Diagnosing Problems in the Hardware Configuration
If you suspect that a problem is due to an error in your hardware configuration (for example, when using a
LAN Emulation server, 8282 host, 25 Mbps client, and so on), check the following:
If the attached device is an 8282 host, enter the SHOW PORT command to see if the port's status is
UP
. If the status is not
UP
, follow the troubleshooting steps in the
IBM 8265 Media Module Reference
Guide, SA33-0459.
If a trap or error message is displayed on the client when you start the 8265, enter the SHOW PORT
command to make sure that the media port's status is
UP
. If the status is not
UP
, restart the client.
If the port's status does not change to
UP
, run a trace by entering the SET TRACE and UPLOAD
INBAND commands. Then contact your IBM service representative.
Use the MIB browser or the Campus Manager - ATM Version 2 for AIX to make sure that the client
addresses are configured in the 8265's ATM address table.
If the media port's status does not change to
UP
, contact your IBM service representative.
If the attached device is a LAN Emulation server (LES), make sure that it is installed and running
properly, and that:
– The status of the port that connects the LES to the 8265 is
UP
.
– The LES is configured with the ATM network prefix used by the 8265.
