show sna cp services transmission group
The show sna cp services transmission group command displays the
values of the attributes for the SNA CP Services Transmission Group
entity. The SNA CP Services Transmission Group subentity represents
a link between a Peer Server local link station and an adjacent SNA
system link station. The connection type can be permanent in which
the data link connection remains active when unused, or temporary in
which the connection is automatically terminated when unused.
Ex, ncl> show sna cp services transmission group tg-1 -
_ncl> connection type, node id
1 – Identifier
Name The unique Simplename of the Transmission Group
entity that is maintained by the Peer Server.
2 – Status
UID Displays the unique identifier that the
Peer Server associates with the
Transmission Group.
State Displays the operational state of
the Transmission Group subentity.
Setting the state is a result of
execution of the enable/disable
commands. The states are
Off The Transmission Group is disabled
and not available for use.
On The Transmission Group is enabled
and available for use.
Shut The Transmission Group is waiting
for the end of active sessions, if any.
Protocol Displays the protocol state of the
State Transmission Group. These states are
Connected The Transmission Group is active.
The Transmission Group enters this
state from the connecting state after
successful XID exchange.
Connected The link station is active and the
Pending Transmission Group connection type
Disconnect is temporary. A transition to zero
sessions has started the disconnect timer.
Connected - The link station is active and capable
PU Active of supporting dependent LUs. The
Transmission Group enters this state
from the connected state when an
ACTPU is successfully processed.
Connecting An enabled Transmission Group is
being activated locally by a session
initiation request from a non-SNA
network or remotely when a link
station is activated from an adjacent
node.
Disconnecting The link station is in the process of
deactivating. This is for permanent
Transmission Groups. The entity state
remains on.
Disconnect For temporary Transmission Groups, the
Reset link station is in the process of de-
activating. The entity state is off.
Idle The link station is available but
inactive. This state is entered when
the Transmission Group is enabled. A
temporary Transmission Group is
activated locally by a session
initiation request from a non-SNA network
or remotely when a link station is
activated from an adjacent node.
Reset Resets the link station. This is the
creation state.
INIT_SELF Displays whether the adjacent link
Supported station supports receipt of INIT_SELF.
This attribute is relevant only if the
Transmission Group is active.
BIND Displays, if the Transmission Group is
Supported active, whether the Peer Server can
send Rq (BIND) RUs to the adjacent
link station.
Adjacent Node Displays whether the adjacent node
BIND Assembly can assemble BIND segments.
BIND Pacing Displays, if the Transmission Group is
Support active, the type of BIND pacing that
the Transmission Group supports.
Dependent LU Displays, if the Transmission Group is
BIND Pacing active, whether BIND pacing applies
to dependent LUs.
SSCP Displays whether the adjacent node
Mediated requires ACTPU.
Sessions
Adjacent Displays the node id of the adjacent
Station node. This value is supplied during
Node ID connection.
Adjacent Displays the network id of the
Network ID adjacent node.
Adjacent Displays the non-network qualified
Station name of the CP of the adjacent link
CP Name station.
Adjacent Displays the network name of the PU
Station at the adjacent link station. This
PU Name attribute is either blank or it contains
the non network qualified PU name of
the adjacent link station.
Adjacent Displays the local name of the Adjacent
Station ALS Link Station at the XID sender.
Name
3 – Characteristics
Intranode yes | no Displays whether this Transmission
Group is an Intranode Transmission
Group. The default is no. If you
specify yes, note the characteristics
that do to apply.
Connection permanent | Permanent means that the Transmission
Type temporary Group is activated when it is enabled
and remains active until it is
disabled. Temporary means that the
Transmission Group is activated when
a local session is created or a rem-
ote link station is activated, and
deactivated when there are no
sessions. The default is permanent.
Dependent yes | no Displays whether Dependent LUs
LU Support exist for the Transmission Group.
This attribute controls the
acceptance of ACTPU, DACTPU, ACTLU,
and DACTLU RUs as well as the LFSID
address space assignments for the
Transmission Group. The default is
No. Characteristic does not apply if
Intranode is yes.
Segmentation session | Displays the kind of segmentation to
Support station | be performed by the Peer Server when
none communicating with the adjacent link
station. The default is session.
Characteristic does not apply if
Intranode is yes.
BIND Pacing (1-32767) Displays the amount that the adaptive
Window BIND pacing algorithm increases the
Increment receive window size when a larger
window size is requested by the BIND
sender and when there are adequate
resources. This parameter is valid
when receive BIND pacing is in
effect for the Transmission Group.
The default is 1. Characteristic does
not apply if Intranode is yes.
Disconnect (0-3600) Displays the amount of time (in
Timer seconds) a temporary Transmission
Group should delay after zero
sessions are active before
deactivating the link station.
The default is 30.
XID Retry (1-60) Displays the interval (in seconds)
Timer specified for XID send expiration
(retry). The default is 3.
Characteristic does not apply if
Intranode is yes.
Data Link Simplename Specifies the local entity name for
data link and instance used by the
Transmission Group (TG). In the ex-
ample, qllc link qllc-0 station ncp,
ncp is the name of the local entity
used by the TG.
Node ID 1- to 8-hexa- Displays the node identifier value
decimal char- for the Peer Server. This value is
acters (pre- used in XID exchange if the value is
ceded by %x) specified. The default is hexadecimal
00000000. Characteristic does not
apply if Intranode is yes.
Required 1- to 8-hexa- Displays the node identifier value of
Adjacent decimal char- the adjacent node. If specified, this
Node ID acters (pre- value must match that of the adjacent
ceded by %x) node. Characteristic does not apply
if Intranode is yes.
Required Simplename Displays the network id of the
Adjacent adjacent node. If specified, this
Network ID value must match the network ID
supplied by the adjacent node at
connect time or the connection will
fail. The value must be a valid SNA
network name. Characteristic does not
apply if Intranode is yes.
Required Simplename Displays the CP Name of the adjacent
Adjacent node. If specified, the CP Name must
CP Name match the name supplied by the
adjacent link station at connect time
or the connection will fail. The
value must be a valid SNA network
name. Characteristic does not apply
if Intranode is yes.
