Edit Cluster Parameters
                When editing a cluster node, you can only edit the cluster master preference. You can only change the cluster master preference on one node at a time.
                For the master preference, higher values are more likely to claim the Master and Standby roles; lower values are less likely.
                To edit master preferences:

                        To set the master preference for devices, right-click the required device and click the Edit Details options button.  |

                         | 
                        The Device configuration quick view should appear on the right. Edit the Master Preference in the text box. | 
                    
                
                
                Note:  Most of the fields are read-only. You can change the cluster master preference, as desired. Use preference settings from 10 to 100 for master, standby, and normal roles. Use preference settings from 1 to 9 for normal nodes that are excluded from taking the master or standby role. GigaVUE TA Series nodes always have a preference of 1.

                A Confirmation window appears advising that all traffic configurations will be erased on newly added or removed nodes.

                        The Manage Cluster update notification window appears showing the status of each update activity on the nodes, cards, GigaStreams and stack links.  |

                        After the cluster update operation completes, a “Manage Cluster Completed” message appears. |
