You can set ETS feature attributes. But whether your configuration takes effect depends on the willing state on both local and remote side. This example configures a total of three groups with bandwidths of 40%, 20%, and 40%.
When the local willing state is false, the new configuration changes local operational status, but changes the remote configuration only if the remote willing state is true.

Local willing state is false and remote willing state is true, so local configuration change is used on both the local switch and the remote Oracle Solaris server.

Since the ETS is asymmetric, when the local willing state is true, the local switch blindly accepts the remote configuration.
The operational and remote configuration is not affected.

The local operational status has been changed to the remote configuration once the willing state is changed. If the configuration is changed again on the switch, the operational status and remote configuration is not affected.

The operational configuration is changed back to the admin configuration once the local willing state is set to false.
The operational operation also is changed.
