Strict priority queuing
OS10 uses queues for egress QoS policy-types. You can enable priorities to dequeue all packets from the assigned queue before servicing
any other queues. When more than one queue is assigned strict priority, the highest number queue receives the highest priority. You can
congure strict priority to any number of queues. By default, all queues schedule trac per WDRR.
You can use the priority command to assign the priority to a single unicast queue—this conguration supersedes the bandwidth
percent
conguration. A queue with priority enabled can starve other queues for the same egress interface.
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.

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
