Subsystem Processes That Send Event Messages

Not all event messages received by a management application come from SNAX/XF

and SNAX/APN. SNAX/XF and SNAX/APN generate event messages for events that

involve the objects under their control. The Subsystem Control Point (SCP) reports

events when SPI messages fail or upon an internal failure of SPI. The event messages

issued by SCP are described in the SPI Common Extensions Manual.

Event messages issued by SCP contain the subsystem ID of SCP; those issued by the

SNAX/XF and SNAX/APN contain the subsystem ID that is common to both. This

subsystem ID is described in Section 2, Standard Definitions

. The subsystem ID of SCP

is described in the SPI Common Extensions Manual. For general information about

subsystem IDs, refer to the SPI Programming Manual.

Event messages issued by the SNAX/XF and SNAX/XF subsystems are generated by

the service-manager process. The actual source of each event within SNAX/XF is

documented in the individual event-message descriptions.

Event Messages Sent by SNAX/XF

The SNAX/XF event messages are divided into seven categories:

•

Common Level 2 event messages

•

Line-handler event messages

•

PU event messages

•

LU event messages

•

Service-manager event messages

•

SPI event messages

•

Checkpointing event messages

The service-manager event messages are further divided into four subcategories:

•

General event messages

•

LU Network Services (LUNS) event messages

•

Communications Network Management (CNM) event messages

•

Configuration services (CS) event messages
