Net::Snmp->session->get_table() data missing

sherman has asked for the wisdom of the Perl Monks concerning the following question:

Not sure if anyone raised this before, please point me to the right thread if someone has answer this before.

I found Net::Snmp->get_table() failed to return all data. Net::Snmp version: 6.0.1.

I tried to retrieve a nic usagge on a window box but one of interface was not included on get_table() result the debug shows the missing PDU was retrieved from the window box, but not included in the return result object for some reason

debug: 965 Net::SNMP::PDU::_process_var_bind_list(): { 1.3.6.1.2.1.2.2.1.2.19 => OCTET STRING: Microsoft ISATAP Adapter #4 }

debug: 1506 Net::SNMP::Message::_process_octet_string(): not translating OCTET STRING, all octets are allowed in a DisplayString

debug: 965 Net::SNMP::PDU::_process_var_bind_list(): { 1.3.6.1.2.1.2.2.1.2.20 => OCTET STRING: GES EX (Giga Ethernet System) Express PCI Adapter (NDIS) }

debug: 1506 Net::SNMP::Message::_process_octet_string(): not translating OCTET STRING, all octets are allowed in a DisplayString

debug: 965 Net::SNMP::PDU::_process_var_bind_list(): { 1.3.6.1.2.1.2.2.1.2.21 => OCTET STRING: Microsoft ISATAP Adapter #5 }

debug: 1506 Net::SNMP::Message::_process_octet_string(): not translating OCTET STRING, all octets are allowed in a DisplayString

debug: 965 Net::SNMP::PDU::_process_var_bind_list(): { 1.3.6.1.2.1.2.2.1.2.22 => OCTET STRING: GES EX (Giga Ethernet System) Express PCI Adapter (NDIS) #2 }

debug: 965 Net::SNMP::PDU::_process_var_bind_list(): { 1.3.6.1.2.1.2.2.1.2.23 => OCTET STRING: Microsoft ISATAP Adapter #6 }

Data Return by Net::Snmp->session->get_table()

OID : 1.3.6.1.2.1.2.2.1.2.19, Desc : Microsoft ISATAP Adapter #4

List : Microsoft ISATAP Adapter #4

OID : 1.3.6.1.2.1.2.2.1.2.22, Desc : GES EX (Giga Ethernet System) Express PCI Adapter (NDIS) #2 List : GES EX (Giga Ethernet System) Express PCI Adapter (NDIS) #2

The OID: 1.3.6.1.2.1.2.2.1.2.20 was discarded during the process for some reason

Does anyone has idea how I get the missing PDU return properly?

Thanks

Sherman

Hi Sherman, welcome to the monastery. If you format your post according to the guidelines, including putting any code between `<code> ... </code>` tags, there'll be a much better chance that someone will be able to help you. My first question to you is, have you read all the documentation for Net::SNMP ? Remember: Ne dederis in spiritu molere illegitimi!	[reply] [d/l] [select]

Hi Have you tried to get the table value from command line using snmpwalk utility ? Does it return some data ? Please post the code also which is not functioning properly ? Code Snippet of get_table() `my $ip = "your_ip_device"; my $snmpCommunity = "your_snmp_community"; my $oid = "oid_you_want_to_poll"; my $port = "you_snmp_port"; # By default its 161 my ($session, $error) = Net::SNMP->session( -hostname => "$ip", -community => "$snmpCo +mmunity", -timeout => "30", -version => "2", -port => "$port"); if(!defined($session)){ printf("ERROR : %s.\n", $error); exit 1; } my $response = $session->get_table($oid);` [download] Do you want to varbind the variable using SNMPTRAP ?
