== Configuring snmptrapd to allow traps in the door ==

By default, snmptrapd does not do anything with received notifications.  You have to tell it what you want to receive notifications.

=== Configuring snmptrapd to accept SNMPv1 or SNMPv2c notifications ===

To receive SNMPv1 or SNMPv2c notifications you need to tell snmptrapd your community strings.  The easiest way to do this is by using the ''authCommunity'' snmptrapd.conf configuration file token.  For example, this line:

  authCommunity log,execute,net public

Will let snmptrapd process notifications received using the "public" community string.  Those notifications may be logged, allowed to trigger executable actions (see below), and resend data to the network (forward).

=== Configuring snmptrap to accept SNMPv3 notifications ===

SNMPv3 adds security to the SNMP protocol and is a safer way to receive notification data.  But, it's a bit more complex to set up.  Configuration of SNMPv3 notifications is described fully on a [[TUT:Configuring snmptrapd to receive SNMPv3 notifications|separate page]]:
