Object States
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 1-8 EM Object States
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 page 3-40 or on page 5-44.) 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.
Normal State
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 whether their presence and to
current state. For instance, chassis presence polling occurs every minute while module and interface
presence polling occurs every five minutes.
