cable event throttle-interval
cable event throttle-interval
To specify the throttle interval, which controls how often the Cisco CMTS generates SNMP traps and
SYSLOG messages for DOCSIS event messages, use the
cable event throttle-interval command in
global configuration mode. To restore the default behavior, use the no form of this command.

Command Modes Global configuration
Command History
Usage Guidelines The DOCSIS 1.1 specifications require the CMTS to generate a set of messages for DOCSIS-specific
events. In certain situations, such as a power outage that causes a mass reregistration of cable modems,
this can generate such a large volume of event messages that it can impact system performance.
To avoid this possibility, use the cable event throttle-interval command, together with the cable event
throttle-threshold command, to specify the maximum number of SNMP traps or SYSLOG events that
the Cisco CMTS can generate for DOCSIS events over a specific interval:
•
cable event throttle-interval —Specifies the length of the throttle interval.
•
cable event throttle-threshold —Specifies the maximum number of SNMP traps and SYSLOG
events that the Cisco CMTS can generate during that period.
The threshold value counts DOCSIS events, not SNMP traps or SYSLOG messages. If a DOCSIS event
generates both an SNMP trap and a SYSLOG message, the Cisco CMTS counts it as only one event.
Note
The cable event throttle-interval and cable event throttle-threshold commands do not have any effect
unless the cable event throttle-adminStatus has been configured to allow the throttling of DOCSIS
event messages.
Tip
For more information about DOCSIS SYSLOG services and event messages, see Section 4.4.2.2.2,
SYSLOG Message Format, in the
DOCSIS 1.1 Operations Support System Interface (OSSI)
Specification (SP-OSSIv1.1-I06-020830). For more information about all cable-related event messages
that can be generated on the Cisco CMTS router, see the Cisco CMTS Error Message manual.
