Add

To add a HA cluster interface:

  1. Click + at the upper right side of the Interfaces table.

    The Add HA Cluster Interface window appears.

  2. Enter the following details for Fabric Link:

    Fabric Link 0 (fab0)

    • Interface—Enter the interface IP address for fabric link 0 and click + to add it.

    • Select an existing interface and click X to delete the interface.

    Fabric Link 1 (fab1)

    • Interface—Enter the interface IP address for fabric link 1 and click + to add it.

    • Select an existing interface and click X to delete the interface.

  3. Enter the following details for Redundant Ethernet:
    • Interface—Enter the logical interface. This specifies a logical interface consisting of two physical Ethernet interfaces, one on each chassis.

    • IP—Enter redundant Ethernet IP address.

    • Redundancy Group—Select one of the redundancy group from the list. Else, enter a redundancy group.

    • lacp—Select an option from list:

      • active—Initiate transmission of LACP packets.

      • passive—Respond to LACP packets.

    • periodic—Select an option from list for periodic transmission of LACP packets. The options are fast or slow.

    • Click + to add the redundant Ethernet configuration.

    • Select one or more existing redundant Ethernet configurations and click X to delete it.

  4. Click OK to save the changes. If you want to discard your changes, click Cancel.

Edit

Select an interface and click the pencil icon at the upper right side of the Interfaces table.

The Edit HA Cluster Interface window appears with editable fields. Once you complete the your edits, click OK to save the changes.

Delete

Select the existing interfaces and click the delete icon at the upper right side of the Interfaces table.

Click OK to delete.

Redundancy Group

Group

Displays the redundancy group identification number.

Preempt

Displays the selected Preempt option.

  • True–Primary Role can be preempted based on priority.

  • False–Primary Role cannot be preempt based on priority.

Gratuitous ARP Count

Displays the number of gratuitous ARP requests that a newly elected primary device in a chassis cluster sends out to announce its presence to the other network devices.

Node Priority

Displays the assigned priority for the redundancy group on that node. The eligible node with the highest priority is elected as primary for the redundant group.

Add

To add a redundancy group:

  1. Click + at the upper right side of the Redundancy Group table.

    The Add Redundancy Group window appears.

  2. Enter the following details for Fabric Link:
    • 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 ranges is from 1 through 125.

      • Click + to add the interface monitor configuration.

      • Select one or more existing interfaces and click X to delete them.

    • IP Monitoring:

      • Weight—Enter a value to specify the weight for IP monitoring. The ranges is 0 through 225.

      • Threshold—Enter a value to specify the global threshold for IP monitoring. The ranges is 0 through 225.

      • 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.

    • IPv4 Addresses to be monitored:

      • IP—Enter an IPv4 address to be monitored for reachability.

        You select an existing IP address and can click X to delete it.

      • Weight—Enter a value to specify the weight for the redundancy group interface to be monitored.

      • Interface—Enter a value to specify the logical interface to monitor this IP address.

      • Secondary IP address—Enter the secondary IP address for monitoring packets on a secondary link.

      • Click + to add the IPv4 Addresses to be monitored configuration.

  3. Click OK to save the changes. If you want to discard your changes, click Cancel.

Edit

Select a group and click the pencil icon at the upper right side of the Redundancy Group table.
