Quality of Service Commands
22
Command Usage
•
The set phb command is used to set an internal QoS value in hardware for matching packets
(see
Table 100, "Default Mapping of DSCP Values to Internal PHB/Drop Values"
). The QoS label
is composed of five bits, three bits for per-hop behavior, and two bits for the color scheme used
to control queue congestion by the
command and
command.
•
The
and set phb command function at the same level of priority. Therefore setting
either of these commands will overwrite any action already configured by the other command.
Example
This example creates a policy called “rd-policy,” uses the
command to specify the previously
defined “rd-class,” uses the set phb command to classify the service that incoming packets will
receive, and then uses the
command to limit the average bandwidth to 100,000 Kbps,
the burst rate to 4000 bytes, and configure the response to drop any violating packets.
Console(config)#policy-map rd-policy
Console(config-pmap)#class rd-class
Console(config-pmap-c)#set phb 3
Console(config-pmap-c)#police flow 10000 4000 conform-action transmit
violate-action drop
Console(config-pmap-c)#
service-policy
This command applies a policy map defined by the policy-map command to the ingress or egress
side of a particular interface. Use the no form to remove this mapping.
Syntax
[no] service-policy {input | output} policy-map-name
input - Apply to the input traffic.
output - Apply to the output traffic.
policy-map-name - Name of the policy map for this interface. (Range: 1-32 characters)
Default Setting
No policy map is attached to an interface.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
•
Only one policy map can be assigned to an interface.
•
First define a class map, then define a policy map, and finally use the service-policy command
to bind the policy map to the required interface.
Example
This example applies a service policy to an ingress interface.
Console(config)#interface ethernet 1/1
Console(config-if)#service-policy input rd-policy
Console(config-if)#
