RE: snmpwalk problem

Hi Elie,

In my comprehension of SNMP, I use snmpwalk to get all the" leaves" of a "branch" (and "under-branches"), and snmpget to get a specific "leave" of a branch.

So  snmpwalk localhost jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo.115 make not really sense, or am I wrong ?

I think you should either

Snmpwalk         localhost jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo
Or
Snmpget           localhost jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo.115

What do you expect to get returned by an
Snmpwalk localhost jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo.115

Best regards
JM

Objet : snmpwalk problem

Hi Team,

I am having a problem when retrieving the value of dynamic counters having an index greater than 114 as shown below on my Linux box

snmpwalk -v2c -c public localhost jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo.115
jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo.115: Unknown Object Identifier (Index out of range: 115 (name))

While if i perform the same command on an index lower than 115 the value is properly returned

snmpwalk -v2c -c public localhost jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo.111
JINNY-JAR-MIB::smppsir-dlvmo.111 = Counter32: 0

The related part of the MIB is the following:

If we run the snmpwalk to retrieve all the dlvmo counters values all the counters are displayed even the ones having an index higher than 114

snmpwalk -v2c -c public localhost jinny.generic.jar.smppsirTable.smppsirEntry.smppsir-dlvmo
JINNY-JAR-MIB::smppsir-dlvmo.1 = Counter32: 0
JINNY-JAR-MIB::smppsir-dlvmo.2 = Counter32: 0
JINNY-JAR-MIB::smppsir-dlvmo.3 = Counter32: 0
JINNY-JAR-MIB::smppsir-dlvmo.4 = Counter32: 0
JINNY-JAR-MIB::smppsir-dlvmo.5 = Counter32: 0

...
...

JINNY-JAR-MIB::smppsir-dlvmo.118 = Counter32: 0
JINNY-JAR-MIB::smppsir-dlvmo.119 = Counter32: 19136
JINNY-JAR-MIB::smppsir-dlvmo.120 = Counter32: 38025
JINNY-JAR-MIB::smppsir-dlvmo.121 = Counter32: 113871
JINNY-JAR-MIB::smppsir-dlvmo.122 = Counter32: 190952

...
...


Thus the problem is only when trying to retrieve dynamic counters with index greater than 114
The server has SNMP version 5.3.2.2

snmpwalk -V
NET-SNMP version: 5.3.2.2

Can you advice concerning this problem

Thanks in advance.
