Problems with Hardware Configuration
If you suspect that a Phase 3 problem is due to a problem in your hardware configuration (for example,
using a LAN Emulation server, 8282 host, 25Mbps client, and so on), follow the troubleshooting
procedures listed below.
Possible problem with hardware configuration
Steps to Take:
1. If the attached device is an 8282 host, enter the SHOW PORT command to see if the port's status is OKAY . If the
status is not OKAY , follow the steps in “Problems with Configuring Ports” on page 159.
2. If a trap or error message is displayed on the client when you start the workgroup switch, enter the SHOW PORT
command to make sure that the ATM media port's status is OKAY . If the status is not OKAY , restart the client.
If the port's status does not change to OKAY , run a trace by entering the SET TRACE and UPLOAD INBAND
commands. Then contact your IBM service representative.
3. Use the MIB browser or the ATM Campus Manager for AIX Version 1 to make sure that the client addresses are
configured in the workgroup switch’s ATM address table.
If the ATM media port's status does not change to
OKAY
, contact your IBM service representative.
4. If the attached device is a LAN Emulation server (LES), make sure that it is installed and running properly, and
that:
Ÿ The status of the port that connects the LES to the workgroup switch is OKAY .
Ÿ The LES is configured with the ATM network prefix used by the workgroup switch.
