Figure 1-54 LNMC external interactions
As shown in Figure 1-54, the following external interactions are featured in the LNMC:
1. Network configuration commands
The primary function of this procedure is to uniquely identify the Power 775 server within
the network. This includes the following information:
– Network topology
– Supernode identification
– Drawer identification within the Supernode
– Frame identification (from BPA via FSP)
– Cage identification (from BPA via FSP)
– Expected neighbors table for mis-wire detection
2. Local network hardware events
All network hardware events flow from the ISR into the LNMCs event management, where
they are examined and acted upon. The following list of potential actions that are taken by
event management:
– Threshold checking
– Actions upon hardware
– Event aggregation
– Network status update. Involves route management and CNM reporting.
– Reporting to EMS
