Use a filtered view to view parts of the network based
on topology database filters; for example, a network view showing
all Cisco devices on a given subnet.
Before you begin
If you want to store the view in a custom container, you must create the
container before you begin this task.
Procedure
-
Click the
Incident icon and select .
-
Click the Libraries tabe and click New
View
.
- Complete the General tab as follows:
- Name
- Type a name for the network view, dynamic view, or network view
container.
Important: It is best practice to use network view
names containing Latin characters only. Network views names containing non-Latin characters (for
example Cyrillic characters) are not supported as they cannot be imported and exported when
migrating to a new version of Network Manager.
- Parent
- Select the node under which the view appears in the hierarchy in the Navigation
Tree. To display the view on the top level, select NONE.
- Type
- Select Filtered.
- Layout
- Select Orthogonal, Circular,
Symmetric, Hierarchical, or Tabular layout.
- Map Icon
- If you want a different icon than the default icon to represent the view, click
Browse
to browse for an icon.
- Tree Icon
- If you want a different icon than the default icon to represent the view, click
Browse
to browse for an icon.
- Background Image
- Click Browse
to browse for an image to use as the
background for the view.
- Background Style
- Specify whether the background image is to be centered or tiled.
- Line Status
- Specify how the lines that represent the links between devices should be rendered.
- You can choose not to display any status, or to display the system default. Alternatively, lines
can be colored based on the associated Event Viewer event with the highest
severity, and can appear with an additional severity icon.
-
Set up the filter.
You have the following options:
- Click the Filter tab, and select a domain. Select the attribute table
that you want to use in the filter and type an SQL WHERE clause in the Filter
field.
- Click the Filter tab and click Edit
to use the Filter Builder GUI. The
Filter Builder has basic and advanced modes:
- In basic mode, select a field, comparator, and value from the lists. Use the radio buttons to
create Boolean relationships that combine multiple filters. To add more filters, click
Add new row
.
- In advanced mode, type the SQL WHERE clause into the field. Prefix each column name from the
table that you query with the table alias t.. For example,
t.entityName like 'rtr%'
The SQL syntax differs depending on which database you use to store topology. See the
documentation for your database type.
-
From the End nodes list, specify whether you want end nodes, such as
printers and workstations, to be displayed in the view.
- From the Connectivity list, select
the required connectivity:
- Layer 1
- Displays all physical connections.
- Layer 2
- Displays all switched connections between devices in the topology. A layer 2
view typically shows switch and hub connections.
- Layer 3
- Shows routers and the connections between routers. Switches are not normally
displayed.
Note: If switches have active connections involving layer 3 interfaces,
they are included in this layout.
The connections between devices are displayed as
follows:
- Connections between two layer 3 interfaces are shown as normal.
- Connections between a layer 3 and a layer 2 interface are shown as being between the layer 3
interface and the subnet to which the layer 2 interface belongs.
- Connections between two layer 2 interfaces are not shown.
- IP subnets
- Shows all devices within a subnet connected to a subnet cloud. This layout
helps to simplify the network map and also helps to make subnet membership clear. If you
want to see all connections, select one of the following options:
- Layer 1 for transmission layer connections.
- Layer 2 for data link connections.
- Layer 3 to show all routers and connections between them.
- OSPF
- Displays connections based on discovered OSPF information that includes router
roles, area membership, and connectivity.
- Probe
- Displays the probe topology, linking probe sources to probe targets.
- Converged Topology
- Displays the lowest layer links between devices based on all layer 1, 2
and 3 topology data available.
- PIM
- Displays connections based on PIM adjacency information.
- IPMRoute
- Displays connections based on IP Multicast upstream and downstream routing
information.
- Microwave
- Shows microwave connections only.
- Logical RAN
- Shows logical RAN connectivity. RAN entities are usually connected by
L1 or L2 connections, but this logical connectivity allows an overview of the main RAN entities to
be seen. Connections are usually implicit in the discovered data. For example, a base station
controller is connected at some level to the base stations it manages. Logical RAN connectivity
shows this relationship without any intermediate devices, such as multiplexers.
- No connections
- Does not present any of the discovered connections for the nodes
shown in the view.
- LTE Control Plane
- Displays a topology view of the LTE control plane.
- LTE User Plane
- Displays a topology view of the LTE user plane.
- LTE S1-U
- Displays a topology view of LTE S1-U connectivity.
- LTE S5-U
- Displays a topology view of LTE S5-U connectivity.
- LTE S8
- Displays a topology view of LTE S8 connectivity.
- LTE S1-MME
- Displays a topology view of LTE S1-MME connectivity.
- LTE S10
- Displays a topology view of LTE S10 connectivity.
- LTE S11
- Displays a topology view of LTE S11 connectivity.
- LTE SGi
- Displays a topology view of LTE SGi connectivity.
- LTE Gx
- Displays a topology view of LTE Gx connectivity.
- LTE S3
- Displays a topology view of LTE S3 connectivity.
- LTE S4
- Displays a topology view of LTE S4 connectivity.
- LTE S6a
- Displays a topology view of LTE S6a connectivity.
- LTE S13
- Displays a topology view of LTE S13 connectivity.
- LTE X2
- Displays a topology view of LTE X2 connectivity.
- IMS Control Plane
- Displays a topology view of IMS Control Plane connectivity.
- IMX CX
- Displays a topology view of IMX CX connectivity.

Click OK.
The new view is added to the navigation tree in the Navigation
Panel. If you added the view to a container, expand the container node to see the new
view in the tree.
Sample filters
The following examples show the different ways to build a typical filter. The filter retrieves
all Cisco devices on subnet 172.20.10.
To build a filter by typing SQL WHERE statements:
- On the Filter tab, from the Table list, select
ipEndPoint. In the Value field, type subnet like
'172.20.10.%'.
- Click Add new row
.
- From the Table list, select chassis. In the
Value field, type className like 'Cisco'.
- Click OK.
To build a filter by using the Filter Builder:
- On the Filter tab, from the Table list, select
ipEndPoint. Click . The Filter Builder is displayed.
- On the Basic tab, select subnet from the
Field list.
- From the Comparator list, select =.
- In the Value field, type 172.10.10.6 and click
OK.
- On the Filter tab, from the Table list, select
chassis. Click .
The Filter Builder is displayed.
- Click Add new row
.
- From the Field list, select className.
- From the Comparator list, select =.
- In the Value field, type Cisco.
- Click OK.
