NetXMS Support Forum

It was an IOS version issue. After upgrade it's gone.

ok, I figured out why it's inconsistent.
Because netxms does not do correct mapping of lldp port id to ifindex. Here is a quote from my question on cisco support forum (https://supportforums.cisco.com/discussion/13153696/snmp-lldp-port-id-ifindex-mapping-4500x):

QuoteWe have 2 WS-C4500X-16 SFP+ bundled as VSS running cat4500e-universalk9.SPA.03.05.03.E.152-1.E3.

Try to poll lldp topology from it and can't figure out how to map lldp port id to the ifindex of the interface. For example:

ifIndex list:

.1.3.6.1.2.1.2.2.1.1.1 [INTEGER] = 1
.1.3.6.1.2.1.2.2.1.1.344 [INTEGER] = 344

LLDP Neighbors (lldpRemChassisId):

.1.0.8802.1.1.2.1.4.1.1.5.0.11.2 [Hex-STRING] = A8 F9 4B 95 C7 00
.1.0.8802.1.1.2.1.4.1.1.5.0.12.4 [Hex-STRING] = A8 F9 4B E8 05 C0
.1.0.8802.1.1.2.1.4.1.1.5.0.1291.1 [Hex-STRING] = A8 F9 4B 95 C7 00
.1.0.8802.1.1.2.1.4.1.1.5.0.1292.3 [Hex-STRING] = A8 F9 4B E8 05 C0

Local port naming (lldpLocPortId):

.1.0.8802.1.1.2.1.3.7.1.3.11 [STRING] = Te1/1/11
.1.0.8802.1.1.2.1.3.7.1.3.12 [STRING] = Te1/1/12
.1.0.8802.1.1.2.1.3.7.1.3.1291 [STRING] = Te2/1/11
.1.0.8802.1.1.2.1.3.7.1.3.1292 [STRING] = Te2/1/12

So we have lldp ports 11,12,1291,1292. LLDP MIB says:

    A port number has no mandatory relationship to an
    InterfaceIndex object (of the interfaces MIB, IETF RFC 2863).
    If the LLDP agent is a IEEE 802.1D, IEEE 802.1Q bridge, the
    LldpPortNumber will have the same value as the dot1dBasePort
    object (defined in IETF RFC 1493) associated corresponding
    bridge port.  If the system hosting LLDP agent is not an
    IEEE 802.1D or an IEEE 802.1Q bridge, the LldpPortNumber
    will have the same value as the corresponding interface's
    InterfaceIndex object.

And here is a dot1dBasePort and dot1dBasePortIfIndex poll:

.1.3.6.1.2.1.17.1.4.1.1.2561 [INTEGER] = 2561
.1.3.6.1.2.1.17.1.4.1.1.2562 [INTEGER] = 2562
.1.3.6.1.2.1.17.1.4.1.1.2563 [INTEGER] = 2563
.1.3.6.1.2.1.17.1.4.1.1.2570 [INTEGER] = 2570
.1.3.6.1.2.1.17.1.4.1.1.2623 [INTEGER] = 2623
.1.3.6.1.2.1.17.1.4.1.1.2624 [INTEGER] = 2624
.1.3.6.1.2.1.17.1.4.1.1.2651 [INTEGER] = 2651
.1.3.6.1.2.1.17.1.4.1.1.2652 [INTEGER] = 2652

.1.3.6.1.2.1.17.1.4.1.2.2561 [INTEGER] = 41
.1.3.6.1.2.1.17.1.4.1.2.2562 [INTEGER] = 42
.1.3.6.1.2.1.17.1.4.1.2.2563 [INTEGER] = 43
.1.3.6.1.2.1.17.1.4.1.2.2570 [INTEGER] = 45
.1.3.6.1.2.1.17.1.4.1.2.2623 [INTEGER] = 46
.1.3.6.1.2.1.17.1.4.1.2.2624 [INTEGER] = 47
.1.3.6.1.2.1.17.1.4.1.2.2651 [INTEGER] = 337
.1.3.6.1.2.1.17.1.4.1.2.2652 [INTEGER] = 338

Not only the output does not map lldp port to bridge port, but the bridge ports does not contain ALL ports. 41-47, 337,338 are ifIndexes of Portchannels and not individual physical ports. Does any one know something about this issue, maybe newer software?

And today I found that one can poll the mapping for all ports by snmpwalk in context '0'. For example,

Quotendd# nxsnmpwalk -c public@0 172.16.x.x .1.3.6.1.2.1.17.1.4.1.2

Unfortunately, this context '0' is not universal across cisco devices. I have several other cisco devices that does not even respond to '0' context requests. So this must be implemented as a hack or maybe move that part to device driver.

Still can't figure out why this happening with this switch. Put some logs here, maybe someone take a look at this.
This is what happen when  I do topology poll on both sides of the peer connection.

Где-то я на форуме находил, что можно как-то консоль запустить из eclipse сразу. Есть такая возможность?

