Troubleshooting if the CLIP is Inaccessible

If the SWAN CLIP is inaccessible:

•

Ensure that the server state for the SWAN CLIP is in a STARTED state by issuing

the SCF STATUS TASK command:

SCF STATUS TASK $ZZWAN.#conc-name.clip-num.DIAG

If the CLIP is accessible, the status of the DIAG task is displayed. If the CLIP is not

accessible on either PATH, then an error is displayed.

•

The SCF STATUS TASK command also displays an EMS message indicating the

failure and reason for this failure. This provides a good start for finding out the

cause and the recovery for this problem. In most cases, the EMS message

indicates the cause directly (G06.07 and later RVUs).

•

The SCF STATUS SERVER command with the DETAIL option provides the path

health status. For more information, see Finding the Current PATH Status of the

CLIP on page 6-11 (G06.07 and later RVUs).

•

Execute the WANLNCK utility on one of the LINEs configured in the SWAN CLIP.

This utility verifies if the TCP/IP, TFTP, TRAPMUX, WANBoot, and ConMgr

processes are configured correctly. After verifying the configuration check,

WANLNCK also downloads the DIAG task to get the details from the CLIP.
