18Chapter 4 Board and System Configuration

When frame relay is used, after creating and editing the ifcfg-pvcN file(s) for the PVC(s), execute the

command

pc300up pvcN

to activate each PVC.

The command

ifconfig

(without parameters) will show the status of all activated ports. Each hdlcN

device should be listed separately (one per port).

STEP FIVE

For the Linux to function as a router, routing must be enabled. This can be done by executing the following

command:

echo 1 > /proc/sys/net/ipv4/ip_forward

To make this effective every time the system is booted, include the line above in one of the scripts run during

initialization (in /etc/rc.d). Some distributions provide a configuration interface to set this parameter (such as

linuxconf.) Refer to the Linux distribution documentation.

Reboot the system and inspect the boot messages. The driver should report the PC300 boards detected.

Cyclades-PC300 driver <version> <date> built <date>

hdlc0: PC300/RSV #1, 256KB of RAM at 0xMMMM, IRQn, channel 1.

hdlc1: PC300/RSV #2, 256KB of RAM at 0xMMMM, IRQn, channel 1.

etc.

At this point the installation of the board is complete.
