SETTING UP ARC PLUS SL TO SEND TRAPS
To configure the ARC Plus to send SNMP Traps, select
SNMP Agent Settings…
from the
Edit > Settings
menu. The following dialog box will be displayed>
Edit>Settings>SNMP Agent Settings
The SNMP community string is used by an SNMP manager as a means to authenticate the SNMP agent. If a
unique string is specified here for the ARC Plus, it must also be pre-configured in the SNMP manager(s) that
will be receiving traps from the ARC Plus. The community string can be set to any desired text string.
ARC Plus SL can be configured to send traps to up to four different SNMP managers. The IP address and UDP
port for each manager must be entered in the fields shown above. The default port value of 162 is often
used for trap transmission.
No SNMP traps will be generated for an alarm condition on a muted channel. If a channel is set to mute
while an alarm condition is active, SNMP trap generation for that channel will stop. If a channel is taken out
of mute while an alarm condition is active, SNMP trap generation for that channel will begin.

This trap is sent when the underlying alarm condition returns to normal.
1.3.6.1.4.1.26079.2000.1.0.3

The trap OID or Object Identifier tells the SNMP manager which specific message type has been received.
Along with the OID, each of these trap messages includes a data value formatted as an Octet String variable,
containing an ASCII string. For the first 3 traps listed above, the associated ASCII string is made up of 4 parts:
