Object States

Object states reflect the life cycle of an object. Whatever stage the object is in at any given time displays

in the state type. The state of an object can change frequently, depending upon what actions take place

on the object. All objects within the EM are in a specific state which appears at the bottom left corner

of each FCAPS window. The following figure highlights an object’s state.

Figure 1-10 EM Obj ect St ates

The two most common object states are Normal and Decommissioned. For example, when you deploy a

module in the EM, the initial state of the module is decommissioned. You can then commission the

module to begin active management. (For instruction on how to commission a module, see the

“Commissioning Modules” section on page3-35 or on page 5- 2 8 .) When you commission the module,

it passes through two transitory states: discovery, then commissioning. The commissioning process

determines which state to move the object into (typically Normal). This example reflects the basic

process of deploying and commissioning an object.

Certain states ripple down to objects below. For example, if you decommission a chassis, all subchassis

objects also decommission. If you enable performance logging on a module, all interfaces under the

module also enable.

By default, FCAPS windows refresh at a rate dependent upon the type of window. For example,

inventory windows refresh at a lower rate than performance windows. The average refresh rate is every

30 seconds.

The following sections describe the possible states that an object may be in and provides a description

of these states.

The normal state indicates that an object is operational. When an object enters the normal state, the EM

performs heartbeat polling on objects at varying intervals to determine their presence and current state.

For instance, chassis presence polling occurs every minute while module and interface presence polling

occurs every five minutes.
