Following Along with the Examples in this Manual
Many of the topics in this guide use a sample network to illustrate step by step procedures that you can follow along with. These networks are located in the $WANDL_HOME/sample folder on your server, where $WANDL_HOME is the directory in which the server was installed (typically /u/wandl). In the sample directory are two folders, “atm” and “router”. In the File Manager, navigate to the “router” folder and then a subdirectory, such as “fish”. Double-click on the “spec.mpls-fish” file. This opens the network project.
At this moment, you may encounter a popup message, as shown below. This message indicates that either you do not have an appropriate router license to open this network, or your license has expired.
To examine your license, view the npatpw file located on your server, in $WANDL_HOME/db/sys/npatpw. If your license has expired (see the line “expire_date=”), please contact Juniper support. Otherwise, proceed to the next step.
In this example, we will use the network in /u/wandl/sample/IP/fish to illustrate. If you see such a warning as in Figure 1, you will need to edit the sample network files slightly to accommodate the network hardware types for which you do have a license to. Because the sample network files are not writable, the following procedure is the simplest one to get your sample network up and running.
Log into your server machine. Then do the following at the prompt, denoted by “>” below:
> cd /u/wandl/sample/IP > cp -r fish fish1 > cd fish1 > chmod 666 *
The above commands first makes a complete copy of the fish folder into a new folder called “fish1”, and then changes the permissions of all the files so that they are writeable, or editable, by you.
Instead of “fish1”, you may wish to specify a different location. For example:
> cp -r fish /export/home/john/myexamples/fish
Now, return to your client application and navigate within the File Manager to the newly created folder. Right-click on the “spec.mpls-fish” file and select Spec File > Modify Spec from the popup menu.
Within the Spec File Generation window, click on the Design Parameters tab. Within this tab, press the “Reset dparam File” button. Click “Yes” to any popup dialog windows that appear at this time. Notice that the Hardware Type drop-down box is now enabled. Select a type from this drop-down box. What is displayed in this list will vary, depending on the hardware types present in your license. Most users will probably have only one or two types listed.
Press the “Done” button. The Specfile Status window will appear. In the Specfile Status window, click on the “Load Network” button. Press “Yes” to overwrite both the spec.mpls-fish and dparam.mpls-fish files. The sample network will now be launched successfully.
