On the snmpd machine (fc6.mypc.com),
/usr/local/share/snmp/snmpd.conf is:
createUser -e 0x800000000102030405060708 test_MD5_AES
MD5 12345678 AES 87654321
trapsess -v 3 -u test_MD5_AES -l authPriv -a MD5 -A
12345678 -x AES -X 87654321 -e
0x800000000102030405060708 172.20.11.58

# snmptrap -v 3 -u test_MD5_AES -l authPriv -a MD5 -A
12345678 -x AES -X 87654321 -e
0x800000000102030405060708 172.20.11.58:162 100
..1.2.3.4.5.6.7.8

A trap is received on the snmptrapd machine
(172.20.11.58):
2007-12-10 09:28:29 fc6.mypc.com [UDP:
[172.20.11.245]:32802]:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (100)
0:00:01.00 SNMPv2-MIB::snmpTrapOID.0 = OID:
iso.2.3.4.5.6.7.8

However, a trap is not received on 172.20.11.58 when
restarting snmpd on fc6.mypc.com.
