Usage
Information
To associate a priority group with an ETS output policy with scheduling and bandwidth configuration,
create a DCB output policy. You can apply a DCB output policy on multiple egress ports. When you apply
an ETS output policy on an interface, ETS-configured scheduling and bandwidth allocation take
precedence over any configured settings in QoS output policies.
The ETS configuration associated with 802.1 priority traffic in a DCB output policy is used in DCBX
negotiation with ETS peers.
