Chapter 33 Configuring QoS
Configuring QoS
If you enter the
no
policy-map configuration command or the
no policy-map
policy-map-name
global
configuration command to delete a policy map that is attached to an interface, a warning message
appears that lists any interfaces from which the policy map is being detached. The policy map is then
detached and deleted. For example:
Warning: Detaching Policy test1 from Interface GigabitEthernet0/1
After you have created an input policy map, you attach it to an interface in the input direction. See the
“Attaching a Traffic Policy to an Interface” section on page 33-38
.
Use the
no
form of the appropriate command to delete an existing policy map, class map, or policer.

(Optional) Enter the action to be taken for packets that do not
conform to the CIR.
•
For
cos
cos_value,
enter a new CoS value to be assigned to the
classified traffic. The range is 0 to 7.
•
For [
ip
]
dscp
dscp_value
, enter a new DSCP value to be
assigned to the classified traffic. The range is 0 to 63.
•
For [
ip
]
precedence
precedence_value,
enter a new
IP-precedence value to be assigned to the classified traffic. The
range is 0 to 7.
•
Or you can configure a CoS, DSCP, or IP precedence table and
optionally enter the table name. If you do not enter
table
table-map name
, the table map default behavior is
copy
. See the
“Configuring Table Maps” section on page 33-36
.
•
For
qos-group
value,
identify a QoS group to be used at egress
to identify specific packets. The range is from 0 to 99.
Note
You can enter a single exceed-action as part of the command
string following the
police
command. Or you can press
Enter after the
police
command to enter policy-map class
police configuration mode, where you can enter multiple
actions. In policy-map class police configuration mode, you
must enter an action to take.
Note
If you explicitly configure
exceed-action drop
as keywords
in the command, you must enter policy-map class police
configuration mode and enter the
no exceed-action drop
command to remove the previously configured exceed
action before you can enter the new exceed-action.
Step 7
exit
Return to policy-map configuration mode.
Step 8
exit
Return to global configuration mode.
Step 9
interface
interface-id
Enter interface configuration mode for the interface to which you
want to attach the policy.
Step 10
service-policy input
policy-map-name
Attach the policy map (created in Step 2) to the ingress interface.
Step 11
end
Return to privileged EXEC mode.
Step 12
show policy-map
[
policy-map-name
[
class
class-map-name
]]
Verify your entries.
Step 13
copy running-config startup-config
(Optional) Save your entries in the configuration file.
