• Congestion Condition Thresholds: Thresholds dictate the conditions for which congestion control is enabled and establishes limits for defining the state of the system (congested or clear). These thresholds function in a way similar to operation thresholds that are configured for the system as described in the Thresholding Configuration Guide. The primary difference is that when congestion thresholds are reached, a service congestion policy and an SNMP trap, starCongestion, are generated.
• Port Utilization Thresholds: If you set a port utilization threshold, when the average utilization of all ports in the system reaches the specified threshold, congestion control is enabled.
• Port-specific Thresholds: If you set port-specific thresholds, when any individual port-specific threshold is reached, congestion control is enabled system-wide.
• Service Congestion Policies: Congestion policies are configurable for each service. These policies dictate how services respond when the system detects that a congestion condition threshold has been crossed.Important: This section provides the minimum instruction set for configuring congestion control. Commands that configure additional interface or port properties are provided in the Subscriber Configuration Mode chapters of the Command Line Interface Reference.

• There are several additional threshold parameters. See the “Global Configuration Mode” chapter of the Command Line Interface Reference for more information.congestion-control policy <service> action { drop | none | redirect | reject }
• For the MME redirect is not available.context <context_name>
• Optional: If the congestion control policy action was configured to redirect, then a redirect overload policy must be configured for the service(s) that are affected.
• There are several service configuration modes that you can configure. See the Command Line Interface Reference for a complete list of modes.
• You can set various options for redirection. See the Command Line Interface Reference for more information.context <context_name>subscriber name <subscriber_name>context <context_name>subscriber <subscriber_name>
• overload-disconnect is not supported for the CSCF service.
