SNMP - Simple Network Management Protocol

SNMP is a management tool used to monitor and control remote network devices.
It can be used to poll specific information from the agent.

SNMP must be installed on a Windows NT computer to enable Performance Monitor
to monitor TCP/IP activity to and from your computer.

An SNMP community is a functional group of SNMP agents and managers.
Agents receive requests and report information to the SNMP managers for
the communities the agent belongs to.

An SNMP trap is an alert that, under predefined conditions or thresholds,
the SNMP agent sends to the SNMP manager.


- Send Authentication Trap - sends a message to the trap destinations if it receives
  a request with an incorrect community name.

- Only Accept SNMP packets from these hosts - allows agent to accept only packets
   from defined hosts. Defined hosts are known by either their IP or IP.
