A network path view displays every device and link encountered
between the start and end devices. Issues affecting devices and links
on that path are displayed graphically. You can edit the path view
manually by excluding devices from the view. You can retrace a path,
or edit it before retracing it. You can also copy a path view to another
view container, or delete it.
Before you begin
Before you can work with network paths, the administrator
must have successfully completed the first network discovery, and
network views must be configured for your user ID.
About this task
You can only edit or retrace IP paths. MPLS TE paths are populated during discovery and
cannot be edited or retraced. Note: MPLS TE paths are displayed by default under the itnmadmin
views. This can be altered by editing the
$NMGUI_HOME/profile/etc/tnm/topoviz.properties
file
and changing the values for the following view attributes:
- topoviz.pathview.accesslevel
- topoviz.pathview.accessid
Procedure
-
Click the Incident icon and select .
The Path Views window opens. Any network paths that have been created are shown.
- To interact with network paths, use the following buttons:
- Views drop-down
- Use to find and display a specific path view. Path views are arranged
in a tree structure based on path view container types, for example, 'AUTO', 'IP
Paths', 'itnmadmin', or 'Client Views'.
- Each path view displays the view name, the number of hops in the
path, and the highest severity alert (if any) associated with that
path view.
Note: You can click the severity icon to launch the Active
Event List with that event selected. You can also select a device,
and then click Find In Network View or Find
In Hop View from the context menu.
- New path
- Opens the Trace Network
Path window,
where you can create a new path view.
Note: IP path views only.
Note: You can only trace a path across a single domain. All devices
specified in the Trace Network
Path window must be in the same
domain.
- Depending on the user roles set by your administrator for your
user ID, you may be able to save the new path to your list of path
views.
- Edit path
- Click here to edit a path view that is currently being displayed.
The Trace Network
Path window
opens populated with the details for the path, any of which can be
changed. You trace and display the edited path by clicking Save
and Trace.
Note: IP path views only.
Note: You can only trace a path across a single domain. All devices
specified in the Trace Network
Path window must be in the same
domain.
- Retrace path
- Click here to retrace the path between the devices in the currently
selected path view. Paths between devices in a network are dynamic,
and therefore trace results may be different each time a path is retraced.
Note: IP
path views only.
- Copy or move path
- Opens the Copy or Move Path dialog. Use to
copy or move a selected path to a different view container.
- Delete path
- Click here to delete the path view that is currently being displayed.
If the path view is the last view in a container, the container will
be deleted as well.
Note: The path stored in the NCIM database is
not deleted. If any user recreates the deleted path with the same
settings, a new trace occurs and the existing path in the NCIM database
is updated with the new trace results.
- Toggle search
- Displays a search box below the toolbar from which you can search for a view.
- Save
- Saves the view or view container. This button appears only when a view is displayed.
- Save as Image
- Saves the view or views as an image. Displayed only for users with the
ncp_printing_allowed
role.
- Print
- Prints the view or view container. Displayed only for users with the
ncp_printing_allowed
role.
- Find in Map
- Searches for a device in the topology map.
- Select
- Changes the cursor to select mode, which is the default. When the cursor is in select mode, if
you click a device in the topology display panel, that device is selected. You can reposition nodes
by dragging them using this mode. You can save the position of nodes by using the
Save button. The positions of nodes that are not connected to other nodes are
not saved, unless this network view or all network views are configured to maintain the position of
nodes after rediscovery.
- Pan
- Changes the cursor to pan mode. When the cursor is in pan mode, the cursor changes to the
following icon: . Click and hold the left mouse button to grab the topology; you can then use the mouse to
move the topology.
- Select Zoom
- Changes the cursor to select-zoom mode. When the cursor is in select-zoom mode, you can use the
mouse to draw a rectangle over a particular area of the topology. When you release the mouse button,
the screen zooms in to the rectangle you have drawn.
- Interactive Zoom
- Changes the cursor to interactive-zoom mode. When the cursor is in interactive zoom mode, hold
down the mouse button and move the cursor up to zoom out, and while hold down the mouse button and
move the cursor down to zoom in.
- Toggle Overview
- Displays a thumbnail of the whole view in the bottom right corner, with a box around the region that is currently visible.
- Zoom In
- Zooms in to the view.
- Zoom Out
- Zooms out of the view.
- Fit in Window
- Fits the current view to the size of the Topology Display window.
- Hierarchical Layout
- Changes the format of the view to a hierarchical layout. This option
is not available for views that cannot contain connectivity information, such as Unassigned network
views.
- Symmetric Layout
- Changes the format of the view to a symmetric layout. This option
is not available for views that cannot contain connectivity information, such as Unassigned network
views.
- Orthogonal Layout
- Changes the format of the view to an orthogonal layout. This option
is not available for views that cannot contain connectivity information, such as Unassigned network
views.
- Circular Layout
- Changes the format of the view to a circular layout. This option
is not available for views that cannot contain connectivity information, such as Unassigned network
views.
If you chose to create a new path or retrace an existing path, then
Path
View window displays the devices resulting from your search.
What to do next
If the path was not successfully traced, then you get a path trace error, indicating the reason that the path could not be traced. To see more detailed path trace output, click the error at the top of the Trace Network
Path window. Detailed path trace output opens in a second window. To troubleshoot the path trace, refer to the related information on troubleshooting path views.
