[SNMP4J] OID Name to OID Dot Notation and vice Versa

Discussion:

I hope this is a trivial fix, I am really new to SNMP4J.

I simply want to simply translate an OID name to a OID dot notation. I can find any clear documentation on how to do this.

Also do I need to compile new MIBS or simple provide the text files?

Below is just a test file to get me started

Any help Please!!!!

Thanks,

Maurice

public class SmiManagerTest {

public static void main(String[] args) {

SmiManager smiManager = null;

String sLicense = "";

try {

smiManager = new SmiManager(sLicense, new File("C:\\mibrepository"));
SNMP4JSettings.setOIDTextFormat(smiManager);
SNMP4JSettings.setVariableTextFormat(smiManager);

} catch (IOException e) {
e.printStackTrace();
}

try {

for (String sModule : smiManager.listModules()) {
System.out.println("Module: " + sModule);
}

} catch (IOException e) {
e.printStackTrace();
}

try {
smiManager.parse("sysContact.0");
} catch (ParseException e) {
e.printStackTrace();
}

OID oOID = null;

try {
oOID = new OID(smiManager.parse("sysContact.0"));
} catch (ParseException e) {
e.printStackTrace();
}

System.out.println("OID: " + oOID.format());

}

}

Hi Maurice,

You simply need to load the MIB module(s). SmiManager.listModules() list
the modules
that are available in the repository. SmiManager.getLoadedModuleNames()
returns
the module names that are loaded and thus available for parsing.

Calling smiManager.loadModule("SNMPv2-MIB"); once before the first
"parse" will do
the trick.

Best regards,
Frank

Did the trick!!!

One more question, If I add more MIB files do they need to compiled or can they be read from the text? Looking at the repository they are binary, so that leads me to believe they are compiled.

Thanks,

Maurice
