DOCSIS SAMIS Service Definitions
SAMIS for DOCSIS 3.0 service definitions are well structured and has two versions
—
SAMIS-TYPE-1 and
SAMIS-TYPE-2 and provide a different level of information details than SAMIS.
DOCSIS 2.0 SAMIS supports only event session (default type) and DOCSIS 3.0 SAMIS TYPE 1 and DOCSIS
3.0 SAMIS TYPE 2 support only interval and ad-hoc sessions.
SAMIS is collected based on configurable time intervals. Each interval is a different document and the Exporter
stops and starts a new session for a new interval. The interval starts from the last metering that has either
succeeded or failed, unlike the time-interval session that has a fixed starting point and an interval.
The SAMIS schema can be configured with the
cable metering ipdr session
command SAMIS-TYPE-1
and SAMIS-TYPE-2 schemas can be configured through the
cable metering ipdr-d3
command. These
schemas are mutually exclusive of each other.
Note
Limitation To DOCSIS SAMIS
•
Only a schema that is consistent with the
cable metering ipdr| ipdr-d3
command will work. If none
of the schemas are consistent, none of them will work.
•
Changing the SAMIS IPDR type will abort exporting IPDR data.
DOCSIS Diagnostic Log Service Definitions
This service definition defines the IPDR Streaming using a two-step process:
•
SNMP or other configuration management interface, such as the CLI is used to configure the Diagnostic
Log.
•
IPDR/SP is used to stream the Diagnostic Log instances.
These Diagnostic Log service definition schemas support the following collection methods:
•
The Cisco CMTS supports streaming of the DIAG-LOG-TYPE record collections as an ad-hoc session.
•
The Cisco CMTS supports streaming of DIAG-LOG-EVENT-TYPE record collections as an event
session. For event-based Diagnostic Log records, the Cisco CMTS streams the record when the event
is logged in the Diagnostic Log and an IPDR message is transmitted to the Collector.
•
The DOCSIS-DIAG-LOG-DETAIL-TYPE supports the following collection methods:
◦
Time interval
—
Follows a schedule based on session configuration to export data on a periodic
time interval. When a given time interval end is reached, the Exporter collects the diagnostic log,
then streams the record to the Collector associated with this session. For time interval based
Diagnostic Log records, the Cisco CMTS streams a snapshot of the Diagnostic Log at the scheduled
collection time.
◦
Ad-hoc
—
When the Exporter receives a "FlowStart" message, it triggers the application to collect
the diagnostic record and send the data to the Collector.
