Reference Guide

• In a port, one H2 node and three H1 nodes are supported. The H1 node holds 8 unicast queues for data trac, 8 unicast queues for
control trac, and 8 multicast queues for data trac.
• The H1 nodes mapped to data trac are scheduled with DWRR and weight of 50 each. The H1 node mapped to control trac is
scheduled with strict priority.
• The weights corresponding to each trac class are applied at queue levels for both unicast and multicast queues.
• The bandwidth distribution might go to a minimum of 50, based on the trac ow in a port. This is determined by the weight of a
particular trac class and trac type.
• The bandwidth sharing based on ETS happens only between same type of queues.
• You can enable strict priority queuing only for the same type of trac.
Create class-map
1 Create a class-map, and congure a name for the class-map in CONFIGURATION mode.
class-map type queuing class-map-name
2 Congure a match criteria in CLASS-MAP mode.
match queue queue-id
Dene a policy-map
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 the strict priority in POLICY-MAP-CLASS-MAP mode.
priority
Apply policy-map
1 You can now apply the policy-map to the interface (INTERFACE mode) or all interfaces—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-queuing)# exit
OS10(config)# system qos
OS10(conf-sys-qos)# service-policy output solar
View QoS system

Enable strict priority on interface
