Status Request Function
The LBS Status Request Function accepts and responds to requests for status from
the IBM LAN Network Manager application.
Set Parameters Function
The LBS Set Parameters Function accepts and executes commands from a
controlling IBM LAN Network Manager. The commands change the operational
parameters of LBS.
Notification Function
The LBS Notification Function collects inter-ring traffic statistics and forwards
this information to the IBM LAN Network Manager application. This function
also notifies IBM LAN Network Manager of LBS state changes.
Bridge Performance Monitoring Function
The LBS Bridge Performance Monitoring Function maintains counters for
• The number of frames and bytes forwarded through the bridge
• The number of frames not received by a bridge station because the station was
congested
Periodically the percentage of frames lost or discarded by the bridge because of
anomalies is calculated and, if the percentage exceeds a predefined threshold, LBS
sends a notification to the IBM LAN Network Manager application.
LBS can also be configured to periodically send its error and traffic counters to the
IBM LAN Network Manager application to allow for trend analysis by the
application.
