Chapter 24 Configuring QoS
Beginning in privileged EXEC mode, follow these steps to create a policy map:
Command
Step 1
configure terminal
Step 2
access-list access-list-number {deny |
permit} {source source-wildcard | host
source | any}
or
access-list access-list-number
{deny | permit | remark} protocol
{source source-wildcard | host source |
any } [operator port] {destination
destination-wildcard | host destination |
any} [operator port]
or
mac access-list extended name
(deny | permit} {any | host source MAC
address} {any | host destination MAC
address} [aarp | amber | appletalk
|dec-spanning | decnet-iv | diagnostic |
dsm | etype-6000 | etype-8042 | lat |
lavc-sca | mop-console | mop-dump |
msdos | mumps | netbios | vines-echo

Step 3 policy-map policy-map-name
Step 4
class class-map-name [ access-group name
acl-index-or-name ]

Purpose
Enter global configuration mode.
Create an IP standard or extended ACL for IP traffic or a Layer 2 MAC
ACL for non-IP traffic, repeating the command as many times as
necessary.
For more information, see the
section on page 24-14.
Note Deny statements are not supported for QoS ACLS. See the
"Classification Based on QoS ACLs" section on page 24-5
more details.
For more information on this command, see the
Extended ACLs" section on page
Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
By default, no policy maps are defined.
The default behavior of a policy map is to set the DSCP to 0 if the
packet is an IP packet and to set the CoS to 0 if the packet is tagged. No
policing is performed.
Define a traffic classification, and enter policy-map class configuration
mode.
By default, no policy map class maps are defined.
If a traffic class has already been defined by using the class-map global
configuration command, specify its name for class-map-name in this
command.
For access-group acl-index-or-name , specify t he number or name of the
ACL created in Step 2.
In a policy map, the class named class-default is not supported.
Note
The switch does not filter traffic based on the policy map
defined by the class class-default policy-map configuration
command.
