Using the CiscoWorks Blue Home Page to Display Maps

This chapter provides information about the interface you can use to display network map information from a web browser, such as the Netscape Navigator or Microsoft Internet Explorer. This interface provides, in tabular format, functions similar to those provided by the standard Motif interface. You can access Maps information from any web browser on any workstation platform, such as a PC running Microsoft Windows or a UNIX workstation.

This chapter includes the following main sections:

Using the Link on the Home Page

Use the links on the CiscoWorks Blue home page to start one of the Maps applications.

Depending on whether you have licensed Maps or SNA View or both, the appropriate icons are active. The icon for any program you have not licensed is inactive.

APPN/SNASw displays the APPN/SNASw page, with which you can view APPN/SNASw network and local topology, as described in the "Displaying APPN/SNASw Networks on the Web (Maps)" section. The APPN/SNASw web page requires a license for CiscoWorks Blue Maps.
DLSw displays the DLSw page, with which you can view the DLSw network devices, as described in the "Displaying DLSw Networks on the Web (Maps)" section. The DLSw web page requires a license for CiscoWorks Blue Maps.
RSRB displays the RSRB page, with which you can view the RSRB network devices, as described in the "Displaying RSRB Networks on the Web (Maps)" section. The RSRB web page requires a license for CiscoWorks Blue Maps.

For information on Web Browser Conventions, see "Using the CiscoWorks Blue Home Page."

Displaying APPN/SNASw Networks on the Web (Maps)

Note You must have a license for CiscoWorks Blue Maps to view the APPN/SNASw page. Ask your Network Administrator for details.

This section provides information on displaying the APPN/SNASw page from a web browser and viewing the nodes and transmission groups (TG) that make up the APPN/SNASw network topology. This section includes the following subsections:

APPN/SNASw Page

This topic describes how to use the APPN/SNASw page. From the CiscoWorks Blue home page, click APPN/SNASw. The APPN/SNASw page is displayed. The APPN/SNASw page is shown in Figure 3-1.

Figure 3-1 APPN Page

You can perform the following on the APPN/SNASw page:

Click Network Topology to display the Network Topology page.
Enter the IP address (host name) and the read community string, or just the CP name, of a network node to display the Node Details page for that node.

Click one of the buttons in the Request field to review the following information:

Network Topology displays the Network Topology page, which shows the summary information about the APPN/SNASw network nodes and transmission groups. Use this selection to display a list of all nodes or all TGs that have the same status. See the "Network Topology Page" section for more information.
Node Details displays the APPN/SNASw Node Details page, which shows information about a specific node and the node's network connections. Use this selection to display detailed information about one node. See the "Node Details Page" section for more information

Click go to display the requested page.

Using APPN/SNASw Hypertext Links

The APPN/SNASw web pages contain several kinds of hypertext links to help you navigate through the topology information. When you click a hypertext link, APPN/SNASw displays more information about the item that you clicked. The APPN/SNASw pages use the following hypertext links:

When you click this...	APPN displays this...
Link Name	Link Properties page
NETID.CPNAME	APPN Node Details page
Port Name	Port Properties page
Node State	List of nodes in that state
TG Number	TG Properties page
Intermediate Session	Intermediate session page, including session route

Deleting Inactive TGs

A change to the Cisco IOS software deletes inactive dynamic TGs from the router database. If you want to keep those inactive TGs in the Maps and SNA View cache, set the keep_deleted_tgs option in the cwbinit file to on. The following keep_deleted_tgs option is new in the cwbinit file:

 
# This option controls the CWBlue cache deletion of TGs that are no 
# longer reported by local topology agents. A Cisco IOS change was 
# made to delete inactive dynamic TGs from the router database.

 
# To delete TGs that are no longer reported by the agent,

 
# set this parameter to 'off'. 

 
# To keep those TGs in the CWBlue cache, set this parameter to 'on'. 
# If TG events are enabled, this will trigger an event if the TG 
# becomes operational again.  

 
# valid values:on/off

 
keep_deleted_tgs = off

Rediscover Router Page

The Rediscover Router page lets you rediscover a router. Rediscovering a router reloads the Maps database with the SNMP information from the router. Click the router name to display the Focus View page for that router.

To rediscover a router, use the following procedure:

Step 1 Select Rediscover Router on the DLSw page.

Step 2 Enter the IP address or host name of the router as it appears in the database. (You can browse the DLSw Global View page to find the router and then select the Focus view for that router.)

Step 3 Click go. When the router is discovered, the Rediscover Router page is displayed, as shown in Figure 3-3.

Note When you are adding, discovering, or rediscovering routers, you can use the cwbsnamapsd and dlswpollerd commands to ensure the correct information is available for the discovered resources.
