9.5.4 Sources of EMS Raised Alarms
In addition to reporting NE-generated alarms, the EMS monitors and reports alarms on the EMS itself;
for example, loss of connectivity to NE, and so forth.
The EMS monitors and reports the NE-specific alarms (see Table 9-9) and non-NE-specific alarms (see
Table 9-10).
See Appendix F, “Cisco MGM CORBA Gateway Events” for details of the Cisco MGM CORBA
Gateway events.
Note NE-specific alarms can be viewed and accessed by users who are assigned to the particular NE.
Description Displays a brief description of the alarm or event.

NE-Specific Alarms Description
Loss of communication to an NE When the system detects loss of connectivity to an NE, an EMS alarm is generated in the
Alarm Browser. This EMS alarm is cleared when the system reestablishes connectivity
to the NE or when the NE is marked Out of Service.
Automatic or manual memory
backup failure
If an automatic or manual memory backup job fails, an EMS alarm is generated in the
Alarm Browser. An individual EMS alarm is generated for each memory backup failure
that occurs. All instances of the backup-related EMS alarms are cleared (for that
particular NE) when the memory backup succeeds or when the NE is marked Out of
Service.
Switching IP addresses When an active IP address switches from the primary to the secondary IP address, an
alarm will be generated. It is only cleared when the address is switched back to the
primary IP address or when communication to the NE is lost.
Failed PM data retrieval An alarm will be generated for every PM data retrieval failure. PM 15-min Retrieval Fail
Alarms are generated if the system has not retrieved 15-min PM data after the number of
times to retrieve PM data has been reached. These alarms can be cleared manually or
cleared automatically if a Lost PM alarm is generated or if PM data is retrieved.
Lost PM data An alarm will be generated for all lost PM data. PM lost alarm 15-minute is generated
when:
• The EMS is not able to collect PM data for 15 minutes and the NE’s PM collection
is set to 15 Min.
• The EMS is not able to collect 15-minute PM data after 8 hours. If there are
outstanding PM 15-min Retrieval Fail Alarms, these alarms will be cleared and the
PM 15-min Lost PM Bucket Alarm is generated.
These alarms can be cleared manually. Lost PM data alarms are generated only if the PM
collection is set to 15-Min.
