Flowchart 3 Procedures
A. Execute lanadmin. Access the lanadmin(1M) program by entering:
lanadmin.
For a complete description of the lanadmin command, refer to the
lanadmin(1M) on-line man page.
B. Select LAN from Menu. Select lan from the menu to enter LAN
Interface Diagnostic.
C. For HP-UX versions earlier than 10.30, select the NMID
command and enter the Token Ring NMID. Select the NMID
command to display the current Network Management ID. Then
enter the Network Management ID of the Token Ring device file such
as 5. You can use the lanscan command to find the NMID for your
Token Ring. The device represented by the NMID that you enter
becomes the current device to be tested. If you receive an error, look
at the UNIX error code.
For HP-UX versions 10.30 or later, select the PPA command and
enter the Token Ring PPA.
D. Select display command. A display of the Token Ring card status
and statistics will appear on the screen. The Token Ring display
shows a link type of iso8825-tokenRing(9).
E. Op. Status = UP? If the card operation statusis UP, continueto step
G. If the card is not UP, continue to step F. NOTE: If speed is
incorrect for PCI Token Ring, operation status may be down.
F. Resolve error condition. If the error code is Errno=(6,22,16), the
NMID used by lanadmin does not correspond to an active LAN card.
Using the NMID command in lanadmin, enter a valid NMID and
start again from step C.
If the operation status=DOWN, the LAN card is currently
inoperative.Reset the card, using the reset command in lanadmin,to
re-execute the LAN card self-test. If the test is successful, start again
with this flowchart to display LAN card statistics.
Another possibility is a bad cable. Check cable(s).
G. Is the card link speed correct? Check the Speed field in the
lanadmin status display to verify that the speed matches the speed
of the Token Ring network. Refer to Appendix A for definitions of the
lanadmin status fields.
