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.
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.
1 Create a QoS output policy.
CONFIGURATION mode
Dell(conf)#qos-policy-output test12
The maximum 32 alphanumeric characters.
2 Configure the percentage of bandwidth to allocate to the dot1p priority/queue traffic in the associated
L2 class map.
QoS OUTPUT POLICY mode
Dell(conf-qos-policy-out)#bandwidth-percentage 100
The default is none .
3 Repeat Step 2 to configure bandwidth percentages for other priority queues on the port.
QoS OUTPUT POLICY mode
Dell(conf-qos-policy-out)#bandwidth-percentage 100
4 Exit QoS Output Policy Configuration mode.
QoS OUTPUT POLICY mode
Dell(conf-if-te-0/1)#exit
5 Enter INTERFACE Configuration mode.
CONFIGURATION mode
interface type slot/port
6 Apply the QoS output policy with the bandwidth percentage for specified priority queues to an egress
interface.
INTERFACE mode
Dell(conf-if-te-0/1)#service-policy output test12
