Download Framework via github

root@desktop:/# git clone https://github.com/OpenClovis/SAFplus-Mgt.git <path>

Building thirdparty library

root@desktop:/# cd <path>/3rdparty
root@desktop:<path>/3rdparty# make

Build CPP component on SAFplus Framework

This may be done in one of the following two ways:

Rebuild SAFplus

root@desktop:/# cd <safplusdir>
root@desktop:/# mkdir -p prebuild
root@desktop:/# export BUILD_CPP=1 
root@desktop:/# <safplusdir>/src/SAFplus/configure --with-safplus-build
root@desktop:/# cd build/local
root@desktop:/# make

Build your model with extra configure

root@desktop:/# cd <project root>
root@desktop:<project root># export BUILD_CPP=1 
root@desktop:<project root># <safplusdir>/src/SAFplus/configure --with-safplus-build --with-model-name=<your model name> 
root@desktop:<project root># cd <your model name>/build/local
root@desktop:/# make

Development your source code

• Using OpenClovis IDE:

File -> Import -> General -> Existing Projects into Workspace -> Next -> Locate <git checkout Framework path>/models -> Finish.

File:Import fw model.png

Defined your YANG model

Using vim, gedit or IDE to create your Yang model and put those models into <model>/src/extras/share/netconf/modules.

• In case you would like to convert YANG model to MIB model, follow instruction at the link: Convert YANG to MIB model and also put the MIB model at <model>/src/extras/share/snmp/mibs.

Implementation your model

Create your C++ classes that derive from ClMgtObject base class or ClMgtObjectContainer or ClMgtList depend on your yang model.

• ClMgtObject: TODO
• ClMgtObjectContainer: TODO
• ClMgtList: TODO

Example

class NetworkInterface : public ClMgtObjectContainer {
private:
   ClMgtIndex<string>        name;  // Interface name ex. "eth0".  This is also the index into this data.
   /*
    * "Prov" objects are "provisioned" -- that is, they are stored in the replicated database.
    * When "bind" is called, these object will be loaded from the database's "active" configuration.
    * Once bound when the database is modified via an incoming provisioning request, these objects are notified.
    * ClMgtProv is a template that wraps provisioning functionality around any fundamental type (by fundamental I mean
    * any type that is serializable via memcpy).
    */
   ClMgtProv<bool>          adminStatus;  // Administrative status.  If you want this to be "up" set it to "true". "False" = "down"
   ClMgtProv<ClIpAddress>   ipAddress;
   ClMgtProv<ClIpAddress>   netMask;
   ClMgtProv<ClIpAddress>   gateway;
   ClMgtStat<uint64_t>      errorCount;   // Cumulative count of errors
   /*
    * ClMgtHistoryStat is an in-ram statistic that returns cumulative count AND contains sub-nodes which are arrays of 10 values containing historical (starting now and extending into the past) data:
    * 5sec: the cumulative count within second 0-5, 5-10, 10-15, ...
    * 1min:
    * 5min:
    * 1hr:
    * 1day:
    * 1week:
    * 4weeks:
    * 1year:
    */
   ClMgtHistoryStat<uint64_t> bytesSent;
   ClMgtHistoryStat<uint64_t> bytesReceived;
public:
   NetworkInterface(const char* objName);
   virtual ~NetworkInterface();
   void initialize(std::string ifName, ClMgtObject* parent);
   void get(void **ppBuffer, ClUint64T *pBuffLen);
   void set(void *pBuffer, ClUint64T buffLen, ClTransaction& t = NO_TRANSACTION);
   string IpAddress();
};

Declare your YANG/MIB model:

• With YANG module:

/* 
 * Declare "<your yang model name>" module 
 * Should be defined at your main program or header file.
 */
ClMgtModule yangModule("<your yang model name>");
/*
 * Initialize the module
 */
yangModule.loadModule();

• With MIB model:

/* 
 * Declare "<your mib module name>" module 
 * Should be defined at your main program or header file.
 */
ClMgtModule         mibModule("<your mib module name>");
/*
 * Initialize the module
 */
mibModule.loadModule();

Initialize mapping between object instance and YANG/MIB model

• With Yang model

Create object instance:

yourclass objectInstance("<name of node tree object intend to create the mapping>")

• Example:

/* 
 * Should be defined at your main program or header file.
 */
NetworkInterface    netif_eth0("interfaces");

Initialize the mapping for object instance:

objectInstance.bindNetconf("<your yang model name>", "<your xpath model>");

• Example:

/* 
 * Bind the "active" network interface to 
 * a "/ethernet/interfaces" subtree within
 * the "network" module.
 */
 netif_eth0.bindNetconf("network", "/ethernet/interfaces[name='eth0']");

With MIB model

Replace initialize mapping command with below API

object.bindSnmp("<your mib module name>", "<oid instance>");

• Example:

/* 
 * Bind the "active" network interface to 
 * a "/ethernet/interfaces" subtree within
 * the "network" module.
 */
 netif_eth0.bindSnmp("NETWORK", "1.3.6.1.4.1.99840.2.1.1");

Building your model:

Right click project -> Build Project

Running your model:

<model image>/etc/init.d/safplus start

FAQ:

Question: Cannot connect to NETCONF

Answer:

• If you are running your model with non-root user, port 830 cannot being listening. Your should manual running the script at <model image>/etc/init.d/customerScript.sh with root privileges and test your connect with below command:

• sudo sh <model image>/etc/init.d/customerScript.sh start --> to start sshd listening

or

• sudo sh <model image>/etc/init.d/customerScript.sh stop --> to stop sshd listening

Question: Make 3rdparty failed at libssh2: Need OpenSSL or Libgcrypt (such as Fedora or Centos)

Answer:

• sudo yum install libgcrypt-devel
