ZFSM–DT
reports the SNAX/HLS implementation of FSM_DT. This field records the value
of the data traffic finite state machine. This FSM indicates whether the session can
transfer application data. The condition of this FSM controls the summary state
reported for bound sessions. When the FSM has the value
ZHLS–VAL–FSM–DT–ACTV, the session is in the STARTED summary state. When
the FSM has the value ZHLS–VAL–FSM–DT–RESET, the session is in the
SUSPENDED summary state. Any other value is reported as the STARTING
summary state.
This field can have the following enumerated values:
ZHLS–VAL–FSM–DT–ACTV
indicates that the session can carry normal FMD and DFC traffic. This
condition will persist until either the session is terminated or the data traffic
condition is reset by using the CLEAR request.
ZHLS–VAL–FSM–DT–NULL
indicates that this FSM is not yet initialized or is not used in the current
session.
ZHLS–VAL–FSM–DT–P–ACTV
indicates that the SDT request has been sent (or received), but the SDT
response has not been received (or sent).
ZHLS–VAL–FSM–DT–P–RESET
indicates that the CLEAR request has been sent (or received), but the CLEAR
response has not been received (or sent).
ZHLS–VAL–FSM–DT–RESET
indicates that the session cannot transmit data. In SNA terms, this means no
FMD or DFC traffic can flow. This situation arises immediately after the BIND
record has been sent (or received). For FM profiles other than 2, it indicates
that the set and test sequence number (STSN) and SDT records are yet to be
exchanged. (For FM–profile 2, this situation cannot arise because the STSN
and SDT records are not used.)
ZFSM–SESS
reports the SNAX/HLS implementation of FSM_SESS. This finite state machine
controls the session–establishment protocol.
This field has the following enumerated values:
