configuration fails within one hour after it starts running as the active FP. See
also

state

An operational value indicating the high-level condition of a component. Its
range of values is usually small. For example, the usage state can be idle,
active, or busy, while the amount-used status could vary from 0 percent to 100
percent. State changes can generate alarms or service change notifications.
Status changes can generate alarms when certain thresholds are passed.

state change notification (SCN)

In OSI, a notification of a change of OSI state and status values. In Nortel
Multiservice Switch systems, the notification is generated only by a change in
operational state changes in a preselected set of components. Nortel
Multiservice Data Manager uses SCNs to update the state of components that
are being displayed.

state walk

infrastructure to obtain or synchronize fault information from a device (for
example, a Nortel Multiservice Switch node).

static_local
