interface basis. This field is also used to specify ISO when an ISO address is being added to an interface’s IP address. Specify the MTU value as mtu xxxx. Leave the arguments field blank if you are not using it.

The following excerpt from our /etc/grifconf.conf file shows the format of an entry:

# name

address

netmask

broad_dest

arguments

ga010

10.1.1.1

255.255.255.0

-

mtu 9180

ga0180

10.1.2.1

255.255.255.0

10.1.2.2

 

As you can see, we have defined the first logical interface to be broadcast and the second interface to be point-to-point.

4.2.5 Specify ATM Card Parameters

Changing the following profile is not mandatory. You can safely use the defaults. Refer to GRF Configuration Guide 1.4, GA22-7366 if you intend to change settings.

4.2.6 Configuring PVCs

To configure a logical interface that supports PVCs, make entries in these configuration files:

1./etc/grifconfig.conf

Assign an IP address to the logical interface.

2./etc/grarp.conf

Supply IP-to-physical address mapping information for the ARP service.

Put an entry into /etc/grarp.conf only if the remote destination does not support InATMARP, which the GRF does.

3./etc/gratm.conf

Traffic shaping section

Set the traffic shaping name and quality of service parameters. The name may be any meaningful string you like.

Signaling section

Set protocol=NONE on the signaling entry for the appropriate card and connector combination.
