RE: perl pass_persist getnext/getbulk - no end of MIB
Hi all, GETBULK always fills the returned buffer, so if your request does not completely fill the returned buffer, the agent will read further in the OID tree to fill the buffer. (please have a look at http://jmjmon.eu/LaSupervisionDeReseau/SNMP_Mon-V010.pdf page 74 and further) From my understanding, the problem does not come from GETBULK, either from snmptable that do not clean-up the overhead used to fill the buffer. When I use GETBULK I always (see same URL page 81 and 115) check that the last returned information is an answer to the requested OID, and not used-to-fill information.

Problem In GetBulk Handling
I am having a MIB which contain table structure and i have generate code
for that with the help of mib2c command
mib2c -c mib2c.create-dataset.conf IPsTable
It generates the two files IPsTable.c and IPsTable.h.
Actually when i send a command for snmpwalk
snmpwalk -v2c -c public localhost -Ci IPsTable
Its give an output thats states Error: OID not increasing
I have traced the log and got to know that we receive only the GET NEXT
request and the value of column field increases everytimes i got the
request.
case MODE_GETNEXT:
var = request-requestvb;
table_info = netsnmp_extract_table_info(request);
snmp_log(LOG_INFO,column : %d\n,table_info-colnum);
snmp_log(LOG_INFO,index : %d\n,*(table_info-indexes-val.integer));
if (table_info-colnum RESULT_COLUMN){
table_info-colnum=0;
return SNMP_ERR_NOERROR;
}
x=*(table_info-indexes-val.integer);
netsnmp_table_build_result(reginfo, requests,
table_info, ASN_INTEGER,
(u_char *) result,
sizeof(result));
break;
Problem arises when the value of column exceed from the number of column we
have in MIB's row and its keeps on increasing. I was not been able to
increment the value of index.
Is there any way so that i can reset the value of column and incement the
value of index (means pointing to next row) ?

NULL varbind prior to EndOfMib in GetBulk
Version 5.6.1.1, Windows platform... When doing a GetBulk to a proxied agent through snmpd (snmpd is the main agent, proxying to a non net-snmp implementation), snmpd returns an NULL varbind just before the EndOfMib. The last entry of the response has the last OID with its value, followed by the last OID with a NULL varbind, and finally the last OID with an EndOfMib. The error-index of the response is set to 1 with an error-status of noSuchName. This application issuing the request processes this as an error, and none of the OIDs are displayed. If I issue the GetBulk directly to the proxied agent, the extra NULL varbind is not there (just the last OID with its value followed by the last OID with and EndOfMib), and the error-index and error-status are 0, and the response is processed fine. Does anyone know if this is a bug in snmpd? I've seen some reports in the patch lists that suggest removing an extra NULL varbind prior to EndOfMib in various versions, both prior and after 5.6.1.1. I've downloaded the latest (5.7.2), and prior versions as well, but they all seem to operate the same. Thanks for your help... Mike -- Everyone hates slow websites. So do we.

So the exact same MIB code can be used within a Master agent (receiving requests via SNMP) or an AgentX sub-agent (receiving requests via AgentX). The processing of the request is essentially the same, so the MIB-specific code can effectively ignore the protocol stuff. That's handled by the main agent (or subagent) framework.

Re: GETBULK message change repetition
Hello,
my snmp application is created as a Dynamically Loadable Object. And i create
my tables with the mib2c tool. I get my data from an internal running deamon
which provides the specific data structures. The data call occurs within the
function 'module_get_next_data_point' below. The function which provides the
data from the deamon called 'get_modul_param_data'.
How can i reduce the traffic to my internal data on bulk requests, because on
huge data structures its takes a long time if value max_rep=10 on bulk messages.
netsnmp_variable_list *
moduleTable_get_next_data_point(void **my_loop_context,

*)*my_loop_context;
netsnmp_variable_list *idx = put_index_data;
if ( entry ) {

Yes - see the 'snmpbulkwalk(1)' and 'snmpbulkget(1)' man pages.
(though if you reduce this to one, it rather defeats the
point of using GETBULK rather than GETNEXT!)
within the snmpd.conf file?
No.
The max repetitions count is a feature of the client application.
You can't control this using agent configuration settings.

The purpose of the 'get_next_data_point' routine is simply to detect which is the appropriate row of the table for this particular request. It will typically work through *all* the rows of the table for each request, but is really only interested in the index values. There's no need to retrieve the actual data until the agent has determined which row is required. So I'd suggest you call get_modul_param_data() from the handler routine, rather than here. The iterator helper isn't the most efficient anyway. But if you're also retrieving a whole lot of unnecessary information every time through, then the performance is going to nosedive!

But i observe, if i make an snmptable request the data request is called 10 times, but i only have one data entry within my table. Can i change the max_rep value from the GETBULK message within the snmpd.conf file? Request: snmptable -v 2c -c public -Cf + 192.168.10.71 1.3.6.1.4.1.26958.25.3.3 Print statement from snmpd: Received SNMP packet(s) from UDP: [192.168.10.163]:58098-[192.168.10.71] GETBULK message, non-rep=0, max_rep=10 -- INDUSOL-MODULAR-INSPEKTOR-MIB::modOperStatus.37122 moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point moduleTable_get_next_data_point Sending 264 bytes to UDP: [192.168.10.163]:58098-[192.168.10.71] . .

(though if you reduce this to one, it rather defeats the point of using GETBULK rather than GETNEXT!) within the snmpd.conf file? No. The max repetitions count is a feature of the client application. You can't control this using agent configuration settings. Dave -- The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.

RE: Fails:: SNMPGetNext and GetBulk has the IP Address Index reversed in the request.
Hi,
After a bit of investigaton, the Getnext and bulkget calls go to the next
table, by adding a dummy colum entry with the below function call.
/*/
case COLUMN_TABLENOOP:
{
u_char x = '1';
netsnmp_table_build_result(reginfo, requests,
table_info, SNMP_NOSUCHOBJECT,
(u_char*) x,
sizeof(x));
break;
}
/*/
However the Snmpwalk does not retrive the next table column values, the call
reaches the column handler with the call as below, but the snmpwalk stops here,
and does not go further.
/*/
snmp_set_var_typed_value( request-requestvb, ASN_OCTET_STR,
(u_char*)table_entry-rName,
table_entry-Name_len);
/*/
Any ideas further??

Hi Dave,
I made the host to network order suggestion, and now it works for Get, GetNext
and BulkGet calls.
However iam facing a issues with Getnext/Bulk/Snmpwalk get calls going to the
next table, the bulk/walk requests are NOT going to next table, it traverses to
the beginning of the same table row.
Attached is the file. I really appreciate any help in this regard as this is a
blocking issue.
Thanks,
Anup

If you want a quick-n-dirty hack to get things working,
you could always tweak the vplexDirectorFETable_entry
(and similar) structure to include *two* fields for the
IP address - one held in host order and one in network
order.
Then use one for the index processing (in the get_first
and get_next routines), and the other in the handler
itself (for the column object).

The SMI type IpAddress is not an integer-based type.
It is a (four-octet) binary string, which holds the address
in network-byte order. See RFC 2758, section 7.1.5
You *might* be able to get away with treating it as an
integer in this way, but I certainly don't think you should
be returning it in host order.

Fails:: SNMPGetNext and GetBulk has the IP Address Index reversed in the request.
Hi All,
We are using NET-SNMP code for building an SNMP agent for servicing our MIB
file. The MIB file reports performance metrics for the hardware. The Table
entries in the MIB use IP Address as index.
The setup is as below:
-
NET-SNMP : net-snmp-5.3.0.1-25.25
OS: SLES 10 -- 32bit.
The problem iam facing is when I use the SNMPGet to retrieve the table entry it
Works. However the GetNext and GetBulk calls fail. I have used the
mib2c.iterate.conf to generate the code.
snmpget -v 2c -c public 127.0.0.1 1.3.6.1.4.1.1139.21.2.2.5.1.1.128.221.252.35
SNMPv2-SMI::enterprises.1139.21.2.2.5.1.1.128.221.252.35 = Counter64: 0
snmpgetnext -v 2c -c public 127.0.0.1

See RFC 2758, section 7.1.5 You *might* be able to get away with treating it as an integer in this way, but I certainly don't think you should be returning it in host order.

delegated and getbulk
List members, I am using the delegated flag in my extension of an snmp agent as described here: http://www.net-snmp.org/dev/agent/delayed__instance_8c-example.html It works well when I test it with snmpwalk, but fails when I use snmpbulkwalk. The first MIB object for which I use the delegated flag is fetched correctly, but then this object is repeated with the message: No more variables left in this MIB View (It is past the end of the MIB tree) This should not be the case. My handler is not called again after the first delegated object. I am not setting HANDLER_CAN_GETBULK I am checking the transaction id as recommended in the example above. Can you offer advice on the information given? Are there known limitations with get bulk and the delegated mechanism? -- Come build with us!

