The tmnxSubInfoEgrAggRateLimitLowReq notification is sent when the value of the object tmnxSubInfoEgrAggRateLimitLow changes. More information about the request is provided with tmnxSubAdditionalInfo. The text below explains a transition from false to true. [CAUSE] The system has received a request to reduce the egress aggregate rate below the minimum reserved bandwidth (and it has set the egress aggregate rate to the minimum reserved bandwidth). Such a request may come from Radius or IGMP, for example. [EFFECT] The subscriber can use less than the bandwidth requested (for multicast traffic, typically), but maintains the minimum reserved bandwidth (for high priority unicast traffic, typically). [RECOVERY] The recovery action, if any is needed, depends on the root cause.
