Chassis Cluster
|
|
Redundant Ether-interface Count
|
Specifies the number of redundant Ethernet Interfaces to be
created for the cluster.
|
Specify a value between 1 and 128.
|
|
Heartbeat Interval
|
Specifies, in milliseconds, how often heartbeats are sent out
to the other nodes in the cluster.
The default heartbeat interval is 1000.
|
Specify a value between 1000 and 1200.
|
|
Heartbeat Threshold
|
Specifies the number of consecutive missed heartbeats that indicate
a cluster failure.
The default number is 3.
|
Specify a value between 3 and 8.
|
|
Nodes
|
Specifies the nodes to be used for the chassis cluster.
|
To specify a node, select the node from the list and click Add.
To delete a node, select the node you want to delete and click Delete.
|
|
Group Number
|
Displays the selected redundancy group information or creates
or modifies a redundancy group.
|
Select a group number from the list of configured redundancy
groups.
- To modify information for a redundancy group, select the
corresponding group number. Specify a value between 1 and 255.
- To create a new redundancy group:
- Assign a group ID to the redundancy group. Specify a value
between 1 and 255.
- Configure the redundancy group with information described
in the rest of this table.
|
|
Gratuitous ARP Count
|
For a redundancy group, specifies the number of gratuitous Address
Resolution Protocol (ARP) requests that a newly elected master sends
out on the active redundant Ethernet interface child links to notify
network devices of a change in mastership on the redundant Ethernet
interface links.
The default value is 4.
|
Specify a value between 1 and 16.
|
|
Preempt
|
For a redundancy group, allows a node with a better priority
to initiate a failover. By default, this feature is disabled. When
disabled, a node with a better priority does not initiate a redundancy
group failover (unless some other factor, such as faulty network connectivity
identified for monitored interfaces causes a failover).
|
Select the check box.
|
|
Priorities
|
For a redundancy group, specifies the priority value of each
node. The redundancy group becomes primary on the node with the best
(higher) priority.
By default, this feature is disabled.
|
Select a node and a priority number, then click Add. The value is a number between 1 and 225.
|
|
Interface-Monitor
|
For a redundancy group, specifies the interfaces to be monitored
by the redundancy group and their respective weights.
|
Select the interface from the list and enter its weight. The
value is a number between 1 and 255.
