Hi Dave, Thanks again for the response.

Re: array-user snmpbulkwalk worked for a table not entire mib
Hi Dave, Thanks again. Robert may be looking into it, although he may not have been actually able to reproduce it yet. I am just not sure if this has to do with array-user or not, it may have been something I have done. If I put the non-repeater value to anything 1 and higher it works fine. I just have to be able to justify why someone would have to set that, and I haven't yet gotten there. As for individual bulkgets, I suppose I am not quite sure what I will describe here makes sense(most likely it does not), but on a snmpwalk I used a -Cp to get the number of variables. Then to get the entire table with a snmpbulkget I set -Cr to that number(33). It worked fine, no "no more variables". When I increased the number to 34, again it works fine, got a scalar object that is in the next object group as well. But, when I increased it to 35, that is when I saw the "no more variables". The second entry in the object group is the next table. It is interesting, but unfortunately tells me nothing. - John --- On Fri 05/27, Dave Shield < [EMAIL PROTECTED] > wrote: From: Dave Shield [mailto: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: net-snmp-users@lists.sourceforge.net Date: Fri, 27 May 2005 09:04:35 +0100 Subject: Re: array-user snmpbulkwalk worked for a table not entire mib On Thu, 2005-05-26 at 19:13, [EMAIL PROTECTED] wrote:>Could you possibly explain why an snmpbulkwalk command> would work on my MIB when the non-repeater value is set to 1> and fail when not set at all?Not really, no.I thought Robert was looking into that?I was just commenting on the higher-level issues.> As my original email specified, if a snmpbulkwalk is done on one of> my tables I get: No more variables left in this MIB View (It is past> the end of the MIB tree) If the -Cn1 is set then no such problem.What if you try with '-Cn2' ?Does it make any difference if there's an odd or even numberof rows in the table?It might also be worth trying with 'snmpbulkget' ratherthan 'snmpbulkwalk', and manually walking a singlecolumn of the table.DaveJoin Excite! - http://www.excite.comThe most personalized portal on the Web!
Re: array-user snmpbulkwalk worked for a table not entire mib
Hi Dave, Thanks. I did the repeater(repetition) value experimentation based on Roberts suggestion. Just want to be sure, but does setting the non-repeater value to 1 have a similar functional effect to the a command as the max-repetitions? i.e. Is this something that I cannot ask an SNMP manager to do as it is non-standard or maybe it does not provide the expected GetBulk optimization effect? - John --- On Thu 05/26, Dave Shield < [EMAIL PROTECTED] > wrote: From: Dave Shield [mailto: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: net-snmp-users@lists.sourceforge.net Date: Thu, 26 May 2005 10:34:21 +0100 Subject: Re: array-user snmpbulkwalk worked for a table not entire mib On Tue, 2005-05-24 at 19:11, [EMAIL PROTECTED] wrote:> Also, changing the max-repeater to 1.

No - the two fields have completely different purposes. A single GetBulk request is basically equivalent to one GetNext request (with non-repeater varbinds) followed by max-repetitions GetNext requests (each containing the remaining varbinds). So GetBulk( non=2, max=3) A B C D E is equivalent to: GetNext A B GetNext C D E GetNext C' D' E' GetNext C D E If max=1, then this becomes GetNext A B GetNext C D E which is exactly equivalent to GetNext A B C D E It's the max-repetitions field that really distinguishes GetBulk from GetNext requests.

Re: array-user snmpbulkwalk worked for a table not entire mib
Hi Dave, Thanks again. Could you possibly explain why an snmpbulkwalk command would work on my MIB when the non-repeater value is set to 1 and fail when not set at all? As my original email specified, if a snmpbulkwalk is done on one of my tables I get: No more variables left in this MIB View (It is past the end of the MIB tree) If the -Cn1 is set then no such problem. The real problem is trying to walk multiple tables in one snmpbulkwalk, as it can't go from one to another if it receives the "No more" after the first. - John --- On Thu 05/26, Dave Shield < [EMAIL PROTECTED] > wrote: From: Dave Shield [mailto: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: net-snmp-users@lists.sourceforge.net Date: Thu, 26 May 2005 16:11:47 +0100 Subject: Re: array-user snmpbulkwalk worked for a table not entire mib On Thu, 2005-05-26 at 15:48, [EMAIL PROTECTED] wrote:> does setting the > non-repeater value to 1 have a similar functional effect to the a > command as the max-repetitions?No - the two fields have completely different purposes.A single GetBulk request is basically equivalent to oneGetNext request (with "non-repeater" varbinds) followedby "max-repetitions" GetNext requests (each containingthe remaining varbinds).So GetBulk( non=2, max=3) A B C D Eis equivalent to: GetNext A B GetNext C D E GetNext C' D' E' GetNext C" D" E"If max=1, then this becomes GetNext A B GetNext C D Ewhich is exactly equivalent to GetNext A B C D EIt's the max-repetitions field that really distinguishesGetBulk from GetNext requests.

Re: array-user snmpbulkwalk worked for a table not entire mib
When setting the non-repeater value to 1 and up, it seemed to avoid the problem. Also, changing the max-repeater to 1. Is changing these values to make a bulkwalk work an acceptable practice?
