Strict priority queuing
OS10 uses queues for egress QoS policy types. Enable strict priority to dequeue all packets from the assigned queue before
servicing any other queues. When you assign more than one queue strict priority, the highest number queue receives the highest
priority. You can configure strict priority to any number of queues. By default, all queues schedule traffic per WDRR.
Use the priority command to assign the priority to a single unicast queue—this configuration supersedes the bandwidth
percent configuration. A queue with priority enabled can starve other queues for the same egress interface.
Create class-map
1. Create a class-map and configure a name for the class-map in CONFIGURATION mode.
class-map type queuing class-map-name
2. Configure a match criteria in CLASS-MAP mode.
match queue queue-id
Define a policy-map
1. Define a policy-map and create a policy-map name CONFIGURATION mode.
policy-map type queuing policy-map-name
2. Create a queuing class and configure 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.
