Chapter 37 Configuring QoS
Configuring Standard QoS
Classifying Traffic by Using Class Maps and Filtering IPv6 Traffic
The switch supports both IPv4 and IPv6 QoS when a dual-ipv4-and-ipv6 SDM template is configured.
When the dual IP SDM template is configured, the
match ip dscp
and
match ip precedence
classifications match both IPv4 and IPv6 traffic. The
match protocol
command allows you to create a
secondary match classification that filters traffic by IP version (IPv4 or IPv6).
To apply the primary match criteria to only IPv4 traffic, use the
match protoco
l command with the
ip
keyword. To apply the primary match criteria to only IPv6 traffic, use the
match protocol
command with
the
ipv6
keyword. For more information about the
match protocol
command, see the
of Service Solutions Command Reference
.
Beginning in privileged EXEC mode, follow these steps to create a class map, define the match criterion
to classify traffic, and filter IPv6 traffic:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
class-map
{
match-all
}
class-map-name
Create a class map, and enter class-map configuration mode.
By default, no class maps are defined.
When you use the
match protocol
command, only the
match-all
keyword is supported.
•
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
.
Step 3
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.
For more information about the
match protocol
command, see the
Cisco IOS Quality of Service Solutions Command Reference
Step 4
match
{
ip dscp
dscp-list
|
ip precedence
ip-precedence-list
}
Define the match criterion to classify traffic.
By default, no match criterion is defined.
•
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.
