6. Applying policy maps to interfaces
a. Switch# conf t
b. Switch(config# inte ethe1/1/53 – interface part of iSCSI flows.
c. Switch(config-if-eth1/1/53)# switchport mode trunk
d. Switch(config-if-eth1/1/53)# switchport trunk allowed vlan 100,200 – LAN and iSCSI traffic
allowed in this interface.
e. Switch(config-if-eth1/1/53)# service-policy input type network-qos temp
Service policy that turns on PFC on CoS = 4. Policy map in step 5b.
f. Switch(config-if-eth1/1/53)# service-policy input type qos trust_dot1p
QoS policy that trusts the system’s dot1p settings
g. Switch(config-if-eth1/1/53)# service-policy output type queuing q1
Egress service policy applying ETS on output queues defined in step 5a.
h. Switch(config-if-eth1/1/53)# ets mode on
Turns “ON” ETS
i. Switch(config-if-eth1/1/53)# qos-map traffic-class qmap
Assigns the system queues to the proper class of service value on ingress
j. Switch(config-if-eth1/1/53)# priority-flow-control mode on
PFC is turned “ON” at the interface
k. Switch(config-if-eth1/1/53)# end
l. Switch#
Note: Apply configurations in step 6 on all switches (OS10) and interfaces that are participating in the
transmission and reception of LAN and iSCSI traffic.
