Why is the community name not available with SNMPV3 traps.
One may argue that you shouldn't be using security 'passwords' for
organizing your traps, but we allow it for SNMPV1/2. It's only for
receiving traps anyways.

Can i use the agent id from V3? If yes, how ?


Details:


SNMPv2
------

With SNMPv2 i have into the database my filled community, which we use as
unque key for mapping our trap destination.

snmptrap -v 2c -c community_snmp crinaea06:162 "" ucdStart
sysContact.0 s
"APE-TEST-SNMPTTv2c-TRAP"

1221657977
crinaea06
UDP: [10.6.101.78]:50309
.1.3.6.1.2.1.1.3.0 76:22:59:31.44
.1.3.6.1.6.3.1.1.4.1.0 .1.3.6.1.4.1.2021.251.1 .1.3.6.1.2.1.1.4.0
APE-TEST-SNMPTTv2c-TRAP


SNMPv3
------

With SNMPv3 we have into the database my not filled in with the community,
and the engine id as unique key for mapping our trap destination is not
pressend.

snmptrap -v 3 -u password_snmp -a MD5 -A password_snmp -x DES -X
password_snmp -l authPriv -e 0x0102030405 crinaea06:162 "" ucdStart
sysContact.0 s "APE-TEST-SNMPTTv3-TRAP"

APE-TEST-SNMPTTv3-TRAP

What is the equivalent in SNMPv3 within SNMPTT for creating the same
possibility then we have with the community from SNMPv2 for making an
unique mapping.

For some reason Net-SNMP doesn't let you use the community string with
SNMP V3 traps when using the traphandler.

I remember discussing this with some of the other Net-SNMP developers
but I'm not sure where it was. It may have been inside of a bug or
patch report but I can't find it.

I suggest you email Net-SNMP-Users and ask why the community name isn't
available with SNMPV3 traps. One may argue that you shouldn't be using
security 'passwords' for organizing your traps, but we allow it for
SNMPV1/2. It's only for receiving traps anyways.
