Chapter 36 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 3
class-map
[
match-all
|
match-any
]
class-map-name
Create a class map, and enter class-map configuration mode.
By default, no class maps are defined.
•
(Optional) Use the
match-all
keyword to perform a logical-AND
of all matching statements under this class map. All match criteria
in the class map must be matched.
•
(Optional) Use the
match-any
keyword to perform a logical-OR
of all matching statements under this class map. One or more
match criteria must be matched.
•
For
class-map-name
, specify the name of the class map.
If neither the
match-all
or
match-any
keyword is specified, the
default is
match-all
.
Note
Because only one
match
command per class map is supported,
the
match-all
and
match-any
keywords function the same.
Step 4
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.
•
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 5
end
Return to privileged EXEC mode.
Step 6
show class-map
Verify your entries.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.
