7–RoCE Configuration
Preparing the Ethernet Switch
130 AH0054602-00 M
2. Configure the quality of service (QoS) class map and set the RoCE priority
(
cos) to match the adapter (5) as follows:
switch(config)# class-map type qos class-roce
switch(config)# match cos 5
3. Configure queuing class maps as follows:
switch(config)# class-map type queuing class-roce
switch(config)# match qos-group 3
4. Configure network QoS class maps as follows:
switch(config)# class-map type network-qos class-roce
switch(config)# match qos-group 3
5. Configure QoS policy maps as follows:
switch(config)# policy-map type qos roce
switch(config)# class type qos class-roce
switch(config)# set qos-group 3
6. Configure queuing policy maps to assign network bandwidth. In this
example, use a value of 50 percent:
switch(config)# policy-map type queuing roce
switch(config)# class type queuing class-roce
switch(config)# bandwidth percent 50
7. Configure network QoS policy maps to set priority flow control for no-drop
traffic class as follows:
switch(config)# policy-map type network-qos roce
switch(config)# class type network-qos class-roce
switch(config)# pause no-drop
8. Apply the new policy at the system level as follows:
switch(config)# system qos
switch(config)# service-policy type qos input roce
switch(config)# service-policy type queuing output roce
switch(config)# service-policy type queuing input roce
switch(config)# service-policy type network-qos roce
9. Assign a vLAN ID to the switch port to match the vLAN ID assigned to the
adapter (5).
switch(config)# interface ethernet x/x
switch(config)# switchport mode trunk
switch(config)# switchport trunk allowed vlan 1,5
