11B.4 USING SNMP TRAPS
SNMP
traps are SNMP protocol messages initiated by the managed system to report a predefined error
condition. For the Octel Overture 200/300, these errors are hardware errors as logged in the Hardware
Error T
able. In addition to the name and ID of the logging system, all information for the hardware error
that caused the trap is listed.
Hardware errors have four priorities, ranging from priority 0 (lowest) to priority 3 (highest). An alarm
notification trap is made depending on the combination of the error priority and the number of times the
error (the same type with the same data) is logged. An alarm notification trap is made for the following
combinations of priority and number of times the error is logged:
Error
Priority
Number of T
imes
Error Logged
3 1
225
150
No
alarm notification is made for priority 0, which reports the test of the alarm (command
TE A).
Conditions for SNMP Trap Notification
The
CPU generates an SNMP trap request to the LAN card under the following conditions:
The SNMP manager system is configured, which means
System Parameter 235 — LAN: SNMP MANAGER IP ADDRESS, is configured.
or
Both System Parameter 233 — LAN: NAME SERVER IP ADDRESS, and System
Parameter 236 — LAN: SNMP MANAGER HOST ASCII NAME, are configured.
System Parameter 242 — LAN: SEND TRAP T
O THE SNMP MANAGER ON ALARM, is set to
YES.
A hardware error is logged a suf
ficient number of times for its priority to cause a system alarm
notification.
An alarm outcall is repeated until acknowledgment. There is no such acknowledgment from the
SNMP manager system for SNMP traps. SNMP notification is done only once per occurrence.
Configuring SNMP
The
following information must be configured through system parameters:
The SNMP manager
s IP address. System Parameter 235 — SNMP MANAGER IP ADDRESS
Sometimes SNMP managers may only have an ASCII name configured, and the actual mapping from the
ASCII name to an IP address is performed by a name server
. In this case, the following system
parameters must be configured:
