4 Create a queuing type policy-map and congure a policy-map name in CONFIGURATION mode.
policy-map type queuing policy-map-name
5 Congure a queuing class in POLICY-MAP mode.
class class-name
6 Assign a bandwidth percent, from 1 to 100 to nonpriority queues in POLICY-MAP-CLASS-MAP mode.

Strict priority queuing
OS10 uses queues for egress QoS policy types. Enable priorities 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 congure
strict priority to any number of queues. By default, all queues schedule trac per WDRR.
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.
Consider the following when enabling priority queueing in S5148F-ON:
• 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.
