Configuring Expand-Over-X.25 Lines

Considerations
Default values and ranges of values for modifiers in the PEXQSNAM profile are
described in Profile Modifiers on page 10-13.
Considerations
•
Not all modifiers have associated values (for example, L4EXTPACKETS_ON).
•
The modifier_keyword and modifier_value parameters do not add the
specified modifier, or a modifier and its associated value, to the profile used by the
device. Use the ADD PROFILE command to add a modifier, or a modifier and its
associated value, to a profile.
Examples
In the following example, a device named $EXPSL3 is created for a single-line
Expand-over-X.25 line-handler process. $EXPSL3 will bind to a NAM subdevice
named #XNAM on the X25AM line-handler process named $X2501. The L4TIMEOUT
modifier is recommended for Expand-over-X.25 line-handler processes.
-> ADD DEVICE $ZZWAN.#EXPS13, PROFILE SLHX25, IOPOBJECT &
$SYSTEM.SYSTEM.LHOBJ, CPU 0, ALTCPU 1, TYPE (63,0), &
RSIZE 0, PATHTF 3, NEXTSYS 31, ASSOCIATEDEV $X2501, &
ASSOCIATESUBDEV #XNAM, 14TIMEOUT 3000
In the next example, the same device is created as part of a multi-CPU path. The
SUPERPATH_ON and L4EXTPACKETS_ON modifiers are required for line-handler
processes that are part of a multi-CPU path. The L4CONGCTRL_ON modifier is
recommended for Expand line-handler processes that are part of a multi-CPU path.
-> ADD DEVICE $ZZWAN.#EXPS13, PROFILE SLHX25, IOPOBJECT &
$SYSTEM.SYSTEM.LHOBJ, CPU 0, ALTCPU 1, TYPE (63,0), &
RSIZE 0, PATHTF 3, NEXTSYS 31, ASSOCIATEDEV $X2501, &
ASSOCIATESUBDEV #XNAM, 14TIMEOUT 3000, 14EXTPACKETS_ON, &
14CONGCTRL_ON, SUPERPATH_ON
Step 5: Start the Expand-Over-X.25
Line-Handler Process
To start a single-line Expand-over-X.25 line-handler process, use the WAN subsystem
SCF START DEVICE command. The command syntax is as follows:
$ZZWAN.device_name
specifies, via the WAN subsystem, the device name of the Expand-over-X.25
line-handler process.
This command creates the specified Expand line-handler process and allocates a
logical device (LDEV) number.
START DEVICE $ZZWAN.#device_name
