Configuring Type Queuing Policies

Type queuing policies for egress are used for scheduling and buffering the traffic of a specific system class.
A type queuing policy is identified by its QoS group and can be attached to the system or to individual interfaces
for input or output traffic.
Ingress queuing policy is used to configure pause buffer thresholds. For more details, see the

Purpose
Enters global configuration mode.
Creates a named object that represents a set of policies that are to be applied to a
set of traffic classes. Policy-map names can contain alphabetic, hyphen, or underscore
characters, are case sensitive, and can be up to 40 characters.
Associates a class map with the policy map, and enters configuration mode for the
specified system class.
Specifies that traffic in this class is mapped to a strict priority queue.
(Optional) Removes the strict priority queuing from the traffic in this class.
Specifies the burst size and minimum guaranteed bandwidth for this queue.
Assigns a weight to the class. The class will receive the assigned percentage of
interface bandwidth if there are no strict-priority queues. If there are strict-priority
queues, however, the strict-priority queues receive their share of the bandwidth
first. The remaining bandwidth is shared in a weighted manner among the class
