Multiple concurrent notifications
+++++++++++++++++++++++++++++++++
Send multiple SNMP notifications at once using the following options:
* SNMPv2c and SNMPv3
* with community name 'public'
* 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:
| $ snmptrap -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2
| $ snmpinform -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2
| $ snmptrap -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2
