Configuring Bandwidth Allocation For Dcbx Cin - Dell Force10 S4810P Configuration Manual

- The priority group for strict-priority scheduling (
Output
If you configure only the priority group in an ETS output policy or only the dot1p priority for
strict-priority scheduling, the flow is handled with group strict priority.

Configuring Bandwidth Allocation for DCBx CIN

After you apply an ETS output policy to an interface, if the DCBx version used in your data center network
is CIN, you may need to configure a QoS output policy to overwrite the default CIN bandwidth allocation.
This default setting divides the bandwidth allocated to each port queue equally between the dot1p priority
traffic assigned to the queue.
For more information, refer to
To create a QoS output policy that allocates different amounts of bandwidth to the different traffic types/
dot1p priorities assigned to a queue and apply the output policy to the interface, follow these steps.
Step Task
1 Create a QoS output policy.
Maximum: 32 alphanumeric characters.
2 Configure the percentage of bandwidth to be
allocated to the dot1p priority/queue traffic in
the associated L2 class map.
Default: None.
3 Repeat Step 2 to configure bandwidth
percentages for other priority queues on the
port.
4 Exit QoS Output Policy Configuration mode.
5 Enter INTERFACE Configuration mode.
6 Apply the QoS output policy with the
bandwidth percentage for specified priority
queues to an egress interface.
