network test-link run-test
Test link bandwidth
Description
The network test-link run-test command runs a performance test between two nodes. The command requires a source node, Vserver, and destination address.
Before executing the network test-link run-test command, the network test-link start-server command must be run to start a server on the node hosting the destination LIF. After all tests to that node are complete the network test-link stop-server command must be run to stop the server.
The test results are stored non-persistently and can be viewed using the network test-link show command. Results include input parameters, the bandwidth achieved, and the date and time of the test.
Parameters
- -node {<nodename>|local} - Node Name
- Use this parameter to specify the node which initiates the test.
- -vserver <vserver> - Vserver
- Use this parameter to specify the Vserver to access the destination LIF. DC (Data Channel) Vserver option is available only in an ONTAP Select or ONTAP Cloud cluster. It is a special vserver that hosts LIFs that are used to mirror data aggregates to partner node.
- -destination <Remote InetAddress> - Destination
- Use this parameter to specify the destination IP address.
Examples
The following example runs a test between the cluster LIFs, including the start and stop of the server side of the test:
cluster1::*> network test-link start-server -node node1
cluster1::*> network test-link run-test -node node2 -vserver Cluster -destination 172.31.112.173
Node: node2
Vserver: Cluster
Destination: 172.31.112.173
Time of Test: 4/22/2020 15:33:18
MB/s: 41.2678
cluster1::*> network test-link stop-server -node node1
cluster1::*> network test-link show
