Cisco ME 3400 Ethernet Access Switch Software Configuration Guide
OL-9639-07
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.
Step 6
exceed-action cos {cos_value | cos [table
table-map-name] | dscp [table
table-map-name] | precedence [table
table-map-name]}
or
exceed-action [ip] dscp {dscp_value | cos
[table table-map-name] | dscp [table
table-map-name] | precedence [table
table-map-name]}
or
exceed-action [ip] precedence
{precedence_value | cos [table
table-map-name] | dscp [table
table-map-name] | precedence [table
table-map-name]}
or
exceed-action qos-group value
(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.
