Enhancements to Data Models

This section provides an overview of the enhancements made to data models.

Install Label in oc-platform Data Model

The openconfig-platform (oc-platform.yang) data model is enhanced to provide the following data:

  • IOS XR software version (optionally with GISO label)

  • Type, description, operational status of the component. For example, a CPU component reports its utilization, temperature or other physical properties.

  • List of the committed IOS XR packages

To retrieve oc-platform information from a router via NETCONF, ensure you configured the router with the SH server and management interface: 
Router#show run
Building configuration...
!! IOS XR Configuration version = 7.3.2
!! Last configuration change at Tue Sep  7 16:18:14 2016 by USER1
!
......
......
netconf-yang agent ssh
ssh server netconf vrf default
interface MgmtEth 0/RP0/CPU0/0
    no shut
    ipv4 address dhcp
The following example shows the enhanced OPERATING_SYSTEM node component (line card or route processor) of the oc-platform data model:
<component>
<name>IOSXR-NODE 0/RP0/CPU0</name>
<config>
<name>0/RP0/CPU0</name>
</config>
<state>
<name>0/RP0/CPU0</name>

The following example shows the enhanced OPERATING_SYSTEM_UPDATE package component (RPMs) of the oc-platform data model:
<component>
<name>IOSXR-PKG/1 <platform>-isis-2.1.0.0-r732</name>
<config>
<name><platform>-isis-2.1.0.0-r732</name>

Associated Commands

  • show install committed—Shows the committed IOS XR packages.

  • show install committed summary—Shows a summary of the committed packages along with the committed IOS XR version that is displayed as a label.

Description

YANG Data Models for MPLS OAM RPCs

Release 7.3.2

This feature introduces the Cisco-IOS-XR-mpls-ping-act and Cisco-IOS-XR-mpls-traceroute-act YANG data models to accommodate operations, administration and maintenance (OAM) RPCs for MPLS and SR-MPLS.

You can access these Cisco IOS XR native data models from the Github repository.

The Cisco-IOS-XR-mpls-ping-act and Cisco-IOS-XR-mpls-traceroute-act YANG data models are introduced to provide the following options:

  • Ping for MPLS:

    • MPLS IPv4 address

    • MPLS TE

    • FEC-129 Pseudowire

    • FEC-128 Pseudowire

    • Multisegment Pseudowire

  • Ping for SR-MPLS:

    • SR policy name or BSID with LSP end-point

    • SR MPLS IPv4 address

    • SR Nil-FEC labels

    • SR Flexible Algorithm

  • Traceroute for MPLS:

    • MPLS IPv4 address

    • MPLS TE

  • Traceroute for SR-MPLS:

    • SR policy name or BSID with LSP end-point

    • SR MPLS IPv4 address

    • SR Nil-FEC labels

    • SR Flexible Algorithm

The following example shows the ping operation for an SR policy and LSP end-point:

<mpls-ping xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-mpls-ping-act">
  <sr-mpls>
  <policy>
    <name>srte_c_10_ep_10.10.10.1</name>
