Hi there, I've been experimenting w/ IOS-XE 16.5.1 on a CSR & have attempted to query the RESTCONF API. I have had some success, but, honestly, I'm having a hard time getting the information that I want. Being able to identify the correct URI to extract targeted data has been time-consuming because it's based on me just attempting random hit & miss URI combinations to get the data I want. I haven't been able to make sense of how to map the YANG models directly to a functional URI & was hoping that someone could provide me with some guidance on how to take a specific YANG model & then be able to access the desired information within. A concrete example: I have configured MPLS tunnels between 2 CSR's & am attempting to query the Cisco-IOS-XE-mpls.yang model. The closest URI I get to which provides meaningful info is as follows: http://192.168.3.41/restconf/api/running/ios:native/ios:interface/Tunnel/102?deep { "Cisco-IOS-XE-native:Tunnel": { "name": 102, "description": "OPS(test1<>test2)::blah::AAAAAAAAAAAA::blahblah", "ip": { "unnumbered": "Loopback1000" }, "Cisco-IOS-XE-tunnel:tunnel": { "destination": "10.253.24.2", "mode": { "mpls": { "traffic-eng": {} } }, "mpls": { "traffic-eng": { "path-option": { "working": [ { "id": 5, "explicit": { "name": { "exp-name": "TEST1_TO_TEST2_TE" } } } ] } } } } } } I arrived at this 100% via trial and error (guessing) and it doesn't contain alot of the information I want. How do I make sure I'm accessing the YANG data model I want ( Cisco-IOS-XE-mpls.yang) ? https:// <ADDRESS>/<ROOT>/<DATA STORE>/<[YANGMODULE:]CONTAINER>/<LEAF>[?<OPTIONS>] http://192.168.3.41/restconf/api/running/Cisco-IOS-XE-mpls :traffic-eng ???? My main issues are: 1) which datastore: operational/data/config/running ? some YANG models have "-oper" on the end of them, but otherwise I'm clueless. 2) once you know the datastore, how do you know how to access the specific module that you want? Is there a concrete process for doing this? In Cisco documentation (and other tutorials) I constantly see the same example of querying ieee-interfaces, but nothing w/ more detail. 3) is there a way to show API structure (like a list of keys, etc) through querying the API? 4) is there a way to output an entire yang data model (even if parts of it are empty) Any help or even a push in the right direction would be greatly appreciated! Thanks, Erik
