소개
이 문서에서는 라우터에서 또 다른 YANG(Next Generation) 모델을 찾는 방법에 대해 설명합니다. 특정 Cisco IOS® XR 릴리스에서 어떤 YANG 모델이 지원되는지 알기 위해서는 지루할 수 있으며, 때때로 새로운 모델이 추가되거나 현재 모델이 변경될 수 있습니다. 참고로 github에서 YANG 모델을 찾을 수도 있지만 최신 버전이 아닐 수 있습니다.

XR에서 YANG 모델 찾기
다음은 해결되지 않은 두 모델이 있는 예입니다.

The first thing to do after going into the shell is to change directories to /pkg/yang. This is where the yang models are stored.
The models we specified in the configuration are not resolved because the models do not exist on the router as we can see from the 'ls' commands. When we search for the 'procmem' yang model
for instance we see that it has changed from Cisco-IOS®-XR-procmem-oper to Cisco-IOS®-XR-nto-misc-shprocmem-oper.
However, we should examine this file further to see if anything else has changed in the model structure.
As we can see with this model the container/list process-ids/process-id has changed to job-ids/job-id.

이러한 변경 사항을 커밋하면 이제 두 모델이 해결되었음을 확인할 수 있습니다.
다음은 센서 경로의 일부를 지정할 수 있으며 process-id가 아닌 Cisco-IOS®-XR-nto-misc-shprocmem-oper에 대해 job-id 컨테이너를 지정해야 함을 보여주는 몇 가지 예입니다.

관리 모드에서 YANG 모델 찾기(eXR)
XR to admin 모드에서 YANG 모델을 찾기 위해 동일한 주도자를 적용할 수 있지만 유일한 차이점은 경로입니다.
YANG 모델이 위치한 경로는 다음과 같습니다. /opt/cisco/calvados/1.00/etc/conpd/yang
