v. Configure qos policy-maps.
switch(config)#policy-map type qos policy-test
switch(config-pmap-qos)#class type qos class-nic
switch(config-pmap-c-qos)#set qos-group 2
vi. Configure queuing policy-maps and assign network bandwidth. Divide the network bandwidth
between FcoE and NIC traffic.
switch(config)#policy-map type queuing policy-test
switch(config-pmap-que)#class type queuing class-nic
switch(config-pmap-c-que)#bandwidth percent 50
switch(config-pmap-c-que)#class type queuing class-fcoe
switch(config-pmap-c-que)#bandwidth percent 50
switch(config-pmap-c-que)#class type queuing class-default
switch(config-pmap-c-que)#bandwidth percent 0
vii. Configure network-qos policy maps and set up the PFC for no-drop traffic class.
switch(config)#policy-map type network-qos policy-test
switch (config-pmap-nq)#class type network-qos class-nic
switch(config-pmap-nq-c)#pause no-drop
By default, FCoE is set to pause no drop. In such a trade off, one may want to set
Note
NIC to drop instead.
viii. Apply the new policy (PFC on NIC and FcoE traffic) to the entire system.
switch(config)#system qos
switch(config-sys-qos)#service-policy type qos input policy-test
switch(config-sys-qos)#service-policy type queuing output policy-test
switch(config-sys-qos)#service-policy type queuing input policy-test
switch(config-sys-qos)#service-policy type network-qos policy-test
Configuring the FCoE/FC Ports
In this procedure, you may need to adjust some of the parameters to suit your environment, such
as VLAN IDs, Ethernet interfaces, and virtual Fibre Channel interfaces
