System Profiles - Overload Profile

An Overload Profile specifies a set of congestion thresholds and congestion durations you can assign to a particular machine congestion (MC) level. When the "set" threshold for the profile assigned to a particular congestion level is exceeded for the "set" duration, the congestion level is raised to a higher level and overload controls are applied to help alleviate the congestion. The profile also specifies "clear" congestion thresholds and durations. The clear values specify the level to which congestion conditions must fall for the specified duration in order to return to the previous congestion level. These minimum clear durations prevent repeatedly switching in and out of congestion levels. You may assign Overload Profiles to the system (that apply throughout the SBC).

The following default Overload Profiles are automatically assigned to define thresholds and duration to system congestion levels 1-3 (MC1, MC2, and MC3):

• defaultMC1
• defaultMC2
• defaultMC3 

In order to change its configuration, you must first disable an Overload Profile. Then, when you enable the profile, you cause all its parameter values to be validated. Once validated, these values are applied to the (system) congestion level to which you assign the profile. When you make a change in this manner, the system congestion level is cleared if the Overload Profile was being referenced. Standby modules also perform congestion processing but you cannot configure the module settings.
