Viewing Link Impact Analysis
• T1
• VRF
IP addresses are displayed in IPv4 or IPv6 format, as appropriate.
Depending on the type of link, the following areas might be displayed:
• Affected Parties—Enables you to view all elements potentially affected by the link. For more
information, see Viewing Link Impact Analysis, page 6-12.
• Labels—Enables you to view all LSPs on an Ethernet link. For more information, see Viewing LSPs
Configured on an Ethernet Link, page 18-11.
• VCs—Enables you to view configured and misconfigured VCs on an ATM link. For more
information, see Viewing ATM VPI and VCI Properties, page 20-10.
Ticket and Events Pane
The ticket and events pane is displayed at the bottom of the link properties window and contains the
following tabs:
• Tickets—Displays the tickets that are collected on the selected element, service, or component in
the navigation pane.
Table 9-3 describes the information that is available in the Tickets tab.
• Network Events—Displays all active network events associated with tickets and alarms, and all
archived events with a timestamp that falls within the specified events history size (see Adjusting
the Prime Network Vision GUI Client Settings, page 2-40).
Table 3-7 on page 3-15 describes the information that is available in the Network Events tab.
When displaying network events, Prime Network Vision monitors the history size value defined in the
Events tab of the Options dialog box (Tools > Options > Events). The default value is six hours and can
be changed in Prime Network Administration. In addition, Prime Network Vision limits the maximum
number of network and provisioning events that are sent from the server to client to 15,000 each. If the
number of network or provisioning events exceeds the limit specified in the Options Events tab or the
15,000 maximum limit, Prime Network Vision purges the oldest events from table. The purging
mechanism runs once per minute.
Tip You can display or hide the ticket and events pane by clicking the arrows displayed below the device
view panel.
Viewing Link Impact Analysis
Prime Network Vision enables you to select a network link and calculate the elements that might be
affected if the link were to go down. This enables you to perform proactive impact analysis when a fault
has not actually occurred.
Note Impact analysis applies only to physical links.
