• Disable – scheduling mode is Strict Priority (SP)
• Bandwidth percentage for each traffic class: By de
fault each traffic class gets an equal
share
The default mapping of priority to traffic clas
ses (per interface) is as follows:
• Priority 0,1 mapped to tc 0
• Priority 2,3 mapped to tc 1
• Priority 4,5 mapped to tc 2
• Priority 6,7 mapped to tc 3
ETS is enabled by default (
scheduling is WRR).
 To set the scheduling mode to Strict Priority:
Step 1. Log in as admin.
Step 2. Enter config mode. Run:
Step 3. Run the command dcb ets disable .
 To configure the WRR bandwidth percentage:
Step 1. Log in as admin.
Step 2. Enter config mode. Run:
Step 3. Make sure ETS feature is enabled. Run:
Step 4. Choose the WRR bandwidth rate and distribution.
By default the WRR distribution function is equal 25% per TC. Changing the WRR bandwidth
rate will cause a change in the distribution function, for example if you wish to schedule more
traffic on TC-0, TC-1, TC-2 while reducing the amount of traffic sent on TC-3, run the com-
mand
dcb ets tc bandwidth .
