Yangsuit NETCONF Invalid xpath

dundient — Thu, 02 May 2024 12:56:18 GMT

Hello, i need help with this error.

I want to check segment routing information, but get this error:

ERROR: Invalid xpath:
/ios:native/ios:segment-routing/ios-segment-routing:traffic-eng/ios-segment-routing:interface/ios-segment-routing:metric
Unknown xpath namespace prefix "ios-segment-routing" on segment 3 -- known prefixes are ['None', 'cisco-semver', 'inet', 'ios', 'ios-features', 'ios-ifc', 'ios-types']

Looks like your error message shows the "ios-segment-routing" namespace prefix is not recognized on segment 3 of the XPath. The known prefixes are ['None', 'cisco-semver', 'inet', 'ios', 'ios-features', 'ios-ifc', 'ios-types']. It _might_ be due to the missing definition or import of the YANG module that contains the "ios-segment-routing" prefix.

Start by verifying that the YANG module is compatible with your device's IOS version and features.

Hope this helps.

Hi I'm facing the same issue on new yangsuite installs (for multiple modules) - I belive yangsuite does not import all YANG modules from the YANG-set. I need to look into this and may open an issue at https://github.com/CiscoDevNet/yangsuite/issues

I let you know as soon as I know more.

So it looks like this kind of fault is raised depending on the yang module version used/imported in yangsuite.

https://github.com/YangModels/yang/tree/main/vendor/cisco/xe/17141 ==> Not working
https://github.com/YangModels/yang/tree/main/vendor/cisco/xe/17131 ==> Not working
https://github.com/YangModels/yang/tree/main/vendor/cisco/xe/1761 ==> Working

Try to use 1761 this one is working in my case.

HTH

Maybe it's a combination yangsuite/module version. Just DM me (via https://community.cisco.com/t5/notes/privatenotespage)
