Event Messages
The C4/c CMTS generates asynchronous event messages, or events, in two ways:
As part of normal operations.
In response to error conditions.
Asynchronous Notification Management
The C4/c CMTS uses Asynchronous Notification Management (ANM) to log event messages. Logging occurs when any
unsolicited event is generated.
Event Management Subsystems
Network management personnel can define and route event messages to several event management subsystems. These
subsystems include:
The logging history buffer
The system console
Telnet and SSH sessions
The local log: volatile and non-volatile (also found in the docsDevEventTable MIB table)
A Syslog server (up to eight Syslog servers are supported)
One or more SNMP management stations
Other logging functionality can be managed through the DOCS-CABLE-DEVICE-MIB.1
The figure below shows how events are routed to one or more of the event management subsystems within the C4/c
