1 Dene a policy-map and create a policy-map name CONFIGURATION mode.
policy-map type queuing policy-map-name
2 Create a QoS class and congure a name for the policy-map in POLICY-MAP mode.
class class-map-name
3 Set the scheduler as strict priority in POLICY-MAP-CLASS-MAP mode.
priority
Apply policy-map
1 Apply the policy-map to the interface in INTERFACE mode or all interfaces in SYSTEM-QOS mode.
system qos
OR
interface ethernet node/slot/port[:subport]
2 Enter the output service-policy in SYSTEM-QOS mode or INTERFACE mode.
service-policy {output} type {queuing} policy-map-name
Enable strict priority on class-map
OS10(config)# class-map type queuing magnum
OS10(conf-cmap-queuing)# match queue 7
OS10(conf-cmap-queuing)# exit
OS10(config)# policy-map type queuing solar
OS10(conf-pmap-queuing)# class magnum
OS10(conf-pmap-c-que)# priority
OS10(conf-pmap-c-que)# exit
OS10(conf-pmap-queuing)# exit
OS10(config)# system qos
OS10(conf-sys-qos)# service-policy output solar
View QoS system
OS10(conf-sys-qos)# do show qos system
Service-policy (output)(queuing): solar
Enable strict priority on interface
OS10(config)# interface ethernet 1/1/5
OS10(conf-if-eth1/1/5)# service-policy output type queuing solar
View policy-map
OS10(conf-if-eth1/1/5)# do show policy-map
Service-policy(queuing) output: solar
Class-map (queuing): magnum

Rate adjustment
QoS features such as policing and shaping do not include overhead elds such as Preamble, smart frame delimiter (SFD), inter-frame gap
(IFG), and so on. For rate calculations, these feature only include the frame length between the destination MAC address (DMAC) and the
CRC eld.
You can optionally include the following overhead elds in rate calculations by enabling rate adjustment:
• Preamble—7 bytes
• Start frame delimiter—1 byte
• Destination MAC address—6 bytes
• Source MAC address—6 bytes
• Ethernet type/length—2 bytes
