Configuring the Overload Condition Profile
To configure this feature use the following configuration:
config
profile overload overload_profile_name
overload-exclude-profile self-protection self_protection_profile_name
node-level
tolerance
minimum min_percentage
maximum max_percentage
reduction-metric
minimum min_percentage
maximum max_percentage
interface gtpc
overloaded-action advertise
advertise
interval interval_value
change-factor change_factor_value
validity-period validity_period_value
end
NOTES:
-
profile overload overload_profile_name —Specify the overload profile name.
-
overload-exclude-profile self-protection self_protection_profile_name —(This is an optional configuration) Exclude messages from throttling decisions in self-protection condition.
-
tolerance minimum min_percentage maximum max_percentage —Specify the system overload limits. Refer the following scenarios:
-
When the system load is less than min_percentage , the system is in a normal state.
-
When the system load is in between min_percentage and max_percentage , the system is in an overloaded state. In this scenario, the node overload control action is triggered.
-
When the system load is greater than max_percentage , the system is in a self-protection state. In this scenario, the self-protection action is triggered.
-
max_percentage must be an integer in the range of 1-100. The default value is 95.
-
min_percentage must be an integer in the range of 1-100. The default value is 80.
-
-
reduction-metric minimum min_percentage maximum max_percentage —Specify the reduction metric limits. Refer the following scenarios:
-
Both percentage values, min_percentage and max_percentage work along with the tolerance configuration.
-
The percentage value max_percentage must be an integer in the range of 1-100. The default value is 100.
-
The percentage value min_percentage must be an integer in the range of 1-100. The default value is 10.
Example: Send 10 percent OCI to peer nodes, when the load is 80 percent, and 30 percent, when the load is 95 percent, during the following conditions:
-
tolerance min_percentage is 80 and max_percentage is 95.
-
reduction-metric min_percentage is 10 and max_percentage is 30.
-
-
interface gtpc overloaded-action advertise —Configures the action on GTPC interface when a node gets overloaded. GTPC includes S5/S8/S11/S2b interfaces. Certain actions apply only to specific interfaces.
-
advertise interval interval_value —Specify the periodicity of sending LCI to the peers in seconds. Must be an integer in the range of 0-3600. The default value is 300 seconds.
-
advertise change-factor change_factor_value —Specify the change-factor value. GTPC sends the LCI to corresponding peers, if the difference between the current load value and the lastly indicated load value is greater than the change-factor value. Must be an integer in the range of 1-20. The default value is five.
-
advertise validity-period validity_period_value — Specify the validity period of the advertised OCI value in seconds. Must be an integer in the range of 1-3600. The default value is 600 seconds.
