Configuring Layer 4 Attributes
•
After adding X.25 PROFILE objects, you associate them with particular SNPA
addresses using SNPA ENTRY objects. See Adding SNPA ENTRY Objects on
page 4-26.
Configuring Layer 4 Attributes
Configure Layer 4 service characteristics for TSP processes by using either the Layer 4
SERVICE object or the Layer 4 PROFILE object. (To configure these objects, you
should understand the meaning of Transport Layer protocol values.)
•
Use the Layer 4 SERVICE object to set default transport service characteristics.
•
Use the Layer 4 PROFILE object to set service characteristics for transport
subdevices using specific NSAP addresses.
See Section 2, Management Environment
, for more information on the use of the
SERVICE and PROFILE objects.
Example 1: ALTER SERVICE
The following command configures all the TSP processes in the subsystem to
implement the transport class 3 protocol and to enable multiplexing:
ALTER SERVICE $OSIM.#L4, CLASS 3, MULTIPLEX ON
The command and object-spec identify the Transport Layer of the subsystem controlled
by the OSI manager process $OSIM:
ALTER SERVICE $OSIM.#L4
The two attribute-specs implement the transport class 3 protocol and enable
multiplexing:
CLASS 3, MULTIPLEX ON
This means that all connections using the SERVICE #L4 attributes as defaults use
transport class 3 protocol and allow multiplexing.
Example 2: ADD PROFILE
The following example adds a Transport Layer PROFILE object:
ADD PROFILE $OSIM.#L4.TPFILE1, CLASS 4, REXMITTIMEOUT 20
When the OSI manager process registers this profile in the MIB, it includes in the
profile definition all other service attributes not specifically defined in the ADD
PROFILE command.
The command and object-spec add the Layer 4 PROFILE object TPFILE1 to the OSI
manager process $OSIM:
ADD PROFILE $OSIM.#L4.TPFILE1
The first attribute-spec assigns transport protocol class 4 to the PROFILE object:
CLASS 4
