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:
Use the links on the CiscoWorks Blue home page to start one of the Maps applications.
Note 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 displays the APPN page, with which you can view APPN network and local topology, as described in the "Displaying APPN Networks on the Web (Maps)" section. The APPN 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.
Note You must have a license for CiscoWorks Blue Maps to view the APPN page. Ask your Network Administrator for details.
This section provides information on displaying the APPN page from a web browser and viewing the nodes and transmission groups (TG) that make up the APPN network topology. This section includes the following subsections:
This topic describes how to use the APPN page. From the CiscoWorks Blue home page, click APPN. The APPN page is displayed. The APPN page is shown in Figure 3-1.
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 displaysthe Network Topology page, which shows the summary information about the APPN 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 displaysthe APPN 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
The APPN web pages contain several kinds of hypertext links to help you navigate through the topology information. When you click a hypertext link, APPN displays more information about the item that you clicked. The APPN pages use the following hypertext links:
When you click this...
APPN displays this...

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
This topic explains how to display a summary of all nodes and TGs with the same status. When you select Network Topology from the APPN page, the Network Topology page displays the summary information about the nodes and TGs. It lists the number of nodes in each node state and the number of TGs in each TG state. The Network Topology page contents are described in the following subsections:
When you display the Network Topology page, the box in the upper-right corner displays the name of the topology agent. If no topology agent was found, the box displays the message "No topology agent."
The Node List page includes a list of all nodes that have the same state. For each node state present in the network (unknown, degraded, active, and virtual routing nodes) there is a Node page that shows all the nodes in the specified state. There are up to four node pages, one for each possible state:
Unknown Node page—A node is unknown when the node state cannot be determined because the node is not managed, and there is neither a network topology agent nor an active CP-CP session path from the network topology agent to the node.
Degraded Node page—Degraded nodes are in the quiescing or congested state. A node has a degraded state if DLUR is configured but there is no DLUS session, or the node is reporting congested traffic.
Active Node page—Active nodes are enabled for APPN and are either being managed directly, or have an active CP-CP session path to the network topology agent.
Virtual Routing Node page—A virtual routing node is a representation of a set of node's connectivity to a connection network, such as a Token Ring, displayed as a single node.
When you display a Node List page, the box in the upper-right corner displays the name of the topology agent. Each Node List page contains a menu bar and a Node table.
Node List Page Menu Bar
The menu bar on each Node List page contains the following items:
The TG List page contains a list of all TGs that have the same status. For each TG state present in the network there is a TG page showing all the TGs in the specified state. There can be up to three TG pages, one for each possible state:
Unknown TG page—TG state cannot be determined because the node that owns the TG is not managed, and there is neither a network topology agent nor an active CP-CP session path from the network topology agent to the node that owns the TG.
Active TG page—TG is available for APPN sessions, as reported by either the node that owns the TG or the network topology agent.
Inactive TG page—TG is not available for APPN sessions, as reported by either the node that owns the TG or the network topology agent.
Degraded TG page—CP-CP session is defined but not active.
When you display a TG List page, the box in the upper-right corner displays the name of the topology agent.
For each TG state present in the network, the summary page shows a table that displays the source node and destination node for each TG in a TG state. There are up to three TG tables, one for each possible TG state:
Unknown
Active
Inactive
Degraded
