3.2.1 Configuration Parameters for ICP_IP Virtual Devices

ICP_IP virtual devices behave just like physical ICP boards except that they send and

receive data via an IP network rather than via a serial line. This section describes the

parameters in the boot configuration file used for ICP_IP devices. These parameters

specify the configuration of the IP link implemented by an ICP_IP device (for example,

the IP addresses and ports, data format, and so on). Each ICP_IP device may be config-

ured independently of all other ICP_IP devices.

The

bootcfg.ip file contains examples of the ICP_IP parameters. This file is preconfig-

ured with the following devices:

icp0 Commented-out examples of an ICP2424, ICP2432, and ICP6000

icp1 ICP_IP stream listening socket (TCP/IP server)

icp2 ICP_IP stream connecting socket (TCP/IP client)

icp3 ICP_IP datagram socket (unicast)

icp4 ICP_IP datagram socket (multicast)

Edit the

freeway/boot/bootcfg.ip file, modifying the following fields as necessary to set up

each ICP_IP virtual device:

Device Name The

device_name parameters in the example file in the bootcfg.ip file are

icp0 through icp3. Freeway uses the device names to identify the devices. If a Free-

way client uses the data link interface (DLI), the device name must be of the form

“

icpx”, where x corresponds to the BoardNo parameter in the DLI configuration

file,

freeway/client/test/ppp/pppaldcfg

. Each device name entered in the boot con-

figuration file must be unique. (Remember that the

ppp variable specifies the par-

ticular protocol or toolkit you are using. Refer to Ta bl e 2–2 on page31.)

Device Type The

device_type parameter for ICP_IP virtual devices must be icp_ip.
