Configuring the Cisco Nexus 6000 Ethernet Switch for RoCE comprises
configuring class maps, configuring policy maps, applying the policy, and
assigning a VLAN ID to the switch port.
1. Open a config terminal session.
Switch# config terminal
switch(config)#
2. Configure quality of service (QoS) class maps, setting the RoCE priority to
match the adapter (5).
switch(config)# class-map type qos class-roce
switch(config)# match cos 5
3. Configure queuing class maps.
switch(config)# class-map type queuing class-roce
switch(config)# match qos-group 3
4. Configure network QoS class maps.
switch(config)# class-map type network-qos class-ro
switch(config)# match qos-group 3
5. Configure QoS policy maps.
switch(config)# policy-map type qos roce
switch(config)# class type qos class-roc
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
