Configure DCB ETS Attributes

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.

  1. View the original configuration before any change is made.

    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.

  2. Configure ETS with different bandwidth allocation.
    SEFOS# configure terminal
    SEFOS(config)# interface extreme-ethernet 0/21

  3. View the configuration to verify that the configuration changes have been applied to both the local and remote systems.

    Since the ETS is asymmetric, when the local willing state is true, the local switch blindly accepts the remote configuration.

  6. Change the configuration again on the switch.

    The operational and remote configuration is not affected.

  7. Change the willing state so that local willing is true and remote willing is false.

    Since local willing state has already been set to true, type the following Oracle Solaris commands to change the remote willing state to false.

    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.
