eMonitor/Alarm Notification
Strata CIX
Strata CIX
* If the CIX is behind a NAT router eMonitor will be able to monitor (receive) CIX alarms but,
will not be able to send alarm programming to the CIX unless the NAT router performs Port
forwarding to the CIX IP address.
Alarm Notification is sent on a card slot basis, not per port. This helps reduce network loading. Use
the Port Make Busy program to determine individual port status (Utilities/Maintenance/Cabinet).
Expansion Cabinet power supply alarms are reported as System Resource (Slot 0x00, x = cabinet
number) alarms. SMDR Memory Buffer Full, CTI Link Down, SMDR Link Down and SMDI Link
Down are reported as System Resource (Slot 0100) in Cabinet 1.
When an alarm condition occurs the CIX processor records the error code in the alarm buffer. The
processor will send a command to light Alarm Indicators on stations and send the SNMP Trap data
to as many as 11 IP addresses. The trap data can be read by eMonitor or another alarm monitor
software application.
The Alarm Notification SNMP Trap Data messages are sent from the CIX processor to eMonitor
using UDP port 162. To allow eMonitor to send SNMP messages to the CIX processor, port 161 on
the NAT router must be port forwarded to the CIX IP address. Any firewall between the CIX and
the external console will need this port enabled.
When the CIX detects an alarm condition, the Alarm buffer sends the notification. When the alarm
condition has been cleared for several seconds the CIX will send an alarm clear message to
eMonitor, and turn off the alarm notification LED on stations.

On T1 and PRI alarms only, if the Clear Alarm Buffer Command is invoked (Utilities/
Operations/System Alarm), the system will not issue another alarm notification even if the
T1 or PRI alarm condition persists. Only a new T1 or PRI alarm condition will cause
another alarm notification.
