Configuring SNA
9-11
Maxdata
must correspond to the PIU size configured on the host (parameter MAXDATA of
macro PU in VTAM). For a link between a PU type 4 and a PU type 2, the frame size
configured for the TPAD port must be set at the value of MAXDATA in VTAM plus
6 bytes (corresponding to the length of the link header and the link trailer).
Autocall
causes automatic calling between SNA ports when the controller (identified by Link
Address) becomes active. If set to
Y
on an SNA port, an X.25 call will be made from
the local port to the remote subscriber port.
Autocall Retry Time
is the time between autocall retries.
Autocall Retry Count
is the maximum number of times an autocall will be sent. Note that a value of
0
allows
indefinite retries.
Istatus
affects the line and PU the same way
Blocked Port Flag
affects the port. If configured
as
Inactive
, the PU will be disabled until either an on-line enable is performed (see
) is sent from a NetView manager device.
LPDA Resource ID
identifies a logical unit (LU) on the PU. LPDA requires both a PU name and an LU
ID. The Resource ID value must match the NetView LOCADDR.
LLC2 Connection
specifies whether SDLC-LLC2 conversion will be done on the PU connection, either
locally or at a remote node via an X.25 logical or physical port.
If SDLC-LLC2 conversion will be done, LLC2 Connection must
be configured as
Y
; otherwise, the PU will not re-activate
properly after the session unless an on-line update (
[F7]
) is per-
formed in the logical port record.
L2DatMode
determines whether transmission can be in one (alternate) or two (simultaneous) direc-
tions at the same time.
LLC2 Parameters
Local SAP Address
is the remote service access point (SAP) address used to connect the PU to the host.
This parameter is relevant only in a connection to a 3174 or AS/400-type setup where
a specific source SAP address is required. If the LLC2 session will be run over a native
LLC2 frame relay interface, the parameter will be ignored.
Local MAC Address
identifies the PU to the host. Like the local SAP address, this parameter is relevant
only in a connection to a 3174 or AS/400-type setup where a specific source MAC
address is required. If the LLC2 session will be run over a native LLC2 frame relay
interface, the parameter will be ignored.
