>> How the SNMP read(differentiate) the different indexes in the OID ?
In this particular case 3 of them of are of fixed length, so SNMP specs tell
how to interpret the indexes. Ip address is in dotted format, so there will be
3 dots for ip. In case variable length( e.g name), it needs to prepended with
number of characters in the index. E.g
Index 1: name1 (varaiable length)
Index2: new-name2 (varaiable length)
Now the index for any ROW for the table will be
5.ASCII(n).ASCII(a).ASCII(m).ASCII(e).ASCII(1).9.
ASCII(n).ASCII(e).ASCII(w).ASCII(-).ASCII(n).ASCII(a).ASCII(m).ASCII(e).ASCII(2)
5 here is length of "name1" and 9 is length of "new-name2"
For fixed length string or IP Addresses, lndeth doesn't have to pre-pended
>> How net-snmp code find out this object having 4 indexes ?
To use net-snmp code needs to know the MIB, then only net-snmp can handle the
request else it will respond back with "Unkown OID". Somebody has to compile
MIB and fill the needed places to net-snmp to accept a OID
Is there any net-snmp function available(Or similar which I can modify and use)
which will separate out the different Indexes
