Figure 47. Physical Interface Numbering on the FDDI Media Card

The diagram shows physical interface numbering to be 0-based (0–3), whereas SNMP numbering is 1-based (1–4).

4.4.4 GRF Interface Name

The GRF interface name has five components that describe an individual FDDI interface in terms of its place on the media card and in the GRF router.

Follow the naming conventions shown in Figure 48 and keep in mind that all interface names are case sensitive and that you must use all lowercase.

The interface name and IP address are specified in the /etc/grifconfig.conf file.

4.4.5 Configuration Files and Profiles

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

Proceed as follows:

1. Identify each logical interface.
