Step 2
Router(config-pmap)#
class
class-map-name
Assigns the traffic class you specify to the policy map. Enters
policy-map class configuration mode.
class-map-name
is the name of a previously configured class map
and is the traffic class for which you want to define QoS actions.
Note
Repeat Steps 2 through 6 for each traffic class you want
to include in the child policy map. For information about
other QoS actions you can specify for the traffic classes,
see the
“Input and Output Policy Actions”
section in the
“Configuring QoS Policy Actions and Rules” chapter of
the
Cisco 10000 Series Router Quality of Service
Configuration Guide
.
Step 3
Router(config-pmap-c)#
priority level
level
(Optional) Defines multiple levels of a strict priority service
model. When you enable a traffic class with a specific level of
priority service, the implication is a single priority queue
associated with all traffic enabled with the specified level of
priority service.
level
is a number that indicates a specific priority level. Valid
values are from 1 (high priority) to 4 (low priority). Default: 1
Step 4
Router(config-pmap-c)#
police
bps
[
burst-normal
]
[
burst-max
] [
conform-action
action
]
[
exceed-action
action
]
[
violate-action
action
]
(Optional) Configures traffic policing.
bps
is the average rate in bits per second. Valid values are 8000 to
200000000.
(Optional)
burst-normal
is the normal burst size in bytes. Valid
values are 1000 to 51200000. The default normal burst size is
1500 bytes.
(Optional)
burst-max
is the excess burst size in bytes. Valid values
are 1000 to 51200000.
(Optional)
conform-action
action
indicates the action to take on
packets that conform to the rate limit.
(Optional)
exceed-action
action
indicates the action to take on
packets that exceed the rate limit.
(Optional)
violate-action
action
indicates the action to take on
packets that violate the normal and maximum burst sizes.
Step 5
Router(config-pmap-c)#
set cos
value
(Optional) Sets the Layer 2 class of service (CoS) value of an
outgoing packet.
value
is a specific IEEE 802.1Q CoS value from 0 to 7.
Step 6
Router(config-pmap-c)#
bandwidth
remaining
ratio
(Optional) Specifies a bandwidth-remaining ratio for class-level
or subinterface-level queues to be used during congestion to
determine the amount of excess bandwidth (unused by priority
traffic) to allocate to non-priority queues.
ratio
specifies the relative weight of this subinterface or queue
with respect to other subinterfaces or queues. Valid values are
from 1 to 1000.
Step 7
Router(config-pmap-c)#
exit
Exits policy-map class configuration mode.
