ONTAP 9.14.1 commands

security login banner modify

Modify the login banner message

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


The security login banner modify command modifies the login banner. The login banner is printed just before the authentication step during the SSH and console device login process.


-vserver <Vserver Name> - Vserver Name

Use this parameter to specify the Vserver whose banner will be modified. Use the name of the cluster admin Vserver to modify the cluster-level message. The cluster-level message is used as the default for data Vservers that do not have a message defined.

{ [-message <text>] - Login Banner Message

This optional parameter can be used to specify a login banner message. If the cluster has a login banner message set, the cluster login banner will be used by all data Vservers as well. Setting a data Vserver’s login banner will override the display of the cluster login banner. To reset a data Vserver’s login banner to use the cluster login banner, use this parameter with the value "-" .

If you use this parameter, the login banner cannot contain newlines (also known as end of lines (EOLs) or line breaks). To enter a login banner message with newlines, do not specify any parameter. You will be prompted to enter the message interactively. Messages entered interactively can contain newlines.

Non-ASCII characters must be provided as Unicode UTF-8.

| [-uri {scheme://(hostname|IPv4 Address|'['IPv6 Address']')…​}] - Download URI for the Banner Message }

Use this parameter to specify the URI from where the login banner will be downloaded. Note that the message must not exceed 2048 bytes in length. Non-ASCII characters must be provided as Unicode UTF-8.


This example shows how to enter a login banner interactively:

cluster1::> security login banner modify
Enter the login banner for Vserver "cluster1".
Max size: 2048. Enter a blank line to terminate input. Press Ctrl-C to abort.
