Contents

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

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 mapping 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");

Implementation RPC

This is only valid for NETCONF 
TODO

Implementation Notification

  • Create notification instance: 
   ClMgtNotify notiInstance("<notification name defined in Yang file>") 
   Example:
     ClMgtNotify         addrFailoverNotify("AddressFailover");
  • Add notification parameters: 
   notiInstance.addLeaf("<leaf name>", "<default value>")
   Example:
     addrFailoverNotify.addLeaf("ipAddress", netif_eth0.IpAddress());
  • Add notification to module: 
   yangModule.addMgtNotify(&notiInstance)
   Example:
     yangModule.addMgtNotify(&addrFailoverNotify);
  • Send notification: 
   notiInstance.sendNotification()
   Example:
     addrFailoverNotify.sendNotification();

Building your model:

Right click project -> Build Project

Running your model:

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

FAQs:

Question: NETCONF close your connection with yumacli or mgtcli

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

Question: NETSNMP respone with timeout for snmpwalk/snmpget/snmpset command

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.

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

Answer:

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