Description: This object represents the upper threshold of total amount of a particular traffic type that can be seen on a given interface, after which a storm event is declared and storm control action is taken.

The value represents the traffic as a percentage of total bandwidth of the interface, in units of 0.01 %.

For example, if a management station sets the value of cpscUpperThreshold.3.1 as 4000, it means the following: a) storm control is enabled on the interface with ifIndex = 3 for broadcast (1) packets b) if the broadcast traffic received per second on the interface is more than (4000*0.01 = 40%) of the total interface bandwidth, then the system will take storm control actions, as indicated by cpscAction.3 .

It should be noted that setting the upper threshold value to anything other than 100% results in storm control being automatically enabled on the given interface, for the given traffic type.

An implementation may not be able to support different threshold values for different traffic types, in which case changing the value for one traffic type will automatically result in the threshold value for other types also modified.

The default value of this object is implementation- dependent.