Getbulk maximum message size: any update?
I saw the problem with getbulk and maximum size message was reported back in june. I tried several versions of netsnmp including 5.4.1 and they all have this issue: when the package create is too big, not a smaller one is created but instead nothing is send at all. I tried to use HP openview in snmpv3 mode with netsnmpd and that completely fails, as the wizard to setup such a combination tries to get some data with getBulk requests. So I wonder: is there any update on this issue? anyone working on fixing it? Regards, Andreas - SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.

GETBULK returns only few rows of a table even if max-repetions is high

The response telegram is only 500 bytes, why the agent doesn't put all the rows in the response? Actually, I have an snmp agent that is connected to an AgentX subagent.

query about agentx - getbulk support..
Hi to all, I am using the netsnmp 5.2.1 version. This version is not supporting agentx protocol getbulk request. It makes a get-next request only to subagent. I checked the latest version ( 5.3 )also. That too also not supported the agentx getbulk. I look the developement plan on the net-snmp site. There is no plan for it to implement. Can you please let me know if there is any plan to implement getbulk of agentx protocol in near future? I know around 20% of code flow and data structure used by net-snmp. I have good knowledge about C. so can you tell me, how much time approx will it take if I try to implement it? and Please let me know also if there is any major issue or point where I should give more concentration while implementation.

In principle, the AgentX protocol can handle GETBULK requests, so these *ought* to be passed through to the subagent (which can then make this decision for each registration).

I wish to processing getBulk message which variable binding numbers are 44, and max repetitions are 2. Is This supported in net-snmp-5.1.1? Quite possibly - suck it and see. Try with a shorter varbind list and work upwards. Try with the full varbind list, but only 1 max-rep (i.e. the equivalent to GetNext). But I don't see why that shouldn't work.

Re: Getbulk
On more thing, GetBulk will start with the object ID A and ends with OID F. Am I right? or it traverses the whole MIB for which the related OID(s) are given? I'm not quite sure what you mean by that. The result of the GETBULK is simply a concatenation of the equivalent GETNEXT results. So using the same example: GETBULK (3, 5) A B C D E F might return RESPONSEA.1 B.1 C.1D.1 E.1 F.1D.2 E.2 F.2 D.3 E.3 F.3D.4 E.4 F.4 E.1 F.1 Z.0 (with the spacing being just for illustration of the GN equivalents) Note that the last repetition happened to run off the end of the table, so returned the lexically next entry in each case - either looping round to the start of the next column (E.1 F.1), or moving on to a completely unrelated object (Z.0) The agent doesn't know or care when this happens. A larger number of repetitions (e.g. GETNEXT 3, 7) would continue to look for the lexically next entries - regardless of whether they had already occurred earlier (E.2 E.3, F.2 F.3) or were completely unrelated to the main block of information (ZZ.0 ZZZ.0). Does that help, or are you even more confused? Dave --- This SF.Net email sponsored by Black Hat Briefings Training.

Re: Getbulk
Thanx a lot Dave for your kind help.. Tina - Original Message - From: Dave Shield [EMAIL PROTECTED] To: Tina Agarwal [EMAIL PROTECTED] Cc: net-snmp-users [EMAIL PROTECTED] Sent: Tuesday, July 13, 2004 3:26 PM Subject: Re: Getbulk Can anybody please explain GETBULK operation and its PDU in detail. I am not able to understand the function of non-repetitions and max-repeators. A GETBULK request is basically a series of GETNEXT requests, all bundled together into the one request. So a request such as GETBULK A B C D E F might expand to the equivalent of GETNEXT A B C GETNEXT D E F GETNEXT D.1 E.1 F.1 GETNEXT D.2 E.2 F.2 GETNEXT D.3 E.3 F.3 GETNEXT D.4 E.4 F.4 (or whatever the next objects happen to be). The max-repeaters value says how many times to repeat the D E F part of the request. The non-repetitions value says where to draw the line between the A B C part of the request (which is only done once) and the D E F request (which is done max-rep times). So the expansion above equates to non-reps = 3 (i.e. just one A B C row) max-reps = 5 (i.e. five D E F based rows) OK? Dave PS: Please - no HTML mail.
