Users Guide

(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.
