Changing a WAN Subsystem Device Configuration
Changing a WAN Subsystem Device
Configuration
If a WAN subsystem device (DEVICE object) is configured incorrectly or a WAN
subsystem device requires configuration:
1. Stop the communications line (if the device is a line-handler process) and then stop
the device. For specific instructions and SCF commands for your communications
subsystem, see the appropriate manual (see Table 2-1 on page 2-12).
2. Modify the device using the SCF ALTER DEVICE command:
ALTER DEVICE $ZZWAN.#device-name
[ , ADAPTER adapter ]
[ , CLIP clip-num ]
[ , HIGHPIN setting ]
[ , IOPOBJECT object-file ]
[ , LINE line-num ]
[ , PATH path ]
[ , RECSIZE | RSIZE max-rec-size ]
[ , RESET modifier ]
[ , TYPE (type,subtype) ]
[ , modifier-keyword modifier-value ]
The attributes for the SCF ALTER DEVICE command are the same as the
attributes for the SCF ADD DEVICE command. For more information about the
SCF ADD DEVICE command, see the WAN Subsystem Configuration and
Management Manual.
You can also use the SCF ALTER command provided for a specific
communications subsystem (such as Expand) to make configuration changes.
Keep in mind that changes made using the subsystem-specific SCF ALTER
command are temporary (they do not remain across system loads) while changes
made using the WAN subsystem's SCF ALTER DEVICE command are permanent
and remain across system loads.
3. Restart the device and the communications line (if applicable). See the appropriate
communications subsystems manual for specific instructions.
