4.2.2 Installing Configurations or Changes

In the command line interface (CLI), use set and write commands to install configuration parameters.

To save the /etc configuration directory, use grwrite -v.

Additionally, when you enter configuration information or make changes, you must also reset the media card with the command grreset <slot_number> for the change to take place.

4.2.3 Configuration Files and Profiles

Following are the steps to configure an ATM card. They are listed here complete, although you can bring up an ATM connection with a subset. For detailed information, see GRF Configuration Guide 1.4, GA22-7366.

Proceed as follows:

1.Identify each logical interface.

Edit grifconfig.conf, to identify each logical interface, by assigning:

•An IP address

•The GRF interface name

•A netmask, as required

•A destination or broadcast address, as required

•An MTU, if needed

See Section 4.2.4, “Assign IP Addresses - grifconfig.conf” on page 114 for the details.

2.Specify ATM card parameters in the Card profile (all optional):

•Specify ICMP throttling settings

•Specify a selective packet discard percentage in the spd-tx-thresh field

•Change run-time binaries

•Change dump variables

3.Configure PVCs and SVCs in /etc/gratm.conf.

Edit the file /etc/gratm.conf and add entries for the following keywords for a minimum configuration:

•Traffic_Shape

•Interface

•PVC
