Enhanced XPM node table synchronization
Data
Active unit
Feature AF5678 adds a new software component, configuration data table
(CDT) management. The CDT bind interface allows XPM applications to
bind an aspect with the set of procedures of the CDT bind interface. This
event occurs during initial program load (IPL). An XPM with a software
load bound with the new CDT management system notifies the CM during
an XPM node data audit. The CM starts a CDT audit every 5 min. This
action starts the XPM node data audit in the XPMs.
The CDT/XPM node audit converts XPMs with compatible software loads
to the new node table management control. The CDT/XPM node audit
checks the sanity of converted XPMs. To maintain backward compatibility,
XPMs with software loads without CDT management capability continue to
maintain mate unit synchronization. The XPMs with software loads without
CDT management capability continue to maintain mate unit
synchronization.
The CM controls both units of an XPM node when conditions occur as
follows:
Configuration table map
Node and
information does not
port tables
transmit to the inactive unit
The CDT/XPM node data audits update the tuple(s) of that node in table
PMNODES. The updated tuple(s) and the data and indexes sequence of
the tuples in the XPM node and port tables match.
The CM had control of both units in a previous software load.
