Configuring Uniform Mode
This section describes how to configure the following:
•
•
•
The steps that follow show one way, but not the only way, to configure the Uniform mode.
Note
Configuring the Ingress PE Router—Customer Facing Interface
For Uniform mode, setting the trust state to IP precedence or IP DSCP allows the PFC3BXL or PFC3B
to copy the IP PHB into the MPLS PHB.
This description applies to PFC3BXL or PFC3B QoS for LAN or OSM ports. For information about

To configure a policy map to set the MPLS EXP field in imposed label entries, perform this task:

Purpose
Enables QoS functionality.
Creates an IPv4 access list.
Creates a class map.
Configures the class map to filter with the ACL created in
Step 2.
Creates a named QoS policy.
Configures the policy to use the class map created in step 3.
Configures policing, including the following:
• Action to take on packets that conform to the rate limit
specified in the SLA.
Action to take on packets that exceed the rate limit
•
specified in the SLA.
Selects an interface to configure.
Configures received DSCP as the basis of the internal DSCP
for all the port's ingress traffic.
Attaches the policy map created in step
an input service policy.
