SNMP TRAP meaning explanation


#1

Hello.

I set up SNMP TRAPs receiving from Mimosas to snmptrapd (Net-SNMP package) and snmptt (CentOS).
I set up Mimosa’s MIB-files import by snmptrapd:

/etc/snmp/snmp.conf:
mibdirs /usr/share/snmp/mibs/
mibs MIMOSA-NETWORKS-BASE-MIB:MIMOSA-NETWORKS-BFIVE-MIB

Now all is OK and I can receive TRAPs, but when I reboot Mimosa (soft reboot from UI), I see messages in snmptt’s debug log like this one:

Raw trap passed from snmptrapd:
1509037590
mimosa.local
UDP: [10.20.20.19]:34945->[10.0.0.101]:162
SNMPv2-MIB::sysUpTime.0 0:0:01:10.95
SNMPv2-MIB::snmpTrapOID.0 MIMOSA-NETWORKS-BASE-MIB::mimosaMgmt.2.0.0
IF-MIB::ifIndex.1 3
SNMPv2-SMI::snmpModules.18.1.3.0 10.20.20.19
SNMPv2-SMI::snmpModules.18.1.4.0 "mimosa"
SNMPv2-MIB::snmpTrapEnterprise.0 MIMOSA-NETWORKS-BASE-MIB::mimosaMgmt.2

It is because there is no defenition in MIB-file for MIMOSA-NETWORKS-BASE-MIB::mimosaMgmt.2:

/usr/share/snmp/mibs/MIMOSA-MIB.txt:

mimosaTrap                    OBJECT IDENTIFIER ::= { mimosaMgmt 0 }
mimosaMib                     OBJECT IDENTIFIER ::= { mimosaMgmt 1 }
mimosaMIBGroups               OBJECT IDENTIFIER ::= { mimosaMgmt 3 }
mimosaConformanceGroup        OBJECT IDENTIFIER ::= { mimosaMgmt 4 }

Can you please explain the meaning of this entity and update MIB-file?

PS:
Enother messages are IF-MIB::linkUp / IF-MIB::linkDown / SNMPv2-MIB::warmStart and some times SNMPv2-MIB::coldStart
