Threshold values

There are three performance monitoring threshold values:

•hard-coded default threshold values (facility type)

•default threshold values defined by the user (facility type)

•threshold values defined by the user (facility type)

Hard-coded default threshold values (facility type)

Each facility type has a set of hard-code default performance monitoring threshold values. You cannot edit these values. You can, however, define your own performance monitoring threshold values.

User defined default threshold values (facility type)

Each facility type has a set of default values that the user can define. The initial default values are derived from the hard-coded factory default threshold values. However, you can change these default values at any time.

User defined threshold values (facility)

You can set a facility slot or port to

•specific threshold values

•the default threshold values defined for that facility type

The threshold values for each specific facility are initially derived from the default threshold values for the matching facility types.

If you delete a facility with customized threshold values and add the facility again, the threshold values specific to the facility revert to the default threshold values. When you replace threshold values that you program, the programmed values stay with the network element.

If you replace a circuit pack other than the shelf processor, the threshold values are recovered from the shelf processor.

If you replace the shelf processor, the threshold values are recovered from other circuit packs in the network element.
