Configuration Guidelines
Take the following steps to configure ETS:
1. Map CoS queues to TCGs for the egress ports using the traffic-class map
command.
2. Configure the bandwidth allocation for all TCGs using the traffic-class weight
command.
3. Enable the required scheduling algorithm for each TCG using the traffic-class
algo command.
4. Ensure that the 802.1p priority present in the frames entering the ingress ports
is set to be trusted using the qos map trust-mode command.
5. Set the ETS mode to auto-negotiation through DCBX or force it into on state
using the ets mode command.
ets mode Use this command to set the ETS mode to negotiate capability through DCBX or by
forcing it to on state. Use the no form to restore the default setting.
