Cisco Telemetery XPATH

Hello Team, 

Am trying to configure Cisco Telemetery but state showing invalid. The configuration is mentioned below:-

CiscoIOSXE54#show running-config | sec tele

Not 100% on this, but looking at what you posted the * and : characters are not properly placed. XPath filters should be precise and follow the correct YANG model paths, for exmaple /Cisco-IOS-XE-interfaces-oper:interfaces/interface

[Marcel Zehnder]

Hi, the xpath format is /<prefix>:<xpath> (no "/" after ":").

So in your case:

filter xpath /Cisco-ios-xe-oper:interface*:
filter xpath /interfaces-ios-xe-oper:interfaces/interface

filter xpath /ospf/if-state-change
filter xpath /ospf-ios-xe-oper:ospf-oper-data/ospfv2-instance/ospfv2-area/ospfv2-interface/state

filter xpath /ios-ospf/native/router/ios-ospf:ospf
filter xpath /ios:native/router/ios-ospf:router-ospf/ios-ospf:ospf

Here are some useful tools to get paths, this was and is still a bit tricky for me. So these tools usually help.
