Correcting the TCP/IP Process Configuration
c. Restart the SWAN concentrator by using the SCF START ADAPTER
command:
START ADAPTER $ZZWAN.#adapter, SUB ALL
d. Verify that the SWAN concentrator is in the STARTED state by using the SCF
STATUS ADAPTER command:
STATUS ADAPTER $ZZWAN.#adapter, SUB ALL
Verifying That a SWAN Concentrator is Started on page A-30 shows the output
of this command.
Correcting the TCP/IP Process Configuration
If the SWAN concentrator is configured to use the wrong TCP/IP process, you must
reconfigure the SWAN concentrator to use the correct TCP/IP process by performing
these steps:
1. Reconfigure the SWAN concentrator to use the new TCP/IP process.
a. Stop the SWAN concentrator by using the SCF STOP ADAPTER command:
STOP ADAPTER $ZZWAN.#adapter, SUB ALL
b. Alter the appropriate TCP/IP process by using the SCF ALTER ADAPTER
command.
To alter the preferred TCP/IP process, type:
ALTER ADAPTER $ZZWAN.#adapter,
TCPIP $new-preferred-tcpip-process,
HOSTIP new-preferred-ip-address
To alter the alternate TCP/IP process, type:
ALTER ADAPTER $ZZWAN.#adapter,
ALTTCPIP $new-alternate-tcpip-process,
ALTHOSTIP new-alternate-ip-address
c. Restart the SWAN concentrator by using the SCF START ADAPTER
command:
START ADAPTER $ZZWAN.#adapter, SUB ALL
Note. If active communications lines are using the SWAN concentrator, you must stop them by
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 SERVER command (not the SCF STATUS ADAPTER) to
identify them.
Note. For pre-G06.06 RVUs, the ALTER ADAPTER command takes effect
immediately. You should issue only one ALTER ADAPTER command. This change
causes the SWAN CLIP to restart. If two ALTER ADAPTER commands are issued,
then you will be restarting the CLIPs again.
