6. Start configuring the class maps to be used with all respective policy maps – first one
“queueing”.
4a. Queueing – This queues refer to the queues configured in step 3.
a. Switch# conf t
b. Switch(config)# class-map type queueing q0
c. Switch(config-cmap-queuing)# match queue 0
d. Switch(config-cmap-queuing)# exit
e. Switch(config)# class-map type queuing q4
f. Switch(config-cmap-queuing)# match queue 4
g. Switch(config-cmap-queuing)# exit
h. Switch(config)# class-map type queuing q5
i. Switch(confg-cmap-queuing)# match queue 5
j. Switch(config-cmap-queuing)# exit
k. Switch(config)#
4b. Network-qos – This class map is used by the service policy input and applied as
ingress traffic. (see “Interface configuration” in step 8)
a. Switch# conf t
b. Switch(config)# class-map type network-qos iSCSI
c. Switch(config-cmap-nqos)# match qos-group 4
d. Switch(config-cmap-nqos)# exit
e. Switch(config-cmap)# class-map type network-qos RoCEv1
f. Switch(config-cmpa-nqos)# match qos-group 5
g. Switch(config-cmap-nqos)# end
h. Switch#
7. Start configuring the relevant policy maps which will use the class-maps defined in
steps 3-4 and self-generated class “class-trust”.
a. Switch# conf t
b. Switch(config)# policy-map type qos trust_dot1p
c. Switch(config-pmap-qos)# class class-trust
d. Switch(config-pmap-c-qos)# trust dot1p
e. Switch(config-pmap-c-qos)# end
f. Switch#
5a. ETS policy map – Assigning bandwidth percentage to each queue.
a. Switch# conf t
b. Switch(config)# policy-map type queuing q1
