SNMP
The SNMP screen allows the user to configure the N-TAH’s SNMP function. This
function allows the N-TAH to automatically share information regarding the state of
alarm inputs, aux contacts, and monitored environmental conditions with the user’s
SNMP management software over the network.
The entire SNMP function can be enabled or disabled by selecting either of the Enable
or Disable radio buttons. This causes the entire SNMP function to be enabled or
disabled.
The names of the Get and Set communities can be changed from their default settings
to any text string of up to 39 characters. The Get community is used when retrieving the
current values from the N-TAH. The Set community is used when changing values on
the N-TAH, for example turning an aux contact on or off or changing an environmental
measurement warning or alarm value. The names of the communities must mach the
community names set in the user’s management software. This enables a degree of
security for controlling contacts or changing warning levels. The Set function can also
be independently disabled, so that it will only be possible to read data from the N-TAH.
Up to four SNMP servers can be programmed into the N-TAH. When an alarm input or
aux contact output changes state, or when an environmental probe reading goes in or
out of alarm or warning state, the N-TAH will send SNMP trap messages to every
configured SNMP server on the list. This function can be independently enabled or
disabled for every alarm, aux, or environmental reading.
