Create Overload Profile
The overload profile determines the various conditions for overload control and throttling decisions.
To create the overload profile, use the following sample configuration:
config
profile overload overload_profile_name
overload-exclude-profile self-protection overload_exclude_profile_name
node-level
tolerance minimum min_percentage maximum max_percentage
reduction-metric minimum min_percentage maximum max_percentage
advertise [ interval oci_broadcast_interval | change-factor oci_change_factor | validity-period oci_validity_period ]
interface gtpc overloaded-action advertise
peer-level
message-prioritization group1 weight group2 weight
interface gtpc
action throttle
end
NOTES:
-
profile overload overload_profile_name : Specify the overload profile name. overload_profile_name must be an alphanumeric string.
ImportantYou can configure only one overload profile with this command. Create exclude profile before configuring overload profile.
-
overload-exclude-profile self-protection overload_exclude_profile_name : Specify the exclude profile name that is configured for use during overload self-protection mode.
overload_exclude_profile_name must be an alphanumeric string.
-
node-level : Specify to apply the configuration only for the overloaded SMF node.
-
tolerance minimum min_percentage maximum max_percentage : Specify the minimum and maximum percentage of the system load tolerance. min_percentage and max_percentage must be an integer in the range of 1-100.
min_percentage : This value is the tolerance level below which the system is considered to be in Normal state. Default value is 80.
max_percentage : This value is the tolerance level above which the system is considered to be in Self-protection state. Default value is 95.
If the value is between the configured minimum and maximum tolerance values, then the system is in Overloaded state.
-
reduction-metric minimum min_percentage maximum max_percentage : Specify the minimum and maximum percentage of the traffic reduction factor. min_percentage and max_percentage must be an integer in the range of 1-100.
min_percentage : This value is the percentage of traffic reduction in tandem with minimum tolerance configuration. Default value is 10.
max_percentage : This value is the percentage of traffic reduction in tandem with maximum tolerance configuration . Default value is 100.
-
advertise interval oci_broadcast_interval : Specify the periodic interval for sending OCI to the GTP-C peers.
oci_broadcast_interval must be an integer in the range of 0-3600. Value 0 indicates that the OCI is sent in all the messages. Default value is 300 seconds.
-
advertise change-factor lci_change_factor : Specify the minimum change between current OCI and last indicated OCI, after which the OCI advertising occurs.
oci_change_factor must be an integer in the range of 1-20. Default value is 5.
-
advertise validity-period oci_validity_period : Specify the validity period of the advertised OCI value.
oci_validity_period must be an integer in the range of 1-3600. Default value is 600 seconds.
-
interface gtpc overloaded-action advertise : Specify to enable OCI publish or broadcast on GTP-C interface when the node is overloaded. By default, this option is disabled.
-
peer-level : Specify to apply the configuration only for the overloaded peer.
-
message-prioritization group1 weight group2 weight : Specify the ratio in which the messages need to be throttled for both the message groups. Each group contains a predefined set of messages from every SMF interface.
weight must be an integer in the range of 1-100. The default value is 50.
-
interface gtpc action throttle : Enables the throttling action over S6, S8, and S2b interfaces.
