[AGENT++] MibTable with IpAddress index

[Alex Agranov]

Hi,

I'm trying to create a MibTable that would represent ipAddrTable from MIB-2.
It has a single index of type IpAddress and a few fields.

My code looks roughly as follows:

const index_info indIpTable[1] = {
      { sNMP_SYNTAX_IPADDR, FALSE, 1, 1 } };

snIpTable::snIpTable():
    MibTable("1.3.6.1.2.1.4.20.1", indIpTable, 1)
{
    add_col(new MibLeaf("1", READONLY, new IpAddress("0.0.0.0")));          // ipAdEntAddr
    add_col(new MibLeaf("1", READONLY, new SnmpInt32(0)));                  // ipAdEntIfIndex
    add_col(new MibLeaf("1", READONLY, new IpAddress("255.255.255.255")));  // ipAdEntNetMask
    add_col(new MibLeaf("1", READONLY, new SnmpInt32(1)));                  // ipAdEntBcastAddr
    add_col(new MibLeaf("1", READONLY, new SnmpInt32(0xFFFF)));             // ipAdEntReasmMaxSize
}

void snIpTable::Update()
{
    mib->lock_mib();
    start_synch();

    clear();

    mib->unlock_mib();

    IpAddress ip("10.1.1.1");
    Oid index;
    index = ip;

    MibTableRow * row = add_row(index);
    if (row != NULL)
    {
         row->get_nth(0)->replace_value(new IpAddress("10.1.1.1"));
         row->get_nth(1)->replace_value(new SnmpInt32 (1));
         row->get_nth(2)->replace_value(new IpAddress("255.255.0.0"));
    }

    end_synch();
}

However for some reason it looks like AGENT++ doesn't understand that my table has an index. When I issue GET-NEXT on 1.3.6.1.2.1.4.20, my agent responds with 1.3.6.1.2.1.4.20.1.1 with no index.

What am I doing wrong?

Thank you in advance,
       Alex
