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.
