Hi Folks,
Can anybody tell me how can I check version(snmp2c/3) of received traps by
'snmptrapd' ?
Settings:
runnging snmpd, snmptrapd and snmptrap on same system (localhost)
*CASE 1: SNMPv1*
send snmpv1 trap --->
snmptrap -v 1 -c public localhost .1.3.6.1.4.1.8072.2.3.1 localhost 2 0 ""
>.1.3.6.1.4.1.8072.2.1.1 i 123
snmpv1 trap received by snmptrapd --->
2014-12-24 11:17:06 localhost [127.0.0.1] (via UDP:
[127.0.0.1]:51079->[127.0.0.1]) TRAP, >SNMP v1, community public
iso.3.6.1.4.1.8072.2.3.1 Link Down Trap (0) Uptime: 1:46:24.34
iso.3.6.1.4.1.8072.2.1.1 = INTEGER: 123
*CASE 2: SNMPv2c*
send snmpv2c trap --->
snmptrap -v 2c -c public localhost 69 .1.3.6.1.4.1.8072.2.3.1
.1.3.6.1.4.1.8072.2.1.1 i 123
snmpv2c trap received by snmptrapd --->
2014-12-24 11:28:52 localhost [UDP: [127.0.0.1]:35333->[127.0.0.1]]:

OID: >iso.3.6.1.4.1.8072.2.3.1 iso.3.6.1.4.1.8072.2.1.1 = INTEGER:
123 <--------------------- log A
*CASE 3: SNMPv3*
send snmpv3 trap --->
snmptrap -v 3 -n "" -a SHA -A mypassword -x AES -X mypassword -l authPriv
-u traptest -e >0x80001f880300b0ae000000 localhost 69

snmpv3 trap received by snmptrapd --->
2014-12-24 11:10:49 localhost [UDP: [127.0.0.1]:35306->[127.0.0.1]]:
iso.3.6.1.2.1.1.3.0 = Timeticks: (69) 0:00:00.69 iso.3.6.1.6.3.1.1.4.1.0 =
OID: >iso.3.6.1.4.1.8072.2.3.1 iso.3.6.1.4.1.8072.2.1.1 = INTEGER:
123 <---------------------------- log B
Question: In case 2 and 3 , trap received by snmptrapd (i.e log A and log
B) is same. How to make out trap version of the traps been received by
snmptrapd?
Thank you,
Pushpa
