IOS XR 9000 Netconf-yang Help

[olaf.debree]

Hi All,

I thought i would post this here as it did not receive much feed back on he support forum....perhaps the wrong place for an api question

I'm wondering if some one may assist with netconf-yang on IOS-XR version 6, Cisco documentation seems to be very limited here.

<edit-config> and <commit> seem to work well but i am having trouble with basic things like "no <command>".

Example: "no shutdown" for an interface. the "http://cisco.com/ns/yang/Cisco-IOS-XR-ifmgr-cfg"; yang file state that the existence <shutdown> tag will shut the desired interface. So the following XML works fine on an admin up interface.

<edit-config>
    <target>
        <candidate />
    </target>
  <config>
        <interface-configurations xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ifmgr-cfg">
            <interface-configuration>
                <active>act</active>
                <interface-name>GigabitEthernet0/0/0/1</interface-name>
                <InterfaceModeNonPhysical>0</InterfaceModeNonPhysical>
                <shutdown/>
            </interface-configuration>
        </interface-configurations>           
  </config>   
</edit-config>

There seems to be no reference to how to enable "no shut" the interface. I would except the below

<edit-config>
    <target>
        <candidate />
    </target>
  <config>
        <interface-configurations xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ifmgr-cfg">
            <interface-configuration>
                <active>act</active>
                <interface-name>GigabitEthernet0/0/0/1</interface-name>
                <InterfaceModeNonPhysical>0</InterfaceModeNonPhysical>
            </interface-configuration>
        </interface-configurations>           
  </config>   
</edit-config>

This is accepted by the router and committed but the interface admin state does not change

Thanks in advance

We can do the no shutdown operation as follows:

*****************************

*****************************

NETCONF SEND

------------

<rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

<edit-config>

<target><candidate/></target>

<config xmlns:xc="urn:ietf:params:xml:ns:netconf:base:1.0">

<interface-configurations xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ifmgr-cfg">

<interface-configuration>

<shutdown xc:operation="delete"/>

<active>act</active>

<interface-name>HundredGigE0/4/0/0</interface-name>

</interface-configuration>

</interface-configurations>

</config>

</edit-config>

</rpc>

corresponding config change:

RP/0/RP0/CPU0:fretta53#show configuration commit changes last 1

Building configuration...

!! IOS XR Configuration version = 6.0.1.14I

interface HundredGigE0/4/0/0

no shutdown

!

Olaf,

You should take a look at YDK to dramatically simplify model-driven automation.  Here are some pointers you may find useful:

Plus, there's a community dedicated to the APIs:

HTH!

Thank you, i tried it and it actually works, but couldn't guess it anyway.
