Parameter

Description

Value

name vsi-name

Usage Guidelines

Usage Scenario

In the display vsi command:

If vsi-name is specified, information about a specified VSI is displayed.
If vsi-name is not specified, information about all VSIs is displayed.

Precautions

If the output of the display vsi [ name vsi-name ] [ verbose ] command does not contain PW information, no PW is set up for this VSI. This command displays only the information about the VSI on the local end.

To view information about the VSI on the remote end, run the display vsi remote command.

Example

The actual command output varies according to the device. The command output here is only an example.
