Re: [Mibble-users] parse TRAP-TYPE

[Tim Schöndorfer]

Ok i have found a solution :

Mib mib = loader.load(mibfiles.get(i));

System.out.println(mib.getSymbolByOid("1.3.6.1.2.1.2.2.1.7.7").getName());

MibValueSymbol sy = mib.getSymbolByOid("1.3.6.1.2.1.2.2.1.7.7");

SnmpObjectType sno = (SnmpObjectType) sy.getType();

System.out.println(sno.getSyntax());

if(sno.getSyntax() instanceof IntegerType){

IntegerType in = (IntegerType) sno.getSyntax();

MibValueSymbol[] syin = in.getAllSymbols();

for(int j = 0; j<syin.length;j++){

if(syin[j].getValue().toString().contains("1")){

System.out.println(syin[j].getName());

}

}

}

i think i'm starting to have understood Mibble

Thanks,

Tim

Thank you for the fast answer.

 

I solved it with the iterator.

But now i have another problem with the use of mibble.

Some integer values have a specific meaning for example 1.3.6.1.2.1.2.2.1.8 (ifOperStatus) when i receive one thats mean its up , 2 for down and so on

How can i get this meanings from the mib ?

I try to get the MibValueSymbol with this function --> MibValueSymbol sy = mib.getSymbolByOid("1.3.6.1.2.1.2.2.1.8");

How can i search in this mibvaluesymbol for the valuedefintions ?

 

Thanks a lot,

 

Tim

Yes, the TRAP-TYPE is parsed and accessible in Mibble. But in SMIv1, the traps aren't assigned to OIDs, so they are a bit more tricky to find. Basically you search for them with their numeric value ("1", "2", etc):
 

   mib.getSymbolByValue("1")

 

Or you can find the traps by iterating over all MibValueSymbol instances, filtering out the symbols with a type that is instanceof SnmpTrapType.
 

You can always inspect the parsed results by using the MibblePrinter utility (which pretty-prints the parsed MIB). A small example for RFC1382-MIB:

#> bin/MibblePrinter.sh src/mibs/ietf/RFC1382-MIB

x25Restart TRAP-TYPE
    ENTERPRISE      x25
    VARIABLES       { x25OperIndex }
    DESCRIPTION
            "This trap means the X.25 PLE sent or
            received a restart packet.  The restart that
            brings up the link should not send a
            x25Restart trap so the interface should send
            a linkUp trap.  Sending this trap means the
            agent does not send a linkDown and linkUp
            trap."

Hello,

 

I writing a snmp-trapreceiver with mibble. But mibble can not find the trap in the MIB-file (i think thats because the trap isnt a object-type, it is save in the mib as a TRAP-TYPE).

I spending much time on search for a solution, but i didnt find a way to parse the mib file and get the trap description or the trap name. The traps are snmp v1 traps so i get the enterprise oid and a specific number from the trap pdu and i try to parse the mib file with "Mib mib = MibLoader.load(Mib-File) and mib.getSymbolByOid(EnterpriseOid+.0.+specificNumber);" but this doenst work(it only works with normal OIDs). So how can i parse a mib-file with mibble to get the TRAP-TYPEs?

 

Thanks, Tim Schöndorfer
