. The MLPPP interworking enables service providers (offering relatively low-speed links) to use MLP and spread traffic across them in their MPLS networks. The MPLS Multilink PPP feature reduces the number of Interior Gateway Protocol (IGP) adjacencies and facilitates load sharing of traffic.

  For more information, see 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• IPv6 Interworking Support for MLPPP Interfaces

  The Multilink Point-to-Point (MLPPP) interworking supports IPv6 Layer 2 VPN Interworking with T1 or E1 bundles on the Cisco RSP3 module. The MLPPP interworking enables service providers (offering relatively low-speed links) to use MLP and spread traffic across them in their MPLS networks. The MPLS Multilink PPP feature reduces the number of Interior Gateway Protocol (IGP) adjacencies and facilitates load sharing of traffic.

  For more information, see 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• IPv6 Interworking Pseudowire Support on HDLC or PPP Serial Interfaces

  The IPv6 interworking is supported for Layer 2 VPN interworking mode. The IPv6 interworking is supported only for HDLC or PPP to Ethernet. Layer 3 termination is supported with serial interfaces with HDLC or PPP encapsulation.

  For more information, see 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• IPv6 Support for Interworking Multiservice Gateway Access Circuit Redundancy

  The IPv6 interworking is supported with ACR for Layer 2 VPN.

  For more information, see 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• L3VPN Support on mLACP

  Layer 3 VPN on multichassis LACP (mLACP) is supported in the Cisco RSP3 Module using the port-channel mc-lag command.

  For more information on the mLACP support, see Ethernet Channel Configuration Guide Cisco IOS XE 17 (Cisco NCS 4200 Series).

• Lawful Intercept

  The Lawful Intercept (LI) feature provides electronic surveillance as authorized by a judicial or administrative order for service provider routers. The Lawful Intercept is based on RFC3924 and Simple Network Management Protocol Version 3 (SNMPv3) provisioning architecture.

  For more information on Lawful Intercept, see the System Security Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• PTP Multiprofile

  The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a network. The PTP Multiprofile support is configured on a PTP boundary clock by translating one PTP profile at PTP slave port to other PTP profile at PTP master port. To translate PTP properties from one profile to other, a special type of inter-op clock-port is introduced. This special clock-port is configured with the required profile and domain information.

  For more information on PTP Multiprofile, see the Timing and Synchronization Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• Oversubscription Support for NCS4200-1T16G-PS

  Egress packet classification is performed based on priority-based flow-control (PFC) to ensure that there are no drop in packets.

  For more information on oversubscription, see Cisco NCS 4200 Router Series Configuration Guide, Cisco IOS XE 17.

• Segment Routing Low Latency Network Slice

  This feature allows the advertisement and reception of the extended TE link delay metrics without any additional configuration required in IS-IS, OSPF or BGP-IS. When the link delay values are configured, they are flooded in the PCE topology and when the path computation is requested, these values are used for path calculation.

  For more information, see the Segment Routing Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

• Segment Routing Performance Measurement Link Delay Metrics

  Network performance metrics such as packet loss, delay, delay variation, and bandwidth utilization is a critical measure for traffic engineering (TE) in service provider networks. These metrics provide network operators with information about characteristics of their networks for performance evaluation and helps to ensure compliance with service level agreements. The service-level agreements (SLAs) of service providers depend on the ability to measure and monitor these network performance metrics.

  For more information, see the Segment Routing Configuration Guide, Cisco IOS XE 17 (Cisco NCS 4200 Series).

There are no new hardware features for this release.

• SADT Overhead Accounting

  FPGA measures parameters such as throughput, frame loss, jitter, and delay for SADT.
