NOF Indications
LOCAL_TOPOLOGY_INDICATION
Number of normal flow data frames received.
lu_sscp_stats.rcv_fmd_data_frames
Number of normal flow function management data (FMD) frames received.
lu_sscp_stats.rcv_data_bytes
Number of normal flow data bytes received.
lu_sscp_stats.sidh
Session ID high byte.
lu_sscp_stats.sidl
Session ID low byte.
lu_sscp_stats.odai
Origin Destination Assignor indicator. When activating a session, the sender of the ACTLU sets this parameter
to zero if the local node contains the primary link station and sets it to one if the ACTLU sender is the node
containing the secondary link station.
lu_sscp_stats.ls_name
Link station name associated with statistics. This is an 8-byte string in a locally displayable character set.
All eight bytes are significant. The parameter can be used to correlate this session with the link over which
the session flows.
lu_sscp_stats.pacing_type
Receive pacing type in use on the LU-SSCP session. This will take the value
AP_NONE.
sscp_id
The identifier of the SSCP as received in the ACTPU for the PU used by this LU. This parameter is 6
bytes and is used only by dependent LUs. This parameter is set to all zeros for independent LUs or if the
lu_sscp_sess_active parameter is not set to
AP_YES.
4.12 LOCAL_TOPOLOGY_INDICATION
This indication is generated when one of the following occurs:
• A TG in the local node’s topology database changes state between active and inactive.
• A TG in the local node’s topology database changes state between quiescing and not quiescing.
• A contention winner CP-CP session over a TG in the local node’s topology database is activated or deactivated.
