Modelos de YANG do achado no Software Cisco IOS XR (cXR e eXR)

Introdução

Este original descreve como encontrar contudo uns outros modelos da próxima geração (YANG) em um roteador. A fim saber que YANG modela é apoiado em uma liberação particular de Cisco IOS® XR pode ser fastidioso, e os novos modelos são adicionados de vez em quando ou os modelos atuais são mudados. Para a referência, você pode igualmente encontrar modelos de YANG no github, mas não puderam ser atualizados.

Está aqui uma relação ao repositório do github. repositório do github

Modelos de YANG do achado no XR

Está aqui um exemplo onde você tem dois modelos que não são resolved:

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.

Depois que você compromete estas mudanças, você pode ver que os dois modelos estão resolvidos agora.

São aqui igualmente alguns exemplos que mostra que parte do trajeto do sensor pode ser especificado e o recipiente dos trabalho-ids deve ser especificado para a Cisco-IOS®-XR-NTO-MISC-SHPROCMEm-operação e não os processo-ids.

Modelos de YANG do achado no modo Admin (eXR)

Os mesmos diretores podem ser aplicados a fim encontrar um modelo de YANG no XR ao modo admin, a única diferença são o trajeto.

O trajeto onde os modelos de YANG são encontrados está aqui: /opt/cisco/calvados/1.00/etc/confd/yang
