- Look for the value of Operation Status. It should say “DOWN”.
• Ensure that the host system contains the correct patch level. To find
out which version of the driver is currently installed, execute the
command:
what /stand/vmunix | grep btlan
Or use the command:
swlist -l product | grep 100
This should display an ASCII string that indicates the Version and
possibly Patch level of the driver. Many problems have been resolved
with newer versions of the driver, which can be obtained from the
latest patches for the 100Base-T cards along with any dependent
patches. Work with the Response Center to determine if there is a
newer driver that fixes the symptoms of the problem you are facing.
There are three types of patches that are recommended:
- Patches for software driver
- Patch(es) for lanadmin - current lanadmin provides the
lanadmin -x -X functionality.
- Pacth(es) for SAM - all systems need an updated SAM patch
because SAM can “step on” the 100Base-T configuration file
Duplex mode.
• Display the card’s current speed and duplex, issue the command:
lanadmin -x NMID/PPA (nmid/ppa comes from the lanscan
command)