установил draw2d. в проекты импортнул папку netxms-eclipse, org.netxms.nebula.widgets.gallery, client.
на текущий момент 3063 ошибки:
1. судя по всему не знает откуда взять import org.netxms.ui.eclipse.objectbrowser.api.SubtreeType;
2. много ошибок вида "'for each' statements are only available if source level is 1.5 or greater"
3. Cannot switch on a value of type Integer. Only convertible int values or enum variables are permitted   
4. Incompatible conditional operand types Integer and int

Пробую еще. Из файла eclipse_addons.txt:

QuoteDraw2D: http://download.eclipse.org/tools/gef/updates/milestones/

- по этой ссылке нету Draw2D. Там есть куча групп GEF Common, GEF DOT, GEF GRAPH, GEF LAYOUT и тд. Draw2D среди них нет. 

Попробую еще разок установить.
Пытаюсь установить на win7 x64.

If I do topology poll on the 4500x the peers in interface table disappear, if I do topology poll on the disappeared peer the interface table is populated again and is correct.

Forced topology poll shows me that it found 10 connections but in the following list there are only 8 connections.

I just noted that in the event log at 11:40 new peers appeared again and interface table showed correct peer information, but in several minutes (around 7-8 minutes) some records in the interface table just disappeared and event log does not show any information about that.

I have 2 4500x switches which are coupled as one logical unit with VSS technologie.
And in the event log I see that this switch keeps rediscovering 'new' (in fact old) peers every 30 minutes like so:

Maybe netxms is getting confused by the fact that this switch is a logical stack of 2 switches that are connected by te1/0/47, te1/0/48 on both switches.

The patch is working fine. Thanks.

I maybe wrong, but here is my thoughts about this.
ifIndex is 0 'cause ifIndexFromPort function return 0.
Take a look at fdb.cpp:

void ForwardingDatabase::addEntry(FDB_ENTRY *entry)
{
// Check for duplicate
for(int i = 0; i < m_fdbSize; i++)
if (!memcmp(m_fdb[i].macAddr, entry->macAddr, MAC_ADDR_LENGTH))
{
memcpy(&m_fdb[i], entry, sizeof(FDB_ENTRY));
m_fdb[i].ifIndex = ifIndexFromPort(entry->port);                        <--- here
return;
}

if (m_fdbSize == m_fdbAllocated)
{
m_fdbAllocated += 32;
m_fdb = (FDB_ENTRY *)realloc(m_fdb, sizeof(FDB_ENTRY) * m_fdbAllocated);
}
memcpy(&m_fdb[m_fdbSize], entry, sizeof(FDB_ENTRY));
m_fdb[m_fdbSize].ifIndex = ifIndexFromPort(entry->port);                             <--- and here
m_fdbSize++;
}


UINT32 ForwardingDatabase::ifIndexFromPort(UINT32 port)
{
for(int i = 0; i < m_pmSize; i++)
if (m_portMap[i].port == port)                   <---so it seems like portMap structure does not contain required port, why?
return m_portMap[i].ifIndex;
return 0;
}


portMap structure populated by "addPortMapping" function which is called from Dot1dPortTableHandler callback, and which is called from

ForwardingDatabase *GetSwitchForwardingDatabase(Node *node)
{
if (!node->isBridge())
return NULL;

ForwardingDatabase *fdb = new ForwardingDatabase(node->getId());
node->callSnmpEnumerate(_T(".1.3.6.1.2.1.17.1.4.1.2"), Dot1dPortTableHandler, fdb);              <---- here
node->callSnmpEnumerate(_T(".1.3.6.1.2.1.17.7.1.2.2.1.2"), Dot1qTpFdbHandler, fdb);


But this snmpenumerate request must also be vlan-context-aware as with followed code with mac address table request.

Here is a sample snmpwalks to the cisco switch:
admin@netxms:/home/admin# nxsnmpwalk -c community@10 172.x.x.x .1.3.6.1.2.1.17.1.4.1.2
.1.3.6.1.2.1.17.1.4.1.2.7 [INTEGER]: 7
.1.3.6.1.2.1.17.1.4.1.2.31 [INTEGER]: 31
.1.3.6.1.2.1.17.1.4.1.2.47 [INTEGER]: 43
.1.3.6.1.2.1.17.1.4.1.2.48 [INTEGER]: 44
.1.3.6.1.2.1.17.1.4.1.2.65 [INTEGER]: 53
admin@netxms:/home/admin# nxsnmpwalk -c community@11 172.x.x.x .1.3.6.1.2.1.17.1.4.1.2
.1.3.6.1.2.1.17.1.4.1.2.65 [INTEGER]: 53

Tatjana,
Will post here 'cause I have the same issue.
I have a cisco switch 3550 (which is snmp-enabled) and sensor1 (disabled all polls except icmp) with mac 00:a2:19:60:00:00 that is connected to fa0/48 port (access port with vlan 10). FDB table for 3550 is showing me this:
00:a2:19:60:00:00    48    [0]     10      sensor1     dynamic
so FDB seems correct however I don't know what is 'interface' = 0 and in the interface tab of the object viewer netxms does not show any peer nodes, but it has to be fa0/48    .....     sensor1    192.168.x.x    FDB.

I attached requested OIDs.
