• Configurable Y.1564 Service Activation Frame Sizes and EMIX Support

  Enterprise traffic (EMIX) packet size (default abceg pattern) is supported on both, Cisco ASR 900 RSP2 and RSP3 modules. For EMIX traffic, ITU-T Rec. Y.1564 packet sizes of 64, 128, 256, 1024, and 1518 bytes are supported. On the Cisco RSP3 module, it is supported in FPGA-based SADT.

  For more information, see the IP SLAs Configuration Guide, Cisco IOS XE 17 (Cisco ASR 900 Series).

• OPTICS: ONS-SI-GE-EX and ONS-SI-GE-LX Support

  The optics, ONS-SI-GE-EX and ONS-SI-GE-LX are supported on the Cisco A900-IMA8CS1Z-M interface module.

  For more information, see the Optics Matrix for ASR 900.

• 8-Port SFP GE and 1-Port 10 GE 20G Interface Module Support

  The ASR 900 Combo 8-Port SFP GE and 1-Port 10 GE 20G Interface Module (A900-IMA1Z8S-CXMS) is supported on the Cisco RSP3 module and has the capability for SONET or SDH termination, SAToP, CESoP, and CEP.

  For more information on configuring the A900-IMA1Z8S-CXMS interface module, see the 1-Port OC-192 or 8-Port Low Rate CEM Interface Module Configuration Guide, Cisco IOS XE Gibraltar 16.12.x (Cisco ASR 900 Series).

  Note	The Multiservice Gateway features are not supported on this interface module for Cisco IOS XE Release 16.12.1.

• Five-Tupple Hash Load Balancing on the Cisco RSP3 Module

  The router supports different load balancing hash algorithms with combinations of MAC (Layer 2) or IP (Layer 3) headers on the RSP3 platform to find the hash key. The five-Tupple hash algorithm on RSP3 includes protocol field and Layer 4 port numbers while calculating the hash key.

  For more information, see the Ethernet Channel Configuration Guide Cisco IOS XE Gibraltar 16.12.x (Cisco ASR 900 Series).

• Generic Routing Encapsulation (GRE) Feature Updates

  Generic Routing Encapsulation (GRE) tunneling protocol provides a simple generic approach to transport packets of one protocol over another protocol by means of encapsulation.

  GRE supports the following features:

  • IPv4 or IPv6 Global over GRE (IPv4 Core)

  • VRF Lite over GRE

  For more information on GRE, see the IP Routing: GRE Configuration Guide, Cisco IOS XE Gibraltar 16.12.x (Cisco ASR 900 Series).

• Maximum Transmission Unit Support on Bridge Domain Interface for the Cisco RSP3 Module

  On the Cisco RSP3 module, filtering of IP packets and MPLS-IP packets that egress out Bridge Domain Interface (BDI) is performed based on the Maximum Transmission Unit (MTU) value of the physical interface. The constraint where the BDI inherits the physical interface’s MTU causes a limitation, for example, fragmentation or dropping of packets, during network deployments. To avoid such limitation, ensure that you configure BDI MTU.

  For more information on BDI MTU support, see the Carrier Ethernet Configuration Guide, Cisco IOS XE Gibraltar 16.12.x (Cisco ASR 900 Series).

• MPLS Layer 3 VPN Conditional Marking for the Cisco RSP3 Module

  The MPLS Layer 3 conditional marking feature marks the traffic with appropriate QoS group and sets policer to mark the color (discard class) based on Committed Information Rate (CIR) and Peak Information Rate (PIR) values. You can use the QoS group to create ingress policy map.

  For more information to configure MPLS Layer 3 VPN conditional marking, see the Quality of Service Configuration Guidelines, Cisco IOS XE Gibraltar 16.12.x (Cisco NCS 4200 Series).

• Psuedowire Scale Support

  Effective from the Cisco IOS XE release 16.12.x, CEM scale of 21,504 psuedowires is supported on the 1-Port OC-192 or 8-Port Low Rate CEM interface module.

  For more information on the pseudowire scale support, see the 1-Port OC-192 or 8-Port Low Rate CEM Interface Module Configuration Guide, Cisco IOS XE Gibraltar 16.12.x (Cisco ASR 900 Series).

• QoS Short-pipe Mode

  QoS short-pipe mode is supported on the RSP3 module. You can enable this feature using the SDM template.

  You can identify the egress traffic on an interface or on EVC and classify based on DSCP, mark qos-group, and color using the platform table-map command.

  For more information on how to enable short-pipe mode, see the Quality of Service Configuration Guidelines, Cisco IOS XE Gibraltar 16.12.x (Cisco ASR 900 Series).

• Segment Routing uLoop Avoidance

  The Segment Routing uLoop Avoidance feature prevents the occurrences of microloops during network convergence after a link-down event or link-up event.

  For more information on segment routing uloop avoidance, see Segment Routing Configuration Guide, Cisco IOS XE Gibraltar 16.12.x (Cisco ASR 900 Series).

• 4-port OC-48/OC-12/OC-3 + 12-Port A900-IMA3G-IMSG T1/E1 + 4-Port T3/E3 CEM Interface Module Support on A900-RSP3C-200-S RSP Module

  The 4-port OC-48/OC-12/OC-3 + 12-Port A900-IMA3G-IMSG T1/E1 + 4-Port T3/E3 CEM Interface Module (A900-IMA3G-IMSG) is supported on the A900-RSP3C-200-S RSP.

  For more information on A900-IMA3G-IMSG support, see the Cisco ASR 903 and ASR 903U Aggregation Services Router Hardware Installation Guide.

• ASR 900 Combo 8-Port SFP GE and 1-Port 10GE With CEM/iMSG, 20G Interface Module (A900-IMA1Z8S-CXMS)

  The ASR 900 Combo 8-Port SFP GE and 1-Port 10GE with CEM or iMSG 20G Interface Module is a cost-effective interface module (IM) that supports CEM features on the OCn interfaces. This interface module is supported on the Cisco ASR 903 Routers, Cisco ASR 907 Routers, and Cisco ASR 914 Routers.

  For more information about this IM for any of the supported routers, see the Cisco ASR 900 Series Aggregation Services Routers Hardware Installation Guides.
