ONTAP 9.14.1 commands

system node virtual-machine show-network-load-balancer

Display network load balancer information

Availability: This command is available to cluster administrators at the advanced privilege level.


The system node virtual-machine show-network-load-balancer displays the list of network load balancer probe ports for each ONTAP node in the cluster.


{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-node <nodename>] - Node

Represents the name of the ONTAP node for which information is to be displayed. If this parameter is not specified, the command displays information about all nodes in the cluster.

[-vserver-name <text>] - Vserver Name

Vserver name.

[-lif-name <text>] - ONTAP LIF Name

ONTAP logical interface name.

[-probe-port <integer>] - Probe Port

A TCP port which is regularly probed by the network load balancer. When the TCP port is healthy and open, the network load balancer will continue sending traffic to an associated network route. When unhealthy, the network load balancer will redirect all traffic intended for this route to an alternate route.

[-last-probe-time <MM/DD/YYYY HH:MM:SS>] - Last Probe Time

The timestamp of the most recent health probe request on this TCP port.

[-remove-listener {true|false}] - Remove listener for This LIF

Whether or not ONTAP has programmatically told the network load balancer to stop listening on the health probe associated with this LIF.

[-active {true|false}] - Actively receiving Health Probes

Whether or not the network load balanacer has received a health probe request on this TCP port, within the expecteced timeframe.


The following example displays probe ports for each node in the cluster.
