CiscoWorks Blue Maps includes an interface that 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 Macintosh, a PC running Microsoft Windows or OS/2, or a UNIX workstation.
This chapter contains the following major sections:
Before you use access Maps from a web browser, ensure that the http server (httpd) is running on the workstation on which the CiscoWorks Blue Maps applications are installed. To determine whether an http server is running, enter the following command at the workstation:
% ps -ef | grep httpd
If the CiscoWorks Blue http server is not running, you can start it with this command:
% $CWBROOT/etc/cwbhttpd_start.sh
The CiscoWorks Blue http server starts using port 80. If port 80 is already in use, the CiscoWorks Blue http server starts using port 1742.
If the CiscoWorks Blue http server is running, you can stop it with this command:
% $CWBROOT/etc/cwbhttpd_stop.sh
We recommend that you use the http server provided as a part of CiscoWorks Blue. However, if you have configured CiscoConnect as part of CiscoWorks, you should use the CiscoConnect http server instead.
To start the CiscoWorks CiscoConnect httpd server, use this command:
% $NMSROOT/etc/start_httpd
If you are using any http server other than the one provided with CiscoWorks Blue, then use the following procedure to link the http server to the CiscoWorks Blue home page:
Step 1 Locate the configuration file for the httpd server that you are using.
Step 2 Search the configuration file for the DocumentRoot setting in the srm.conf or resource.conf file. Change to the directory listed for DocumentRoot.
Step 3 Use the following command to create a link:
% ln -s $CWBROOT/htdocs cw-blue
The CWBROOT environment variable is the path to where the Maps application is installed, usually /opt/CSCOcb or /usr/cw-blue.
Step 4 Search the configuration file for the ScriptAlias setting in the resource.conf or srm.conf file and note the directory listed as the ScriptAlias for /cgi-bin/.
Step 5 Change to the directory listed as the ScriptAlias for /cgi-bin/.
Step 6 Enter the following command to create a link:
% ln -s $CWBROOT/cgi-bin cw-blue
Step 7 Search the configuration file for the following line:
AddType text/x-server-parsed-html.htm
If you do not find this line, add it anywhere in the configuration file.
Now you can use a web browser to access the CiscoWorks Blue web interface as described in the following section, "Accessing Maps with a Web Browser."
This section describes how to access the CiscoWorks Blue Maps web interface with a web browser.
You can access CiscoWorks Blue Maps from any web browser in the network. The Universal Resource Locator (URL) that you specify depends on whether you are using the CiscoWorks Blue web server or the CiscoConnect web server.
To access the CiscoWorks Blue Maps web server, use one of the following URLs:
http://workstation/cw-blue/cwblue.html
or
http://workstation[:port_number]/cw-blue/cwblue.html
Where:
workstation is the IP address or host name of the workstation on which you installed CiscoWorks Blue Maps.
port_number is the CiscoWorks Blue web server port. The default is port 80. However, if port 80 is already in use, the CiscoWorks Blue web server uses backup port 1742. If the server is using port 80, you can omit this option. If the server is using port 1742, you must specify it with this option. For example, if you installed maps on a workstation with the address wwwblue.company.com, you would set your browser to the following URL:
http://wwwblue.company.com/cw-blue/cwblue.html
To access the CiscoWorks CiscoConnect web server from a web browser, use the following URL:
http://workstation:port_number/cw-blue/cwblue.html
Where:
workstation is the IP address or host name of the workstation on which you installed CiscoWorks CiscoConnect.
port_number is the CiscoWorks CiscoConnect web server port, which you configured during installation. The default is port 22854.
For example, if you installed CiscoConnect on a workstation with the address wwwblue.company.com, using port 22854, you would set your browser to the following URL:
http://wwwblue.company.com:22854/cw-blue/cwblue.html
You can start a a web browser from the Maps Tools menu. To start the Maps web browser, select Tools>Web Browser from the Maps application menu bar.
If you have problems, review the $CWBROOT/etc/runweb script to ensure that the setting of environment variables, the name of the web browser, and the path to the web browser match the directory structure on your workstation. You can modify the
$CWBROOT/etc/runweb file with any editor, such as vi.
vi $CWBROOT/etc/runweb
When the web browser finds the CiscoWorks Blue URL, it displays the CiscoWorks Blue Network Management home page, as shown in Figure 9-1.
