Chapter 2 Cisco CMTS Configuration Commands
cable event throttle-threshold
cable event throttle-threshold
To set the maximum number of SNMP traps and SYSLOG messages that the Cisco CMTS can generate
for DOCSIS event messages during the throttle interval, use the
cable event throttle-threshold
command in global configuration mode. To restore the default number, use the no form of this command.

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-threshold command, together with the cable event
throttle-interval 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.
number Maximum allowable number of DOCSIS events for which the
Cisco CMTS can generate SNMP traps and SYSLOG messages during
the throttle period. The valid range is 0 to 2147483647, with a default
of 10.
