Flowchart 2 Procedures
NOTE Before proceeding to flowcharts 2 through 4, the Configuration Test
flowcharts, be sure that your connectors to the card, wall plug, and
TAU/Switch are fully connected.
A. Execute lanscan. Execute lanscan to display information about
Token Ring cards that are successfully bound to the system. For
example, to check the cards on HP-UX, enter: lanscan.
B. Is your Token Ring interface displayed and correct? lanscan is
successful if the output shows information about every networking
card in the hardware backplane whether the card state is UP or
DOWN. The Hardware Path of one of the entries should correspond
to your Token Ring card. Token Ring cards are identified by the MAC
type 802.5.
C. Run ioscan -f. ioscan -f will scan the system hardware and list the
results. LAN output similar to the following will be displayed:
The hardware path is four times the module number of the location
where the card is installed.
D. Is driver in kernel? If the driver has not been generated into the
kernel, ioscan output will be:
