DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide By default, 0 is assigned for Traffic Class 7 which means that the transmission selection algorithm is "strict priority". Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline The ETS bandwidth assignment only takes effect when the scheduling mode is ETS. Example This example shows how to assign available bandwidth to traffic classes for the ETS scheduling mode on ethernet 1/0/3. This example allocates 10%, 20%, 30%, and 40% available bandwidth to traffic classes 0 to 3. Assign traffic class 4 to 7 to strict priority. Switch# configure terminal Switch(config)# interface ethernet 1/0/3 Switch(config-if)# mls qos scheduler ets Switch(config-if)# ets-queue bandwidth 10 20 30 40 0 0 0 0 Switch(config-if)# 82-4 mls qos scheduler ets This command is used to configure the queue scheduling to the Enhanced Transmission Selection (ETS) mode. mls qos scheduler ets Parameters None. Default None. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline ETS is defined in IEEE 802.1Qaz. ETS provides an operational model for priority processing and bandwidth allocation in the switches in a DCB environment. Using priority-based processing and bandwidth allocations, different traffic classes with different types of traffic such as LAN, Storage Networking, Clustering, and management can be configured to provide bandwidth allocation or best effort transmit characteristics. When the offered load in the traffic class doesn't use its allocated bandwidth, ETS will allow other traffic classes to use the available bandwidth. The bandwidth assigned to each traffic class is configured in unit of percentage by the etsqueue bandwidth command. 790
