Chapter 19
| Quality of Service Commands
– 455 –
Example
This example creates a policy called “rd-policy,” uses the class command to specify
the previously defined “rd-class,” uses the set ip dscp command to classify the
service that incoming packets will receive, and then uses the police flow 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 ip dscp 3
Console(config-pmap-c)#police flow 100000 4000 conform-action transmit
violate-action drop
Console(config-pmap-c)#
set phb
This command services IP traffic by setting a per-hop behavior value for a matching
packet (as specified by the
match command) for internal processing. Use the no
form to remove this setting.
Syntax
[ no ] set phb phb-value
phb-value - Per-hop behavior value. (Range: 0-7)
Default Setting
None

Command Usage
◆
The set phb command is used to set an internal QoS value in hardware for
matching packets (see Table 97, "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
police srtcm-color command and police trtcm-color
command.
◆
The set cos 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.
