    What's New in Release 6.3.1

    Cisco is continuously enhancing the product with every release and this section covers a brief description of key features and enhancements. It also includes links to detailed documentation, where available.

    Software Features Introduced in Cisco IOS XR Software Release 6.3.1

    Pseudowire Headend (PWHE)

    The Pseudowire Headend (PWHE) feature provides a Layer 3 (L3) virtual interface representation of a pseudowire (PW) on an service provider edge (PE), that allows the backhaul of customer packets over PWs and the application of L3 features, such as QoS (for example: policing and shaping) and access lists (ACLs) on customer packets on the PW. In Release 6.3.1, PWs operate in bridged interworking mode; only VC type 4 or VC type 5 is supported.

    For more information on this feature, see the Implementing MPLS Layer 3 VPNs chapter in the Virtual Private Network Configuration Guide for Cisco NCS 6000 Series Routers, IOS XR Release 6.3.1.

    ISSU for BFD session over MPLS-TE tunnel

    In-Service Software Upgrade (ISSU) is supported for BFD session over MPLS-TE tunnel (BFDoTE) feature. For more information about ISSU, see System Setup and Software Installation Guide for Cisco NCS 6000 Series Routers.

    ISSU for BGP Flowspec

    In-Service Software Upgrade (ISSU) is supported for BGP flow specification (flowspec) feature. For more information about ISSU, see System Setup and Software Installation Guide for Cisco NCS 6000 Series Routers.

    Cross Rack Pairing

    Cross rack pairing allows inter-rack pairing where route processor (RP) of one rack is paired with the RP of another rack through an algorithm. This daisy-chain pairing of racks provides high availability against rack failures.

    To enable pairing RPs between racks, and associated scenarios, see Perform Cross Rack Pairing chapter in the System Setup and Software Installation Guide for Cisco NCS 6000 Series Routers.

    IP-in-IP Decapsulation

    IP datagrams that are encapsulated with an outer IP header before transmission through an IP tunnel are stripped of the header on exiting the tunnel. IP-in-IP decapsulation is now supported on NCS 6000.

    For more information on this feature, see the Interfaces and Hardware Component Configuration Guide for Cisco NCS 6000 Series Routers, IOS XR Release 6.2.x.

    YANG Model Support for IOS XR Admin Plane

    YANG data models are supported for IOS XR admin plane. All the IOS XR actions are supported in System Admin plane.The actions introduced in this release are:

    • System Process Mgmt : process (restart)

    • System Process Mgmt : Reload (System Admin virtual machine (VM) reload, line card (LC) reload)

    • System Process Mgmt : Reload (IOS XR VM node reload from System Admin)

    To see the list of actions and an example to use a System Admin action, see Components to Use Data Models chapter in the .

    Event-based Telemetry

    Telemetry provides a mechanism to stream data from the router at regular intervals. Event-based telemetry is used to collect data when a state transition occurs. This feature optimises the need to collect state information even when a change in the state does not occur, thus eliminating the data overhead at the router and the receiver.

    For more information about state transitions, and collecting event-based telemetry data, see Configure Event-based Telemetry chapter in the .

    OAM for BGP-SR

    The OAM for BGP-SR feature provides support for ping, traceroute, and treetrace (traceroute multipath) operations for LSPs signaled via BGP for IPv4 Prefix SIDs. This feature adds support for Segment Routing OAM operations in deployments with combinations of BGP and LDP signaled LSPs.

    For more information on this feature, see the Using Segment Routing OAM chapter in the

    ERSPAN with UDF

    ERSPAN with UDF feature enables the device to match on user-defined fields (UDFs) of the outer packet fields, either header or payload, and to send the matching packets to the ERSPAN destination. This feature helps you to analyze and isolate packet drops in the network.

    For more information, see the Interface and Hardware Component Configuration Guide for Cisco NCS 6000 Series Routers, IOS XR Release 6.3.x.

    Multi-chassis SDR

    The Secure Domain Routers (SDRs) are a means of dividing a single physical system into multiple logically separated routers. The Multi-chassis SDR feature enables you to create named SDRs on a NCS6K multi-chassis system. In previous releases, named SDR creation was possible only on single-chassis system. As in previous releases, a maximum of three named SDRs can be created. However, with multi-chassis setup more resources like line cards and its memory and CPU can be allocated to each SDR. This results in more compute power with each SDR.

    For more information on, see the Configuring Secure Domain Routers chapter in the System Management Configuration Guide for Cisco NCS 6000 Series Routers.

    Online Diagnostics Support

    Cisco NCS 6000 Series Routers supports Online Diagnostics. This feature enables you to test and verify the hardware functionality when connected to a live network. Scheduled health monitoring and diagnostics ensures system High Availability (HA). You can take appropriate resolution measures in less time as the diagnostic test results help in isolating the location of the problem.

    Cisco NCS 6000 Series Routers supports File System Diagnostic tests. For more information on this, see Online Diagnostics Software chapter in System Monitoring Configuration Guide for Cisco NCS 6000 Series Routers, IOS XR Release 6.3.x. For the list of Online Diagnostic commands and other command details, see Online Diagnostic Software commands chapter in System Monitoring Command Reference for Cisco NCS 6000 Series Routers.
