SNMP Traps in RedMAX Version 2.1
In RedMAX sector controllers with version 2.1 software, two SNMP traps are provided for
both local and GPS synchronization. When the AN100U/UX does not detect the clock input
signal (from either the Master or Master with GPS), a trap is sent. When the signal is
detected again, the trap state is cleared.
Similarly, when the AN100U/UX internal clock is out of phase with the Master or Master
with GPS clock, a trap is sent. When the internal clock is locked and tracking again, this
trap is cleared.
When either of these states are resolved, the trap is cleared, however another trap is not
sent to advice trap receivers such as RMS, that the internal clock is locked and tracking
again.You can only determine this by inspecting the GPS clock.
Refer to the RedMAX GPS Clock User Manual for information on clearing holdover mode
and re-arming the alarm indicator.
Refer to the Redline Management Suite User Guide for information on configuring and
using these SNMP traps as alarm indicators.
Managing SNMP Traps
Through your trap receiver (i.e. RMS) you can configure SNMP traps to provide notification
when any of the above traps have been received.
You must first configure an access control list (ACL) that includes all SNMP managers, to
which traps will be sent. Any SNMP get/set requests received from managers that are not
on the ACL, will be dropped. Refer to the RedMAX AN100U/UX Base Station User Guide
for details of creating and maintaining the SNMP access control lists.
You then need to configure the actual trap destinations. SNMP traps generated by the
sector controller will be sent to each of the defined trap destinations. You must then
configure your trap receiver to provide notification upon receipt of the trap. Refer to the
RedMAX AN100U/UX Base Station User Guide for details of maintaining the SNMP trap
destinations.

AN100U/UX Local Synchronization Trap
Trap Name and Setting
Description
RedMAXSynchronization
Trap
synchLost =set
The sector controller has detected a signal on the Sync OUT port, but
it is out of phase and synchronization is not currently possible. This will
result in an event log and status page message showing "No synchro".
A trap is sent to specified trap receivers such as RMS.
synchLost =cleared
When the AN100U/UX internal clock is locked and tracking again, this
trap is cleared.
RedMAXSynchronization
Trap
synchSignalLost=set
When a slave AN100U/UX does not detect the clock input signal from
the Master, a trap is sent to RMS. This trap can also be sent if the
Master with GPS can no longer detect the signal from the GPS.
synchSignalLost=cleared When the signal is detected again, the trap state is cleared.
