# 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.

Syntax

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 to flash memory, an external memory device, and/or a network location using the Exec mode command save configuration. For additional information on how to verify and save configuration files, refer to the System Administration Guide and the Command Line Interface Reference.
