+Multiple concurrent notifications
++++++++++++++++++++++++++++++++++
+
+Send multiple SNMP notifications at once using the following options:
+
+* SNMPv2c and SNMPv3
+* with community name 'public' or USM username usr-md5-des
+* over IPv4/UDP
+* send INFORM notification
+* to multiple Managers
+* with TRAP ID 'coldStart' specified as a MIB symbol
+* include managed object information specified as var-bind objects pair
+
+Here we tag each SNMP-COMMUNITY-MIB::snmpCommunityTable row
+with the same tag as SNMP-TARGET-MIB::snmpTargetAddrTable row
+what leads to excessive tables information.
+
+Functionally similar to:
+
+| $ snmpinform -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2
+|
+| $ snmpinform -v3 -l authNoPriv -u usr-md5-none -A authkey1 \
+|              demo.snmplabs.com \
+|              12345 \
+|              1.3.6.1.6.3.1.1.5.2
