command snmptrap (a command line interface) using SNMP v2

Hello
a) I concatenated our exchanged mails in the end
b) Traps are always send to a single client (10.140.20.69)
c) "and so on..." means: elements/parameters in SNMP v2 protocol e.g.. As in an example
time 14:02:55.912422
source 10.93.112.14.32771
destination 10.140.20.69.162
.1.3.6.1.2.1.1.3(sysUpTime ) 1246333
.1.3.6.1.6.3.1.1.4.1(snmpTrapOID) .1.3.6.1.4.1.193.109.2.0.3(elnLinkUp)
.1.3.6.1.4.1.193.72.500.1.1.0 (param1...managedObjectClass) EAN
.1.3.6.1.4.1.193.72.500.1.2.0 (param2...managedObjectInstance) EAN=10.93.112.14,EFN324xf,Port=1002.0.12
.1.3.6.1.4.1.193.72.500.1.3.0 (param3...sequenceNumber) 24
.1.3.6.1.4.1.193.72.500.1.4.0 (param4...perceivedSeverity) 1
.1.3.6.1.4.1.193.72.500.1.5.0 (param5...eventTime) 07_dc_01_11_0d_02_37_59_2b_00_00
.1.3.6.1.4.1.193.72.500.1.6.0 (param6...eventTypePem) 2
.1.3.6.1.4.1.193.72.500.1.7.0 (param7...probableCause) 65
d) client (10.140.20.69) is defined to work with SNMP v2 protocol
e) Reading FAQ "How can I get the agent to send an SNMPv1 (or SNMPv2c) trap?" and an answer there:
"....It doesn't make any difference whether you use the v1-style API call 'send_easy_trap()' or the v2-style 'send_v2trap()'.
What matters is the directive(s) in the snmpd.conf file.
If this file contains 'trapsink', then the agent will send an SNMPv1 trap. If this file contains 'trap2sink', then the
agent will send an SNMPv2c trap. ...."
open/give to me the possibility to find the way how to solve my idea/problem.

- snmptrap does not communicate with the agent, it sends traps directly to the
specified host.
- are you always sending traps to a single client? Or does "and so on..." mean
that you need to send the same trap to multiple clients?

This is true for all v2/v3 traps. We don't support spoofing the source address in the udp packet.
Why not use v1 traps, which contain the 'agent' in the PDU itself (which can easily be set via snmptrap)?

Hello Mr.Robert Story
Here is more clearly written my problem...
I'd like to use the command snmptrap to reach following scenarios
Agent Client
(10.140.20.71) (10.140.20.69)
| |
snmptrap * | |
=========> | |
| Notification (SNMP v2) |

| destination (10.140.20.69) |
| and so on... |
| |
| |
* snmptrap -v 2c [COMMON OPTIONS] [-Ci] uptime trap-oid [OID TYPE VALUE]...
Note: there is no possibility to generate wanted source with this command,
i.e. Agent address (10.140.20.71) will be always in source
** One of IP address from FTTH (fiber to the home) network
e.g. SmartMetro (10.93.50.111) or ECN (10.93.112.3)
Note: in the source should not be Agent address (10.140.20.71)

What is actually generating the traps? You said you wanted a command line interface to send traps, so I still don't understand where the agent comes in, and why you can't simply use snmptrap to simulate the traps?

Why do you want to use snmpd, instead of using snmptrap?

Dear
I'd like to work with net-snmp agent , i.e. using it to send traps to the snmp manager with a command line interface on Linux
Idea is to simulate expected traps from FTTH (fiber to the home) network build with different nodes (SmartMetro, LG Ericsson and Ericsson family - ENC/EFN).
SNMP protocol is version 2
Reading available documentations (Net-SNMP) following variants/possibilities are points where I didn't find my solution:
a) snmptrap -v 1 [COMMON OPTIONS] [-Ci] destination enterprise-oid agent generic-trap specific-trap uptime [OID TYPE VALUE]
b) snmptrap -v2c [COMMON OPTIONS] [-Ci] uptime trap-oid [OID TYPE VALUE]...
c) mapping/trap generator "send_easy_trap" vs "send_v2trap"
Could you help me with an idea how to reach this task ?
