Some clients are having problems with the OID for SNMP v1 Traps, SNMP v2c traps
work fine.
The trap OID is defined as: 1.3.6.1.4.1.9804.3.1.1.0.1
Some clients appear to see the v1 trap as as: 1.3.6.1.4.1.9804.3.1.1.1
Net-SNMP receives the v1 and v2c trap just fine.
A partial snmptranslate:
"lhnNsmDevices"
"1.3.6.1.4.1.9804.3.1.1"
"lhnNsmEvents"
"1.3.6.1.4.1.9804.3.1.1.0"
"lhnNsmNotificationGeneric" "1.3.6.1.4.1.9804.3.1.1.0.1"
The MIB has:
lhnNsmNotificationGeneric NOTIFICATION-TYPE
OBJECTS {
message,
messageTime
}
STATUS current
DESCRIPTION "A generic system event was generated."
::= { lhnNsmEvents 1 }
snmptrapd from Net-SNMP 5.4.2.1 on Ubuntu logs the trap as:
2010-07-13 16:27:28 nsm185-41.lhn.com [10.0.62.41] (via UDP:
[10.0.62.41]:54066->[10.0.10.25]) TRAP, SNMP v1, community public
LEFTHAND-NETWORKS-NSM-MIB::lhnNsmDevices Enterprise Specific
Trap (LEFTHAND-NETWORKS-NSM-NOTIFICATION-MIB::lhnNsmNotificationGeneric)
Uptime: 0:05:14.81
LEFTHAND-NETWORKS-NSM-NOTIFICATION-MIB::message.6 = STRING:
Test Trap LEFTHAND-NETWORKS-NSM-NOTIFICATION-MIB::messageTime.6 =
STRING: 2010-7-13,22:27:29.0,+0:0
The iReasoning MIB Browser shows the v1 trap as:
Specific: 1; .1.3.6.1.4.1.9804.3.1.1 10.0.62.41
2010-07-13 16:26:34
but gets the SNMP v2c trap just fine as:
trapOID: .1.3.6.1.4.1.9804.3.1.1.0.1 10.0.62.41 2010-07-13
17:19:00
Wireshark shows:
version: version-1
enterprise: 1.3.6.1.4.1.9804.3.1.1 (SNMPv2-SMI::enterprises.9804.3.1.1)
generic-trap: enterpriseSpecific (6)
specific-trap: 1
The agent sends both the SNMP v1 and v2c traps using: "send_v2trap(&trapVar)"
The agent sending the traps is running on Net-SNMP 5.3.2.2 on RHEL 5.
snmptranslate and smilint do not show any errors or warnings.
Is there something I'm doing wrong in how the trap is sent or in the MIB?
Thanks for your help,
Scott
