Left Pane Filters in the Topology Map Window

 

The Left Pane Filters are used to change what is displayed in the topology map. From the Filters menu you can select Protocols, Types, Routing Instances, or Advanced.

To access the available protocol filters, select Filters > Protocols. The Filters > Protocols view is displayed as shown in Figure 1.

Note

You can also access this view by navigating to Subviews > Protocols.

Topology Map Window

The Protocols view allows you to display subsets of the available network routing protocols in the network using logical operations like AND, OR, NOT, and EQUAL. The protocols available vary according to the protocols in the model network.

Selecting Show by itself displays all network elements supporting the protocol. Selecting Show and Not together for a protocol displays all network elements that do not support the protocol.

You can perform logical operations on the protocol list selections. The equal operation (=) specifies that only the currently selected view is shown. Only one selection is allowed for this operation. The AND operation (&) specifies that the intersection of the protocol views is displayed. The OR operation (or) specifies that the union of the protocol views is displayed.

Table 1 presents examples of how to interpret the Protocols view.

=

OSPF

Filters the display to show OSPF-enabled links.

&

OSPF: Show

MPLS-TE: Show + Not

Filters the display to show all links with OSPF enabled but without MPLS enabled.

or

OSPF: Show

ISIS: Show

Filters the display to show all links with either OSPF or IS-IS enabled.

The Filter Summary at the bottom of the window contains the number of nodes, pseudo-nodes, groups, and links that are currently displayed out of the total number. The number displayed is less than the total when objects are hidden due to selections either in this pane or other filter panes.

To access the filters related to node or link types, select Filters > Types. The Filters > Types view is displayed as shown in Figure 2Figure 2.

Note

You can also access this view by navigating to Subviews > Types.

Select the check boxes beside the types you want included in the topology map display. Deselect those you want omitted.

Select Filters > Routing Instances. The Filters > Routing Instances view is displayed as shown in Figure 3.

Note

You can also access this view by navigating to Subviews > Routing Instances.

There is a Filter Summary at the bottom of the window that displays the number of nodes, pseudo-nodes, groups, and links that are currently displayed out of the total number. The number displayed is less than the total when objects are hidden due to selections either in this pane or other filter panes.

To access advanced filters in the left pane, select Filters > Advanced. The Advanced Filters view is displayed as shown in Figure 4.

Option

Description

Recorded Selection > Show Only Recorded

Allows you to select some nodes or links on the map and then click Record to take a snapshot of the selection. After the recording is made, selecting this check box shows only the recorded selection.

Recorded Selection > Hide Recorded

Allows you to select some nodes or links on the map and then click Record to take a snapshot of the selection. After the recording is made, selecting this check box hides the recorded selection from the map.

AS > Show Only Selected ASs

Allows you to show only selected autonomous systems (ASs) in the topology map. Click Select to specify which ASs to show.

Intragroup Links > Hide All

Intragroup Links > Hide Tier 2

Intragroup links connect nodes within a group. If there are several layers of groups, selecting Intragroup Links > Hide All hides all links within the top-level groups, and selecting Intragroup Links > Hide Tier 2 hides all links within groups that are two group levels down.

Advanced Filter

Click Set for one of the three categories (Node, Group, or Link) to create an advanced filter statement. Then use the check box to turn the filter on or off.

Hide Isolated Points

Hides nodes and groups that are disconnected from all other nodes and groups in every subview in the map.

Hide Isolated Points in Subview

Hides nodes and groups that are disconnected from all other nodes and groups in the current subview.

Hide AS Nodes/Links

Hide AS nodes and links in the current topology.

Hide Backup

Hides backup routes in the topology.

Hide VT

Hides virtual trunks in the topology.

Hide Intergroup Links

Hides intergroup links connecting different groups.
