This chapter describes the use of the Network Browser application which is launched from the CWM desktop. The Network Browser application provides a hierarchical representation of network information in a table format.
Each network element managed by Cisco WAN Manager (CWM) has its own attributes and fits in the network's physical or logical hierarchy. In CWM 9.2, the Network Browser presents the network elements that are discovered, managed, and controlled in a hierarchical view for all networks populated in the network table by CWM processes. The network element's attributes are presented in a table format.
The Network Browser displays the network elements in a hierarchical format based on either a physical or logical relationship among the various network elements. Networks are displayed at the root level of the component tree, and nodes and trunks are displayed beneath the networks in a parent/child relationship.
The Network Browser also displays informational and error messages in a multi-line text display. Other types of messages can be displayed in response to user actions.
To launch the Network Browser application, start CWM core processes (if necessary) and the CWM Desktop. Click the Network Browser icon to launch the application. Figure 7-1 shows the Network Browser when the application is launched for the first time.
The left pane displays Network1 (or the network you have configured in the config.sv file) shown in compacted form. The right pane indicates in tabular form the network name, upgrade status, and whether the NWIP is set on or off.
When you select Browser at the top of the left pane, the application fetches all networks in the database and displays them in the left pane.
Due to the width of the node table display, not all columns can be displayed at one time. Use the horizontal scroll bar to view undisplayed columns. A nodes table provides the following information as explained in Table 7-1.
| Column Heading | Meaning |
|---|---|
Node Name | Name of the node |
Alarm State | Node alarm status shown in text and color;
|
Management State | Management state of the node (reachable or unreachable) |
Synchronized | Yes if node is synchronized; otherwise, no |
Revision | Switch software revision running on node |
Network IP Address | Network IP Address |
LAN IP Address | LAN IP Address (not applicable to all nodes) |
Model/Type | Model string (if available) or type of node |
Protocol | Protocols running on the node; if the node supports both PNNI and AutoRoute, it will show AutoRoute, PNNI |
When you expand the network icon in the left pane of the network browser, it displays a window like that shown in Figure 7-2.
The first level of the network browser display lists routing nodes and routing trunks. Selecting routing nodes will display all the routing nodes in the network. Selecting routing trunks will display all of the routing trunks in the network. As you go deeper into the network resources, you will also be able to display information about front and back cards, ports, and lines, including VSI partitions.
When you click on a type of resource under individual switches as shown in Nodes Table,
Figure 7-2, the resource is expanded and information about the resource is displayed. In this example, clicking on Routing Nodes displays an expanded view of all routing nodes in Network1. By clicking on one of the resources listed under each node, you can display cards, feeder nodes, and access nodes of each switch.
The trunks table shows all trunks in a network and their resources and attributes, including cards, ports, and lines. As in the Nodes Table, clicking on one of the displayed resources in the trunks Table expands the resource and displays all available information about it.
Due to the width of the trunk table display, not all columns can be displayed at one time. Use the horizontal scroll bar to view undisplayed columns. A trunks table provides the following information as explained in Table 7-1.
| Column Heading | Meaning |
|---|---|
Name | Trunk Endpoints of format name:slot:port |
Alarm Status | Trunk alarm status shown in text and color
|
Interface | Trunk interface |
Line Load | Trunk Line Load |
Stat Reserve | Statistics Parameter |
Protocol | AR or PNNI |
PNNI Link Status | Up or Down |
Figure 7-4 shows more network resources displayed by the network browser, including lines and ports.
CWM uses color to display alarm situations detected by the Network Browser. Figure 7-5 shows the colors and the alarms they represent.
Using the Network Browser Edit Menu, you can define filters for nodes or trunks to view only selected elements. To filter certain resources, you must first select the type to filter, beginning with routing nodes or routing trunks, then specifying the exact type of resource to filter. After specifying the resources for which to filter, only those resources are displayed in the network browser.
You can define node filtering for any node element in your network from routing nodes and routing trunks to individual card types or node names beginning with a certain prefix. You can set up filters for all nodes or specify one of the following types:
You can define node filtering for PNNI, AR, or all protocols. You can filter for all switches, all cards, certain cards, or certain interfaces. Node synchronization can be set to Yes, No, or Both.
You can define trunk filtering for all trunks, PNNI, or AR.
