Advanced Configuration of Cisco Internet Junction
This chapter describes how to configure Cisco Internet Junction and includes the following sections:
You do not need these options unless you have multiple gateways.
If your site has multiple gateways, IJ client software performs automatic load balancing by picking a gateway from among those available. However, you can specify a client's preferred gateway---the gateway to which the client tries to connect at startup. Specifying preferred gateways can be useful for dividing the user community---for example, for administrative or accounting purposes. If the preferred gateway is unavailable, the client connects to any available gateway.
To specify a preferred gateway, you can either edit the client's WIN.INI file, or modify the IJ client executable command line or target property.
Take the following steps to edit the WIN.INI file:
[Internet Junction Client] Preferred Gateway = Any
If a Windows icon represents an executable program, its Properties window includes information that tells Windows how to start the program. This information is called the command line property in Windows 3.1 and Windows for Workgroups and the target property in Windows 95.
The following command line or target property starts IJCLIENT.EXE:
ijclient [-g gateway-name]
where gateway-name specifies the client's preferred IJ gateway.
For example, the following property causes the client to try to connect with the gateway Cloudy:
ijclient -g cloudy
If Cloudy is unavailable, the client connects to any available gateway.
To change the preferred gateway, edit the properties of the Cisco Internet Junction item. When the IJ client starts, it writes gateway-name into the WIN.INI file as the new value for the preferred gateway.
Sometimes a client may want to disconnect from one gateway and connect to another. For instance, your network could be configured so that one gateway provides Internet access and another provides internal TCP/IP access, and a client might want to switch between the two.
The Gateways menu in the IJ client window displays a list of known gateways. A check mark indicates the gateway to which the client is currently connected. The client software periodically refreshes the list, adding names as gateway SAP messages arrive, and removing the names of servers that stop sending SAP messages.
Take the following steps to change a client's current gateway:
When a client changes the current gateway, the new gateway automatically becomes the preferred gateway. The client software writes the gateway name into the WIN.INI file, and attempts to connect to that gateway the next time it starts.
The Cisco Internet Junction window for both the IJ client and the IJ gateway includes a Status menu item. This option provides information about the client or gateway software and its current connections.
When you first select the Status menu item, the display is static---status appears on the screen once and does not refresh itself.
Click again on the Status menu item to start a low-level tracing program that shows the transmission of SAP messages and routing information packet (RIP) messages. Generating a trace can be helpful if you need to troubleshoot a problem.
To stop the trace program, click again on the Status menu item. An updated static display appears.
