Status fields, where available, are the accumulation of 'administrative' and

'operational' status’ of the component queried.

The three administrative statuses that can be assumed by a component are:

• Enabled: the component is enabled to operate in its normal mode, with all

normal parameters set. When the component is enabled, the component can

assume any of its operational statuses.

• Disabled: the component is disabled from operation. None of the component’s

operational statuses are valid in this state.

• Paused: the component is enabled and is running but is currently not accepting

additional service requests.

The two operational statuses that can be assumed by a component are:

• Up: the component is up and running normally

• Down: the component is down, due to some reason - normal or abnormal,

internal or external.

The Status column supports the combined list of these statuses:

• Up: This value is read-only. It indicates that the component is enabled and is

operating normally. For a component like a network interface, this means the

interface is enabled and connected to a valid link. For a service like DHCP, it

means that the service is enabled and is running normally.

• When the current status is 'Up', setting it to 'Enabled' or 'Continue' where

available, is a no-operation. Setting it to 'Disabled' disables the service, by

shutting it down and then disabling it. Where available, setting it to 'Paused'

pauses the service.

• Down: This value is read-only. This value indicates that the user has enabled the

component, and the component is unable to operate in an 'Up' state because of

normal or abnormal, internal or external errors. For example, if a network

interface is not in an 'Up' state because of no connection to an actual physical

link, it is a normal, external error. If a service like DHCP service is not in an 'Up'

state because of internal errors, it is an abnormal, internal error.

• When the current status is 'Down' setting it to 'Enabled' attempts to bring it to

'Up' state again. As a result it may stay at a 'Down' state. Setting it to 'Disabled'

disables the service. Where available, setting it to a 'Paused' or continued state

fail as the service is not yet running.

• Enabled: This value is write-only. This value never appears when read. For a

service that is enabled, one of its operational statuses (that is, Up or Down)

appears when its Status field is read.
