PurposeCommand or Action
(Optional)
Disables the marking operation in this class.
switch(config-pmap-c-nq)# no set
cos cos-value
Step 13
This example shows how to define a type network-qos policy map:
switch# configure terminal
switch(config)# policy-map type network-qos policy-que1
switch(config-pmap-nq)# class type network-qos class-que1
switch(config-pmap-c-nq)# mtu 5000
switch(config-pmap-c-nq)# pause no-drop pfc-cos 1-3,5
switch(config-pmap-c-nq)# set cos 4
Configuring Type Queuing Policies
Type queuing policies 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
(except for Fabric Extender host interfaces) for input or output traffic.
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Creates a named object that represents a set of policies that
are to be applied to a set of traffic classes. Policy-map
switch(config)# policy-map type
queuing policy-name
Step 2
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.
switch(config-pmap-que)# class
type queuing class-name
Step 3
Specifies the guaranteed percentage of interface bandwidth
allocated to this class. By default, no bandwidth is specified
for a class.
switch(config-pmap-c-que)#
bandwidth percent percentage
Step 4
Before you can successfully allocate bandwidth
to the class, you must first reduce the default
bandwidth configuration on class-default and
class-fcoe.
Note
(Optional)
Removes the bandwidth specification from this class.
switch(config-pmap-c-que)# no
bandwidth percent percentage
Step 5
Specifies that traffic in this class is mapped to a strict
priority queue.
switch(config-pmap-c-que)#
priority
Step 6
Only one class in each policy map can have strict
priority set on it.
