Verifying a WAN Subsystem Device Configuration
2. Each device has requirements imposed on its configuration by the data
communications subsystem to which it belongs.
Check the device-specific modifiers for the device by using the SCF INFO DEVICE
command with the DETAIL option:
INFO DEVICE $ZZWAN.#<device-name>, DETAIL
Displaying Modifiers for a WAN Subsystem Device on page A-5 shows the output
of this command.
3. If the device is a line-handler process, check the current modifiers used by the
communications line by using the SCF INFO LINE command using the DETAIL
option. Checking current modifiers might be necessary because changes made
with the subsystem-specific SCF ALTER command are not displayed by the SCF
INFO DEVICE command.
For example, to check the current Layer 4 attribute settings for an Expand line, use
the SCF INFO LINE command with the DETAIL option:
INFO LINE $LINE1, DETAIL
4. Make sure that subsystem-specific objects (such as SU objects for X25AM lines)
are configured correctly.
For information about fixing a WAN subsystem device configuration error, see
Changing a WAN Subsystem Device Configuration.
Note. You must read the Configuration and Management Manual for the data
communications subsystem for product-specific requirements.
Note. Changes made through the WAN subsystem's SCF ALTER DEVICE command are
permanent (they persist through system and processor reloads). Changes made through
the subsystem-specific SCF ALTER LINE commands are temporary (they do not persist
through system and processor reloads).
Note. For the appropriate communications subsystem information about valid modifiers,
see the Configuration and Management Manual. For information about configuring
subsystem-specific objects, see Table 2-1
on page 2-12.
