Prime Network Vision Status Indicators
Severity
Severity indicates the operational health of the element. An element has only one severity value at any
given time, and this value is displayed using a severity color. For more information about the colors used
to display the severity (or propagated severity) of network elements and links, see Alarm Indicators,
page 2-12.
Propagation
Severity is propagated upward in the network hierarchy, displaying th e top-most se ver ity of the netw ork
element’s children and thereby ensuring that every single problem in the network is propagated and
visible.
The same severity propagation rules that are used for network elements apply to links. A link is a child
object of an aggregation only if it is fully contained in the aggregation; that is, the network elements on
both sides of the link are part of the aggregation, as shown in Figure 2-7 and Figure 2-8.
Figure 2-7 Link Severity Example 1
Figure 2-7 shows critical link 1 between two network elements in an aggregation. This critical link
affects the severity of aggregation 2. That is, the aggregation is critical because it contains a link with a
critical severity. Link severity affects the context.
Figure 2-8 Link Severity Example 2
Figure 2-8 shows critical link 1 that forms part of a link aggregation. This affects the severity of link 2
because it contains a link with a critical severity.
New Ticket Propagation
A new ticket indicates a new local fault or accumulates and propagates the number of new faults in its
children.