Click one of the buttons in the Request field and click the Send Request button.
All pages displayed by the http interface are static pages. They are not updated dynamically. To update the information on a web page, click the Reload button on your web browser.
When you click Reload, the web server collects its data from the database or from the network devices, depending on which web page you are displaying. For example, when you click Reload on the APPN Network Topology page, the web server collects data from the network topology agent in the network.
This section describes how to display the APPN Network Management page from a web browser and how to view the nodes and transmission groups that make up the APPN network topology. It contains these sections:
This section describes how to view the APPN Network Management page. From the CiscoWorks Blue Network Management home page, click APPN. The APPN Network management page is displayed, as shown in Figure 9-2.
First you identify a network topology agent. The network topology agent provides the APPN topology information. You can specify the network topology in either of the following ways:
When you first refer to a network topology agent, use its IP address and read community string. The APPN application correlates the IP address with the network node's NETID.CPNAME. In the future, you can use just the NETID.CPNAME.
Now click one of the buttons in the Request field and click Send Request.
Click Send Request to display the requested page.
The APPN web pages described in the following sections contain several kinds of hypertext links to help you navigate through the topology information.

This section describes how to display the Manage SNA Resources page from a web browser and how to view the PUs and LUs in the network. It contains the following sections:
This section describes how to display and manage PUs and LUs from a web browser. Select SNA Resources (PUs and LUs) from the CiscoWorks Blue Network Management home page. The Manage SNA Resources page is displayed, as shown in Figure 9-5. Use the Manage SNA Resources page to determine whether to display DLSw or RSRB resources, whether to display PUs and LUs, and how to filter the PU or LU names.
Select one of the buttons in the "Protocol" field:
Select one of the buttons in the "Resource Type" field:
Select one of the buttons in the "Request" field and click Send Request.
This section provides more detail to help you choose the VTAM information, shown in Figure 9-5, with which to filter the PU or LU names to be displayed. You selections will differ depending on whether you display PUs or LUs. In each case, you define a set of filtering criteria to select the PUs or LUs you want to view.
First, choose the VTAM information to use as filter criteria:
You can configure a filter, as shown in Figure 9-5, to select the PU names to be displayed based on the VTAM information. Use the following procedure to choose which PUs to display based on the VTAM characteristics of the PUs.
Step 1 Use the "PU Name" field to display all PUs with a shared naming convention. You can use wildcards in this field. Use one of the following formats:
Step 2 Use the "Select Resource State" field to display all PUs with the selected PU states:
If you select all states or no states, state filtering is bypassed and all PUs are displayed.
Step 3 Use the "Select PU Type" field to choose one or more PU types to display. You can select any number of these PU types: 1, 2, 2.1, 4, or 5. If you select no PU type, or if you select all the PU types, PU type filtering is bypassed and all PUs are displayed.
You can configure a filter, as shown in Figure 9-5, to select the LU names to be displayed. Use the following procedure to choose which PUs to display based on the VTAM characteristics of the PUs.
Step 1 Use the "PU Name" field to display all LUs associated with one or more PUs. Use one of the following formats:
Step 2 Use the "LU Name" field to display all LUs with a shared naming convention. You can use wildcards in this field. Use one of the following formats:
Step 3 Use the "Select Resource State" field to display all LUs with the selected PU states:
If you select all states or no states, state filtering is bypassed and all LUs are displayed.
The SNA Resources web pages described in the following sections contain several kinds of hypertext links to help you navigate through the network information. Table 9-30 shows the hypertext links commonly used on SNA Resources pages.

PU name | Dependency view for PU and a list of LUs under that PU |
The SNA Resources page displays the following information for PUs:
The SNA Resources page displays two tables for LUs:
| Output Field | Description |
|---|---|
Inactive displays the total number of PUs or LUs whose VTAM status is INACT. Active displays the total number of PUs or LUs whose VTAM status is ACTIV. Connectable displays the total number of PUs or LUs whose VTAM status is CONCT. Pending displays the total number of PUs or LUs whose VTAM status is a PENDING status. Never active displays the total number of PUs or LUs whose VTAM status is NEVAC. Other displays the total number of PUs or LUs with some other VTAM status. Unknown displays the total number of PUs or LUs with no reported status. | |
Number of PUs/LUs | The number of PUs or LUs of this connection state that meet the criteria that you specified. |
