+Multiple SNMP USM users
++++++++++++++++++++++++
+
+Receive SNMP TRAP/INFORM messages with the following options:
+
+* SNMPv3
+* with USM users:
+
+  * 'usr-md5-des', auth: MD5, priv DES, ContextEngineId: 8000000001020304
+  * 'usr-md5-none', auth: MD5, priv NONE, ContextEngineId: 8000000001020304
+  * 'usr-sha-aes128', auth: SHA, priv AES, ContextEngineId: 8000000001020304
+
+* over IPv4/UDP, listening at 127.0.0.1:162
+* print received data on stdout
+
+Either of the following Net-SNMP commands will send notifications to this
+receiver:
+
+| $ snmptrap -v3 -u usr-md5-des -l authPriv -A authkey1 -X privkey1 -e 8000000001020304 127.0.0.1 123 1.3.6.1.6.3.1.1.5.1
+| $ snmptrap -v3 -u usr-md5-none -l authNoPriv -A authkey1 -e 8000000001020304 127.0.0.1 123 1.3.6.1.6.3.1.1.5.1
+| $ snmpinform -v3 -u usr-sha-aes128 -l authPriv -a SHA -A authkey1 -x AES -X privkey1 127.0.0.1 123 1.3.6.1.6.3.1.1.5.1
