entered for the interface. For example, if the IP address of the interface is 199.120.211.98, the portion of the menu displaying the available transmit broadcast addresses would appear as:

Transmit Broadcast Address:

1)199.120.211.255

2)199.120.211.0

3)255.255.255.255

4)0.0.0.0

5)Specify Explicitly

Enter Transmit Broadcast Address [default = 1]? 1

In almost all cases, the default transmit address is used (1). The only time any of the other numerical addresses are used is if the default has been configured, and the machines are not responding to IP RIP or some other broadcast protocol. If this happens, try the other Transmit Broadcast Address menu selections. Some older UNIX machines may work with selection (2) or (4). Regardless of which address is selected, the goal is to allow broadcasts from the defined interface to all devices on the local network.

If you plan to exchange IP RIP packets with devices connected over dedicated links or semi- permanent connections, select Specify Explicitly. You can then explicitly specify the device (only one) with which the CyberSWITCH will be exchanging packets. You may also select this option to support a unicast address feature for a numbered WAN interface. (See RIP Send Control options.) This will avoid sending packets to all remote devices on the IP network.

TRANSMIT BROADCAST IP ADDRESS

Requested only if you selected Specify Explicitly for the transmit broadcast address. The IP address of the device with whom the CyberSWITCH will be exchanging RIP packets.

For multiple LAN network interfaces, you must have an associated transmit broadcast address for each interface.

INPUT/OUTPUT FILTER NAME

A filter is a list of conditions which modifies the normal processing flow of packets. You may specify the name of a predefined input and/or output filter for the primary interface on a LAN port. All secondary interfaces assigned to the same LAN port are subject to the actions specified by these filters. When configuring a secondary LAN interface, you cannot change the filter information.

RIP INFORMATION

(See individual Send Control, Receive Control, Respond Control and Authentication Control elements). You may configure one set of RIP parameters for the primary network interface on a LAN port. All other secondary interfaces assigned to the same LAN port are subject to the same actions specified by these parameters. When configuring a secondary LAN interface, you cannot change the RIP information.

You may also configure a set of RIP parameters for each RLAN or numbered WAN interface.
