Display the calibration measurements for local nodes in MetroCluster over IP configuration

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

Description

The metrocluster configuration-settings calibration show command shows the bandwidth and latency between local and remote nodes in a MetroCluster over IP configuration.

Parameters

{ [-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.

[-calibration-id <integer>] - Calibration ID

This field specifies Calibration ID.

[-subnet <IP Address>] - IP Subnet

This field specifies subnet.

[-node-uuid <UUID>] - Node UUID

This field specifies UUID of the node.

[-home-port {<netport>|<ifgrp>}] - Home Port

This field specifies name of the port used to measure latency and bandwidth.

[-node {<nodename>|local}] - Node Name

This field specifies name of the node.

[-collection-time <MM/DD/YYYY HH:MM:SS>] - Collection Time of Sample

This field specifies collection time of sample.

[-source-address <IP Address>] - Source Network Address

This field specifies IP address of the port on the node.

[-destination-address <IP Address>] - Destination Network Address

This field specifies IP address of the port on the partner node.

[-latency <double>] - Latency in ms

This field specifies latency in ms.

[-bandwidth <double>] - Bandwidth in Mb/s

This field specifies bandwidth in Mb/s.

[-num-packets-retransmitted <integer>] - Number of Packets Retransmitted

This field specifies the number of TCP packets retransmitted during bandwidth measurement.

[-pct-pkt-retrans <double>] - Percentage of packages retransmitted

This field specifies the percent of TCP packets retransmitted during bandwidth measurement.
