Ip Pool Utilization Thresholds - Cisco ASR 5000 Series Thresholding Configuration Manual

Chapter 12

IP Pool Utilization Thresholds

When IP address pools are configured on the system, they can be assigned to a group. All configured public IP address
pools that were not assigned to a group are treated as belonging to the same group (automatically named "Public IP
Pools"). Individually configured static or private pools are each treated as their own group.
IP address pool thresholds can be configured for all IP pools or pool groups configured within a system context or for
individual pools or groups. These thresholds generate alerts or alarms based on calculations pertaining to percent-
available for pool groups and percent-free, percent-on-hold, percent-released, and percent-used for individual pools.
Alerts or alarms are triggered for IP address pool utilization based on the following rules:
Enter condition: When the actual IP address utilization percentage passes, or is equal to, the configured
Threshold value an alert or alarm is set.
Clear condition: When the actual IP address utilization percentage passes the Threshold value the alert or alarm
is cleared.
If a trigger condition occurs within the polling interval, the alert or alarm is not generated until the end of the polling
interval.
The following table describes the possible methods for configuring IP pool utilization thresholds:
Method Description
Context- IP Pool Group: A single percent available threshold can be configured for all IP pool groups
level within a given context. The threshold is based on an aggregate measurement of available IP
addresses for all IP pools within each group. NOTE: Separate alerts or alarms are generated
for each group that experiences an event.
IP Pool: The following thresholds can be configured for all IP address pools configured within
a given system context:
Percent-free;
Percent-hold;
Percent-release;
Percent-used.
NOTE: Separate alerts or alarms are generated for each pool that experiences an event.
