qos-policy-output ets

To configure the ETS bandwidth allocation and scheduling for priority traffic, create a QoS output policy.

qos-policy-output policy-name ets

To remove the QoS output policy, use the no qos-policy-output ets command.

Enter the policy name. The maximum is 32 characters.

Usage Information

If an error occurs in an ETS output-policy configuration, the configuration is ignored and the scheduler and bandwidth allocation settings are reset to the ETS default values (all priorities are in the same ETS priority group and bandwidth is allocated equally to each priority).

If an error occurs when a port receives a peer’s ETS configuration, the port’s configuration is reset to the previously configured ETS output policy. If no ETS output policy was previously applied, the port is reset to the default ETS parameters.

You can only associate output QoS policy profiles with the priority groups in the DCB output profile context; output QoS policy profiles are not permitted on output policy-maps.

WRED, ECN, rate shaping, and rate limiting are not supported in output policies because DCBx does not negotiate these parameters with peer devices. You can apply a QoS output policy with WRED and/or rate shaping on a DCBx CIN-enabled interface.

If you enable the scheduler command for a QoS ETS output policy, no bandwidth percentage is assigned to the policy.
