Configuring SNA 8-9
PU Subscriber Parameters
PU Name
identifies the PU to an SNMP or NetView host.
Local Subscriber ID
is the subscriber address of the local end of an SNA connection. (A Subscriber ID—
see page 8-13—must also be configured.)
Remote Subscriber ID
is the subscriber address of the remote end of an SNA connection. (A Subscriber ID—
see page 8-13—must also be configured.)
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.
If both ends of a connection are configured for autocall, their retry timers (see next
entry) should be different, to avoid collisions.
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.
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.
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
page 16-16) or a VARY ACT (see page E-4) is sent from a NetView manager device.
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.
