Physical Interface Numbers; Assigning Numbers To Fddi Interfaces - IBM 9077 Get Connected

• By a logical interface number assigned after the SAS/DAS settings are
numbered (used in the /etc/grifconfig.conf file)
• By a unique IP address assigned to each logical interface
Figure 46 shows files where various numbers are used to configure the
interfaces on an FDDI media card.

4.4.3 Physical Interface Numbers

The physical interface number identifies the specific FDDI fiber optic
attachment component according to its location on the media card; it may be
from 0–3.
Starting at the top of the media card, each physical interface is numbered
consecutively, beginning with 0, as shown in Figure 47 on page 128.
