1. Define a class map of QoS policies on the first switch to identify the iSCSI traffic (here, iSCSI traffic is
matched to class-of-service [CoS] 5):
N5548-Bottom(config)# class-map type qos match-all iSCSI-C1
N5548-Bottom(config-cmap-qos)# match protocol iscsi
N5548-Bottom(config-cmap-qos)# match cos 5
2. Configure the type of QoS policies used to classify the traffic of a specific system class (here, the
QoS-group value 2 is used):
N5548-Bottom(config)# policy-map type qos iSCSI-C1
N5548-Bottom(config-pmap-qos) class iSCSI-C1
N5548-Bottom(config-pmap-c-qos)# set qos-group 2
N5548-Bottom(config-pmap-c-qos)# exit
N5548-Bottom(config-pmap-c-qos)# class class-default
3. Configure the no-drop policy maps:
N5548-Bottom(config)# class-map type network-qos iSCSI-C1
N5548-Bottom(config-cmap-nq)# match qos-group 2
N5548-Bottom(config-cmap-nq)# exit
N5548-Bottom(config)# policy-map type network-qos iSCSI-C1
N5548-Bottom(config-pmap-nq)# class type network-qos iSCSI-C1
N5548-Bottom(config-pmap-nq-c)# pause no-drop
N5548-Bottom(config-pmap-nq-c)# class type network-qos class-default
N5548-Bottom(config-pmap-nq-c)# mtu 9216
4. Apply the system service policies:
N5548-Bottom(config-sys-qos)# service-policy type qos input iSCSI-C1
N5548-Bottom(config-sys-qos)# service-policy type network-qos iSCSI-C1
5. Identify the iSCSI traffic on the other Cisco Nexus switch using the same process as for the first
switch by defining a class map for each class of traffic to be used in the QoS policies:
N5548-Top(config)# class-map type qos match-all iSCSI-C1
N5548-Top(config-cmap-qos)# match protocol iscsi
N5548-Top(config-cmap-qos)# match cos 5
6. Configure the QoS policy type:
N5548-Top(config)# policy-map type qos iSCSI-C1
N5548-Top(config-pmap-qos) class iSCSI-C1
N5548-Top(config-pmap-c-qos)# set qos-group 2
N5548-Top(config-pmap-c-qos)# exit
N5548-Top(config-pmap-c-qos)# class class-default
