security ssh prepare-to-downgrade

Restore SSH configuration to releases earlier than Data ONTAP 9.0.0.

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

Description

The security ssh prepare-to-downgrade command restores the configurations of SSH key exchange algorithms and ciphers of all Vservers and the cluster to their default settings prior to ONTAP 9.0. This command also disables the MAC configuration capability. You must run this command in advanced privilege mode when prompted to do so during the release downgrade. Otherwise, the release downgrade process will fail.

Examples

The following command restores the SSH security configurations of all Vservers and the cluster to the settings used before ONTAP 9.0.
cluster1::*> security ssh prepare-to-downgrade
