NAME

       in the following sections.

	      [1 | 2 | 3 | 4] {
		options:
		  address [IP address | none]
		  [disabled | enabled]
		  priming [disabled | enabled]
	      }
	    }
	    min-up-members [integer]
	    min-up-members-enabled [no | yes]

	    all-properties
	    non-default-properties

   DISPLAY
	list cluster
	  options:
	    all-properties
	    non-default-properties
	    one-line

	show running-config cluster
	show running-config cluster [option name]

	show cluster [option name]
	  options:
	    all-properties
	    field-fmt

DESCRIPTION
       You can use the cluster component to modify the configuration of the
       primary blade in a cluster. When you do this, the system automatically
       propagates the changes to the other blades in the cluster. This is
       known as cluster synchronization.

EXAMPLES
       modify cluster default address 192.168.217.44/24

       Sets the floating management IP address for the cluster default to an
       IP address of 192.168.217.44.

       list cluster my_cluster

       Displays the properties of the cluster named my_cluster.

OPTIONS
	    address

	    Specifies an IP address for the cluster or cluster member. The
	    default value is none.

	    disabled

	    Disables the specified cluster member. The default value is
	    enabled.

	    enabled

	    Enables the specified cluster member. This is the default value.

	    members

	    Specifies the cluster members to be acted on by the command. A
	    cluster member is a slot into which you insert a blade. The
	    cluster member is identified by the number assigned to the slot.

	    min-up-members

	    Specifies the minimum number of cluster members that must be up
	    for the cluster to remain Active. The default value is 0.

	    min-up-members-enabled

	    When set to yes, specifies that when the number of cluster members
	    that are active is below the value of the option min-upmembers,
	    the cluster fails over to its peer. The default value is no.

	    Enable this parameter when you configure a redundant pair.

	    Important: Make sure that you modify the value of the min-up-
	    members option appropriately when you take blades down in a
	    cluster. Otherwise, you can get into the condition where disabling
	    a cluster member brings the cluster below the value of the option
	    min-up-members, which can cause the cluster to fail over to its
	    peer.

	    name

	    Specifies a name for the cluster. This option is required.

	    priming

	    Prevents a cluster member from proceeding to the RUNNING cluster
	    quorum state, which is useful when a blade is in a reboot loop.
	    The default value is disabled.
