6 Dell EMC Networking – Deploying Native FC and FCoE on single S4148U-ON | 1.0
Fibre-Channel over Ethernet Configuration
6. The configurations from steps 1-5 apply for straight native Fibre-channel deployment on the S4148U. The
subsequent configuration steps apply to Fibre-channel over Ethernet deployment.
a. Switch# conf t
b. Switch(config)# policy-map type qos test
c. Switch(config-pmap-qos)# class class-trust
d. Switch(config-pmap-qos)# trust dot1p
e. Switch(config-pmap-qos)# end
f. Switch#
7. Using the previously configured policy map that trusts incoming dot1p’s values, turn on ETS (Enhanced
Transmission Selection) system wide.
a. Switch# conf t
b. Switch(config)# system qos
c. Switch(config-sys-qos)# ets mode on
d. Switch(config-sys-qos)# service-policy input type qos test
e. Switch(config-sys-qos)# end
f. Switch#
8. Configure a qos map consisting of two queues (queue 1 – LAN traffic, queue 3 – FCoE traffic). Assign
each queue to a different qos group. The same qos map will be applied on all interfaces expected to
receive FCoE traffic.
a. Switch# conf t
b. Switch(config)# qos-map traffic-class TC-Q
c. Switch(config-qos-map)# queue 1 qos-group 0-2,4-7
d. Switch(config-qos-map)# queue 3 qos-group 3
e. Switch(config-qos-map)# end
f. Switch#
9. Create queueing class maps that uses the qos-map defined in step 8.
a. Switch# conf t
b. Switch(config)# class-map type queueing LAN
c. Switch(config-cmap-queuing)# match queue 1
d. Switch(config-cmap-queuing)# exit
e. Switch(config)# class-map type queueing FCoE
f. Switch(config-cmap-map)# match queue 3
g. Switch(config-cmap-map)# end
h. Switch#
10. Create policy map that uses the class maps defined in step 9 and assign a percentage of the link
bandwidth to the specific traffic type defined by the class maps (LAN and FCoE).
a. Switch# conf t
b. Switch(config)# policy-map type queuing ETS
c. Switch(config-pmap-queuing)# class LAN
d. Switch(config-pmap-c-que)# bandwidth percent 10
e. Switch(config-pmap-c-que)# exit
f. Switch(config-pmap-queuing)# class FCoE
g. Switch(config-pmap-c-que)# bandwidth percent 90
