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 
Note:

For SBC SWe deployments, the preceding three default profiles are assigned automatically to MC1, MC2, and MC3 when a standard or custom traffic profile is activated. For SWe deployments in which the default traffic profile is activated, a separate set of overload profiles is provided and mapped to MC1, MC2, and MC3 automatically:

  • sweOverloadProfileMC1
  • sweOverloadProfileMC2
  • sweOverloadProfileMC3

    Modified: for 6.2.1

 

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.

To View Overload Profiles

On the SBC main screen, go to Configuration > Profile Management > Category: System Profiles >  Overload Profile.

The Overload Profile window is displayed.

Profile Management - System Profiles - Overload Profile

 

To Enable or Disable Overload Profiles

To enable or disable any of the Overload Profiles in the list, click the radio button next to the specific Overload Profile name.

Edit Selected Overload Profile Parameters

Parameter Description
Name

Overload Profile name. The name cannot be changed.

State

Administrative state of the Overload Profile.

  • Disabled (default) – Set to "Disabled" to change parameter values. While disabled, congestion processing continues to use the previous profile values.
  • Enabled – Set to "Enabled" to allow this profile to be referenced by a system congestion level whereby all parameter values are validated.

Make the required change and click Save at the right hand bottom of the panel.

After you disable the Overload Profile object, use the windows positioned below the Overload Profile window to set the specific values for set/clear thresholds and set/clear duration for the profile. See the following pages for more information:
