Troubleshooting the SWAN Concentrator and WAN Subsystem

6 Reconfigure the SWAN concentrator to use the new Ethernet adapter port.

Use the SCF STOP ADAPTER command to stop the SWAN concentrator:a.

STOP ADAPTER $ZZWAN.#<adapter-name>, SUB ALL

Use the SCF ALTER ADAPTER command to alter the appropriate NonStop TCP/IP

process.

To alter the preferred NonStop TCP/IP process, type the following:

ALTER ADAPTER $ZZWAN.#<adapter>,

TCPIP $<tcpip-process>,

HOSTIP <ip-address>

To alter the alternate NonStop TCP/IP process, type the following:

ALTER ADAPTER $ZZWAN.#<adapter>,

ALTTCPIP $<tcpip-process>,

ALTHOSTIP <ip-address>

<adapter> is the name of the SWAN concentrator.

<tcpip-process> is the name of the NonStop TCP/IP process that supports the

new Ethernet adapter port.

<ip-address> is the IP address associated with the NonStop TCP/IP process that

supports the new Ethernet adapter port. (You identified this IP address in Step 2.)

Use the SCF START ADAPTER command to restart the SWAN concentrator:c.

START ADAPTER $ZZWAN.#<adapter>, SUB ALL

Use the SCF STATUS ADAPTER command to verify that the SWAN concentrator is in

the STARTED state:

STATUS ADAPTER $ZZWAN.#<adapter>, SUB ALL

The example shows the output of this command.

Correcting the NonStop TCP/IP Process Configuration:

If the SWAN concentrator is configured to use the wrong NonStop TCP/IP process, you must reconfigure

the SWAN concentrator to use the correct NonStop TCP/IP process by performing the following steps:

Note: If there are active communications lines using the SWAN concentrator, you must stop them

using the SCF STOP LINE or SCF ABORT LINE command (for example, STOP LINE $LINE1). If you do

not know the names of the communications lines that are using the SWAN concentrator, use the SCF

STATUS ADAPTER command to identify them.
