The following operations can be performed on “cluster-node”:
| stat | rm | add | bind | unset | set | show | unbind |
stat cluster node
Displays statistics for a cluster node.
Synopsis
stat cluster node [
Arguments
nodeId ID of the cluster node for which to display statistics. If an ID is not provided, statistics are shown for all nodes. Minimum value: 0 Maximum value: 31
detail Specifies detailed output (including more statistics). The output can be quite voluminous. Without this argument, the output will show only a summary.
fullValues Specifies that numbers and strings should be displayed in their full form. Without this option, long strings are shortened and large numbers are abbreviated
ntimes The number of times, in intervals of seven seconds, the statistics should be displayed. Default value: 1 Minimum value: 0
logFile The name of the log file to be used as input.
clearstats Clear the statsistics / counters
Possible values: basic, full
Output
count devno stateflag

Related Commands
rm cluster node
Removes a node from the cluster and removes the cluster instance from the node. You must execute this command on the cluster IP address.
Synopsis
rm cluster node
Arguments
nodeId ID of the cluster node to be removed from the cluster. Minimum value: 0 Maximum value: 31
clearNodegroupConfig Option to remove nodegroup config
Possible values: YES, NO Default value: YES
force Node will be removed from cluster without prompting for user confirmation.
Example
rm cluster node 1
add cluster node
Adds a Citrix ADC to a cluster.
Synopsis
add cluster node
Arguments
nodeId Unique number that identifies the cluster node. Minimum value: 0 Maximum value: 31
IPAddress Citrix ADC IP (NSIP) address of the appliance to add to the cluster. Must be an IPv4 address.
state Admin state of the cluster node. The available settings function as follows: ACTIVE - The node serves traffic. SPARE - The node does not serve traffic unless an ACTIVE node goes down. PASSIVE - The node does not serve traffic, unless you change its state. PASSIVE state is useful during temporary maintenance activities in which you want the node to take part in the consensus protocol but not to serve traffic.
Possible values: ACTIVE, SPARE, PASSIVE Default value: PASSIVE
backplane Interface through which the node communicates with the other nodes in the cluster. Must be specified in the three-tuple form n/c/u, where n represents the node ID and c/u refers to the interface on the appliance. Minimum value: 1
priority Preference for selecting a node as the configuration coordinator. The node with the lowest priority value is selected as the configuration coordinator. When the current configuration coordinator goes down, the node with the next lowest priority is made the new configuration coordinator. When the original node comes back up, it will preempt the new configuration coordinator and take over as the configuration coordinator. Note: When priority is not configured for any of the nodes or if multiple nodes have the same priority, the cluster elects one of the nodes as the configuration coordinator. Default value: 31 Minimum value: 0 Maximum value: 31
nodegroup The default node group in a Cluster system. Default value: DEFAULT_NG
delay Applicable for Passive node and node becomes passive after this timeout (in minutes) Default value: 0 Maximum value: 1440
tunnelmode To set the tunnel mode
Possible values: NONE, GRE, UDP Default value: NONE
Example
add cluster node 1 1.1.1.1 -backplane 1/1/1 -state ACTIVE
bind cluster node

Synopsis
bind cluster node
Arguments
nodeId A number that uniquely identifies the cluster node. Minimum value: 0 Maximum value: 31
routeMonitor Route Monitor
netmask The subnet mask associated with the IPv4 route specified by the routeMonitor parameter.
Example
bind cluster node 1 -routeMonitor 5.5.5.0 255.255.255.0
