▼To Check the SunFDDI/P Driver
♦Use netstat(1M) to check that the SunFDDI/P (pf) driver is installed
correctly,and to check for an excessive number of errors and collisions:
A sudden increase in the number of errors could indicate a noisy connection
caused by a dirty cable.
▼To Check the IP Addresses
Youmust assign a unique IP address to each SunFDDI/P interface. If you have
more than one IP interface installed in your machine—either multiple
SunFDDI/P interfaces, or some other LAN interface (for example, an Ethernet
interface)—each interface must be attached to a different subnetwork.
♦Use ifconfig(1M) to check the IP addresses assigned to the two
SunFDDI/P interfaces:
If the interfaces have the same subnetwork number,as shown in this example,
you must change the IP address assigned to one of the interfaces.
Ensure that the IP addressesand host names for each SunFDDI/P interface are
entered in the NIS map, or in /etc/hosts on the local machine if you are not
using NIS/NIS+.
