> Traffic Performance Optimizer Thresholds
> Thresholds generate alerts or alarms based on either the total number of Traffic Performance Optimizer (TPO) calls setup by the system during the specified polling interval, or on the number of currently active calls only.
> Alerts or alarms are triggered for call setups based on the following rules:

> • | Enter condition: Actual number of call setups > or = High Threshold

> • | Clear condition: Actual number of call setups < Low Threshold.

> If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval. The default value is 0, which means there will be no monitoring.
> The polling interval is in seconds and it is an integer between 30 and 60000. Entries will be rounded up to the nearest 30 seconds. The default interval value is 900 seconds.
> Configuring TPO Thresholds
> This section describes how to enable and configure TPO thresholds.
> Enabling TPO Thresholds
> To enable TPO thresholds use the following configuration:
> configure
> threshold monitoring tpo
> end
> Configuring Threshold Poll Interval
> To configure threshold poll interval use the following configuration:
> configure
> threshold poll tpo-dns-failure interval <interval>
> threshold poll tpo-low-compression-gain interval <interval>
> threshold poll tpo-rto-timeout interval <interval>
> end
> Configuring Thresholds Limits
> To configure threshold limits use the following configuration:
> configure
> threshold tpo-dns-failure <high_thresh> clear <low_thresh>
> threshold tpo-low-compression-gain <high_thresh> clear <low_thresh>
> threshold tpo-rto-timeout <high_thresh> clear <low_thresh>
> end
> Saving Your Configuration
> When you configure thresholds they are not permanent unless you save the changes. When you have completed configuring thresholds, save your configuration as described in the Verifying and Saving Your Configuration chapter.
