This lesson will show you how Configuration Data is created and used in YumaPro SDK.


Pre-Requisites


You should have completed “Installing YumaPro SDK” and the “Building and Installing the SIL”.


Example configuration data instrumentation


The first container in ietf-interfaces YANG module is container interfaces, it is a configuration container and provides YANG leafs that configure the system interfaces. Initially when you show the interfaces configuration with “sget /interfaces” you will see something as follows, an empty container:


user@localhost> sget /interfaces with-defaults=report-all
   
  Filling container /interfaces:
  RPC Data Reply 4 for session 3 [default]: 

 rpc-reply{
   data {
      interfaces {
      }
   }
 }


To configure an interface enter configuration from terminal mode, “conf term” and set some of the leafs of an interface. You need to create a name for the interface, such as“eth0”, and it must have a “type”. You will see below that when you enter “type ether” and then press <Tab> you will be prompted with options that are valid.


user@localhost> conf term

user@localhost# interfaces interface eth0

user@localhost@localhost(interface)# type ether[<Tab>]
    ethernet3Mbit  ethernetCsmacd

user@localhost@localhost(interface)# type ethernetCsmacd

user@localhost@localhost(interface)# description "some descriptive text"

user@localhost@localhost(interface)# exit

    Applying 1 edit

user@localhost@localhost(interfaces)# exit

user@localhost@localhost# exit

    RPC Data Reply 9 for session 3 [default]:

    rpc-reply {
      data {
        interfaces {
          interface  eth0 {
            name eth0
            description 'some descriptive text'
            type ianaift:ethernetCsmacd
          }
        }
      }
    }


After exiting “conf  term” mode the interface will be configured. You can see the interface now in using “sget /interfaces” again:


user@localhost> sget /interfaces with-defaults=report-all

    Filling container /interfaces:
    RPC Data Reply 10 for session 3 [default]:

    rpc-reply {
      data {
        interfaces {
          interface  eth0 {
            name eth0
            description 'some descriptive text'
            type ianaift:ethernetCsmacd
            enabled true
          }
        }
      }
    }


Code stubs in the SIL are created by make_sil_dir_pro for YANG configuration containers to mark where you should add your initialization, validation, apply, commit, rollback and cleanup code. You will see these with:


Code function or switch cases

Stub

<module_name>_init
/* put your module initialization code here */
<module_name>_init2
/* put your init2 code here */
AGT_CB_VALIDATE
/* description-stmt validation here */
AGT_CB_APPLY
/* database manipulation done here */
AGT_CB_COMMIT
/* device instrumentation done here */
AGT_CB_ROLLBACK
/* undo device instrumentation here */
<module_name>_cleanup
/* put your cleanup code here */
