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 (refer to Configuring Port-
Based Rate Shaping and Weighted Random Early Detection).
If you enable the scheduler command for a QoS ETS output policy, no bandwidth
percentage is assigned to the policy.
