ACF/NCP and ACF/VTAM Macro and Operands Descriptions | |
This section describes the ACF/NCP and ACF/VTAM operands for the LUDRPOOL, GROUP, LINE, SERVICE, VBUILD, PU, and LU macros. This section contains generic descriptions of the macros and operands. Refer to the tables earlier in this chapter for operand values that are specific to the configuration of the HP SNA products. See the NCP or VTAM manual for the remote system for a more thorough explanation of the parameters and their values. The GROUP macro can contain all of the operands of the LINE, PU, and LU macros that are allowed to be defined at a higher level. This results in a "shift-down" effect of these operands to the LINE, PU, and LU macros defined below it. The operands could have also been defined on the lowest level macro allowed. The resulting VTAM/NCP configuration is identical using either method. The placement of operands in higher level macros saves time and space when trying to determine which operands affect which macros. This macro defines a pool of LU control blocks for switched lines. - NUMTYP2
Specifies the number of LUs to be included in the LU pool for type 2 PUs.
This macro specifies certain common characteristics and functions for a group of links and devices. - DIAL

If no response is received from the station by the time specified, a time-out error is indicated and NCP makes no further attempt to communicate. NCP parameter Default: 1.0 Range: 0-1632 | | | |  | NOTE: Network delays must be considered when specifying REPLYTO. | | | | |

Specifies the maximum frame size (in bytes)
allowed in one data transfer on the link. For a type 2.0 and type
2.1 node, this includes 3 bytes for the RH, and 6 bytes for the TH.
This value depends on the network card installed on the HP system. For

to the remote PU. For type 2.1 node operation,
XID must be set to YES. NCP
parameter Range: YES, NO
There must be an LU definition for each LU associated with a PU. An
LU macro must be coded for each IBM 3270 emulation device attached
to an IBM 3270 service. For example, emulation of an IBM 3274
cluster controller with three IBM 3278 keyboard/displays and one IBM
3286 printer requires four separate LU macro statements. - lunameLU
A symbolic name for this LU. The name consists of
one to eight characters and must be unique throughout the network.
luname is used by
application subsystems, such as CICS, to specify a particular LU. - LOCADDR

NETTYPE=3. When X.25 NPSI
receives a RESET 07, it continues sending physical services commands

X25.OUFT statement within this NPSI generation.

virtual circuits associated with this VCCPT entry. When this keyword
is coded, two percentages must be supplied, separated by a
comma.

unsafe percentage
Percentage 2--the
danger percentage
|
These values are not absolute; they are defined
in relation to the value of the NCP SLODOWN

means that the unsafe buffer use level is 12 percent higher than the
value of SLODOWN and the danger buffer use
level is 6 percent higher than the value of
SLODOWN. The unsafe percentage must be greater than the
danger percentage.
Default:
(50,12)

IBM requires that the value specified for
FRMLGTH equal the MAXPKL (see
X25.VCCPT macro) size plus 3 bytes for the modulo 8 X.25 packet
header. (HP supports modulo 8 only). IBM's
FRMLGTH does not equal the X.25 N1 parameter divided by
8.
Note that this value will not be the same as the Frame
Size value in the HP DTC configuration. HP DTC
configuration interprets Frame Size to equal
the value of the X.25 N1 parameter divided by 8, which is the sum of
the data packet size plus 3 bytes for the packet header and 4 bytes
for the LAP-B header and LAP-B trailer.
HP's Frame Size value

circuit.

0). - TYPE
Specifies whether this X25.VC statement defines
a switched virtual circuit (SVC) or a permanent virtual circuit

Specifies the IBM X.25 Network Address.
IBM X.25 net addr
may be 15 characters long. HP requires that the IBM X.25 Network
Address be included in the DIALNO definition
because the X.25 Call Packet header is checked for the IBM address
when a call is received at the HP system. If the address is not
included in the packet header (because it was omitted in the
DIALNO definition) or if the address does not agree with
the remote address configured in the HP configuration, the call will
be rejected.

cluster controller with three IBM 3278 keyboard/displays and one IBM
3286 printer requires four separate LU macro statements. - luname LU

This is a hexadecimal value, in the format 'abcd', where '2b * a' equals the inbound to host RU size in bytes, and '2d * c' equals the outbound from host RU size, in bytes. Possible values are shown in table 1-25. To use the table, locate the desired RU size in table 1-25. The values of the Ax columns and Bx rows determine the first and second hexadecimal values for the RU size. For example, an
inbound RU size of 256 has Ax and Bx values of '8' and '5', respectively, or a hexadecimal value of '85'. Therefore, an inbound/outbound RU size of 256 is '8585'. - SECPROT
