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:
- 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 maping 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");
Implementation RPC for YANG model

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
