Download Framework via github

Building thirdparty library

Building CPP component on SAFplus Framework

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

Re-building 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

Building 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

System provides a set of data modeling classes to build a flexible data model which have object-oriented relationships (containment, inheritance, association). User can implement his own C++ classes derived from the MGT base classes to match with the model defined in the input Yang file.

• ClMgtModule
• ClMgtObject
• ClMgtContainer
• ClMgtList
• ClMgtIndex
• ClMgtProvision
• ClMgtStatistic
• ClMgtHistoryStatistic
• ClMgtRpc
• ClMgtNotification

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:

/*

* Declare "<your model name>" module

* Should be defined at your main program or header file.

*/

ClMgtModule dataModule("<your model name>");

/*

* Initialize the module

*/

dataModule.loadModule();

Initialize maping between object instance and NETCONF/SNMP model

• With NETCONF

• 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 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 SNMP

Replace initialize mapping command with below API

object.bindSnmp("<your model 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:

Running your model:

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

FAQs:

Answer:

This may cause by your sshd deamon Subsystem is still not running normal.

Solution: 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:

root@desktop:/#sudo <model image>/etc/init.d/customerScript.sh start --> to start sshd listening

or

root@desktop:/#sudo <model image>/etc/init.d/customerScript.sh stop --> to stop sshd listening

Answer:

The snmp master agent is listening on port 1610 and communication string is "clovis". Those params can be defined by your at <model>/src/config/snmpd.conf.

Answer:

root@desktop:/# sudo yum install libgcrypt-devel
