10. SNMP Traps
SNMP is an acronym for "Simple Network Management Protocol". The
SNMP Trap function allows Buffer Mode Ports to send a message to two
different SNMP Managers, indicating the amount of data currently stored in
• The SNMP Trap function is only available to Buffer Mode Ports.
• This option is not available to RS232 Port 1, which is reserved as
a "System SetUp Port", and therefore, cannot be conﬁgured as a
Buffer Mode Port.
• The SNMP feature cannot be conﬁgured via the SNMP Manager.
• SNMP reading ability is limited to the System Group.
• The SNMP feature includes the ability to be polled by an SNMP
• When the /R command is invoked, the counter for the SNMP Trap
function will automatically be reset.
The SNMP Trap function is individually conﬁgurable for RS232 Ports 2
through 16. If you wish to employ this feature it must be enabled at each
desired port. To conﬁgure the SNMP Trap function, proceed as follows:
1. Access command mode using an account and port that permit Supervisor
2. Port Parameters Menu: Access the Port Parameters Menu for the
desired port as described in Section 5.7.2, and then set the following
a) Port Mode: Set the Port Mode to "Buffer".
b) SNMP Trap Level: Enable the SNMP Trap function and select the
byte level. The byte level determines the number of bytes the buffer
must contain in order to cause an SNMP trap to be sent. Note that
when the byte level is set to "0" (zero), the SNMP Trap function is
