secondary cluster protocol network) for this length of time, it leaves the
cluster and attempts to rejoin it. You might need to adjust this value if
congestion on the primary or secondary network causes nodes to repeatedly
leave and rejoin the cluster (though the cluster protocol attempts to prevent
this situation by sending data at shorter intervals if it detects delays).
To change the number of milliseconds the node waits before assuming cluster
breakup, enter a number in the F

Configuring the Performance Rating
The performance rating is a measure of a cluster member's throughput and
performance capabilities. The higher the rating, the more work a cluster
member is capable of doing.
In forwarding mode, cluster members use the performance rating to elect the
best performing system as the master. The cluster master receives all the
packets for the cluster first, so the performance of the master affects the
performance of the whole cluster. If a joining system has a higher rating than
the other nodes, it becomes the master. If more than one system have the same
performance rating, the first system to join the cluster is the master.
In forwarding and multicast mode, the cluster master takes the performance
rating of the members into account when assigning workload. Nodes with
higher performance ratings receive a larger share of the workload than lower
performing nodes.
The default performance rating for a system reflects its performance relative
to that of other Nokia platforms. You can adjust the performance rating to
change the amount of work a system is assigned relative to other members. If
a cluster uses forwarding mode, you can adjust the performance rating to
force a particular node to be the master (which will also have the effect of
giving that node a larger share of work).
To change the performance rating, enter a number in the P
