Chapter 32 Configuring QoS
Configuring Standard QoS
•
The hierarchical policy map is attached to the SVI and affects all traffic belonging to the VLAN.
The actions specified in the VLAN-level policy map affect the traffic belonging to the SVI. The
police action on the port-level policy map affects the ingress traffic on the affected physical
interfaces.
•
When configuring a hierarchical policy map on trunk ports, the VLAN ranges must not overlap. If
the ranges overlap, the actions specified in the policy map affect the incoming and outgoing traffic
on the overlapped VLANs.
•
Aggregate policers are not supported in hierarchical policy maps.
•
When VLAN-based QoS is enabled, the switch supports VLAN-based features, such as the VLAN
map.
•
You can configure a hierarchical policy map only on the primary VLAN of a private VLAN.
Beginning in privileged EXEC mode, follow these steps to create a hierarchical policy map:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
class-map
[
match-all
|
match-any
]
class-map-name
Create a VLAN-level class map, and enter class-map configuration
mode. For information about creating a class map, see the
“Classifying
Traffic by Using Class Maps” section on page 32-46
.
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 3
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.
•
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 4
exit
Return to class-map configuration mode.
