Flowchart 4 Procedures
A. Execute ifconfig <interface> <IP address> up. Execute ifconfig
on the interface you want to test to be sure that the interface is
enabled. For example, to check Token Ring interface lan1, enter:
ifconfig lan1 192.6.1.17 up
For more examples of the ifconfig command, refer to the ifconfig(1M)
on-line man page.
B. Execute ifconfig <interface>. Execute ifconfig again on the
interface you want to test to check the flag setting is up. For example,
to check Token Ring interface lan1, enter:
ifconfig lan1
C. ifconfig successful? ifconfig is successful if the output shows the
correct Internet Address and the flags: <UP, BROADCAST,
NOTRAILERS, RUNNING>.
For PCI Token Ring, the flags are: <UP, BROADCAST, RUNNING,
MULTICAST>.
Note: Make sure the UP flag is displayed. Running is always
displayed in ifconfig(1M). It indicates only that there is OS support
for the interface.
D. Any error message returned? If ifconfig is not successful, check
whether an error message appears.
E. Problem fixed? If so, stop. If not, go to K.
F. ifconfig parms in /etc/rc.config.d/netconf? Check that the Token
Ring parameters for ifconfig(1M) are in the /etc/rc.config.d/netconf
file for your Token Ring network interface. Refer to the Installing
and Administering LAN/9000 Software manual for information on
netconf. Refer toChapter 3, Token Ring Resources, in this manual for
a Token Ring example of this command.
G. Add ifconfig parms to /etc/rc.config.d/netconf file. Add the
ifconfig command to /etc/rc.config.d/netconf. For more information,
refer to the instructions in the netconf file under Internet
Configuration Parameters.
H. Problem resolved? If so, stop. If not, recheck your connections to
the wall plug and TAU. If the problem is still unresolved, go to
