The number of forwarding flow tables on the device reaches or exceeds 90% or 100% of the maximum number, an alarm is generated.

If the number of forwarding flow tables changes too rapidly within a short period of time, multiple alarms may be generated. As a result, the system records these alarms, affecting normal services on the device. To prevent the device from recording a large number of alarms, the system suppresses the alarms by setting the interval at which alarms are sent to longer than 30 minutes. That is, the system records an alarm at least 30 minutes after the last alarm was cleared.
