Chapter 37 Configuring QoS
Configuring Standard QoS
To delete an existing policy map, use the
no policy-map
policy-map-name
global configuration
command. To delete an existing class map, use the
no class-map
[
match-all
|
match-any
]
class-map-name
global configuration command. To remove a match criterion, use the
no match
{
access-group
acl-index-or-name
|
ip dscp
|
ip precedence
} class-map configuration command.
This example shows how to configure the class map called
class1
. The
class1
has one match criterion,
which is access list 103. It permits traffic from any host to any destination that matches a DSCP value
of 10.
Switch(config)#
access-list 103 permit ip any any dscp 10
Switch(config)#
class-map class1
Switch(config-cmap)#
match access-group 103
Switch(config-cmap)#
end
Switch#
Step 4
match protocol
[
ip
|
ipv6
]
(Optional) Specify the IP protocol to which the class map applies.
•
Use the argument
ip
to specify IPv4 traffic, and
ipv6
to specify
IPv6 traffic.
•
When you use the
match protocol
command, only the
match-all
keyword is supported for the
class-map
command.
Note
This command is available only when the dual IPv4 and IPv6
SDM template is configured.
You can use the
match protocol
command with the
match ip dscp
or
match precedence
commands, but not with the
match access-group
command.
For more information about the
match protocol
command, see the
Cisco IOS Quality of Service Solutions Command Reference
.
Step 5
match
{
access-group
acl-index-or-name
|
ip dscp
dscp-list
|
ip precedence
ip-precedence-list
}
Define the match criterion to classify traffic.
By default, no match criterion is defined.
Only one match criterion per class map is supported, and only one ACL
per class map is supported.
•
For
access-group
acl-index-or-name,
specify the number or name
of the ACL created in Step 2.
•
To filter IPv6 traffic with the
match access-group
command,
create an IPv6 ACL, as described in Step 2.
•
For
ip dscp
dscp-list
, enter a list of up to eight IP DSCP values to
match against incoming packets. Separate each value with a space.
The range is 0 to 63.
•
For
ip precedence
ip-precedence-list
, enter a list of up to eight
IP-precedence values to match against incoming packets. Separate
each value with a space. The range is 0 to 7.
Step 6
end
Return to privileged EXEC mode.
Step 7
show class-map
Verify your entries.
Step 8
copy running-config startup-config
(Optional) Save your entries in the configuration file.
