Redundancy Group

Enter the redundancy group name.

Allow preemption of primaryship

Select the check box to allow a node with a better priority to initiate a failover for a redundancy group.

Note:

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).

Gratuitous ARP Count

Enter a value. The range is 1 through 16. The default is 4.

This specifies the number of gratuitous Address Resolution Protocol requests that a newly elected primary sends out on the active redundant Ethernet interface child links to notify network devices of a change in primary role on the redundant Ethernet interface links.

node0 priority

Enter the node priority number as 0 for a redundancy group.

node1 priority

Enter the node priority number as 1 for a redundancy group.
Interface Monitor

Interface

Select an interface from the list.

Weight

Enter a value to specify the weight for the interface to be monitored. The range is from 1 through 125.

Retry Count

Enter a value to specify the number of retries needed to declare reachability failure. The range is 5 through 15.

Retry Interval

Enter a value to specify the time interval in seconds between retries. The range is 1 through 30.
