+Sending notification with OBJECT's
+++++++++++++++++++++++++++++++++++
+
+Send SNMP TRAP notification using the following options:
+
+* SNMPv2c
+* with community name 'public'
+* over IPv4/UDP
+* send TRAP notification
+* to a Manager at 127.0.0.1:162
+* with TRAP ID IF-MIB::ifLink as MIB symbol
+
+The IF-MIB::ifLink NOTIFICATION-TYPE implies including four other
+var-binds into the notification message describing the incident
+occurred. These var-binds are:
+IF-MIB::ifIndex."x"
+IF-MIB::ifAdminStatus."x"
+IF-MIB::ifOperStatus."x"
+IF-MIB::ifDescr."x"
+
+Where "x" is MIB table index (instance index).
+
+Functionally similar to:
+
+| $ snmptrap -v2c -c public 127.0.0.1 0 1.3.6.1.6.3.1.1.5.3 IF-MIB::ifIndex."1" IF-MIB::ifAdminStatus."1" IF-MIB::ifOperStatus."1" IF-MIB::ifDescr."1"
