Chapter 4 Attaching Service Policies
Verifying and Monitoring QoS Service Policies
Note
The
show pxf
commands are entered as
show hardware pxf
on the PRE1. For example, to
view a statistical summary of PXF column 0 for the specified interface, enter the
show hardware pxf interface
command.
Verification Example for QoS Service Policies
Example 4-20
shows the information displayed when you enter the
show policy-map interface
command. In the sample output, random early detection (RED) drop statistics display for each
IP precedence.
The sample output in
Example 4-20
is based on the following class map and policy map configurations:
class-map match-all prec_0_0
match access-group 100
class-map match-all prec_0_1
match access-group 101
class-map match-any class-default
policy-map wred_1
class prec_0_0
